Black Onyx Pendant Necklace

Black Onyx Pendant Necklace

Monica Vinader Black Onyx Pendant Necklace is a limited-edition gemstone pendant necklace built around a deep black onyx ID-style charm and recycled sterling silver. The original Nordstrom listing specifies an 18-inch necklace, an engravable reverse side and a choice of recycled sterling silver or recycled sterling silver with an 18k-gold finish. Monica Vinader’s current Havana version of the design pairs the same black onyx ID pendant concept with an adjustable curb chain.

The pendant itself measures approximately 20 mm high, 14 mm wide and 2 mm thick on Monica Vinader’s current Havana Black Onyx specifications. The manufacturer currently offers the related necklace set in sterling silver and in an 18k Gold Vermeil version, while its current curb chain adjusts from approximately 18 to 20 inches.

Rather than treating the black stone as decoration alone, the necklace gives it a strong graphic role. The dark polished surface contrasts sharply with silver or gold metal and leaves the reverse of the pendant available for personal engraving. For shoppers comparing necklace silhouettes on Erothots, it belongs naturally within the Jewellery collection alongside more layered designs such as the Pearl Multi Row Chain Necklace.

About Black Onyx Pendant Necklace

The Black Onyx Pendant Necklace is best understood as a gemstone ID pendant rather than a small solitaire necklace.

Its central element is a rectangular black onyx charm with softened edges and a relatively broad face. The front uses the black stone as the visual focal point, while the reverse can be engraved, turning the pendant from a purely decorative piece into something more personal. Nordstrom specifically described the necklace as engravable, and Monica Vinader continues to offer complimentary engraving on the corresponding Havana Gemstone ID Pendant Charm.

The design is also deliberately substantial enough to be noticed without becoming an oversized statement necklace. At about 2 cm high, the pendant sits in a useful middle ground between tiny charm necklaces and large medallions.

That scale makes it particularly easy to wear on its own or incorporate into a layered necklace arrangement.

Black Onyx Pendant Necklace Design And Silhouette

The pendant uses a clean rectangular format instead of a traditional round gemstone bezel.

That decision gives the black stone a more contemporary appearance.

The relatively flat 2 mm thickness also keeps the design from behaving like a bulky cabochon or heavy gemstone medallion. Its 20 x 14 mm face provides enough black surface area to stand out clearly against clothing while remaining compact around the neckline.

Because onyx is visually opaque and dark, the shape matters more than faceting. This necklace does not depend on the sparkle associated with diamonds, crystals or highly faceted transparent stones.

Instead, the effect comes from the contrast between smooth black gemstone and reflective precious metal.

That makes the design particularly useful when an outfit already contains pattern, texture or other jewelry and another sparkling element would feel excessive.

Black Onyx Gives The Pendant Its Graphic Look

Onyx belongs to the chalcedony family of quartz materials.

Black onyx jewelry is valued largely for its dense-looking dark color and ability to take a polished surface. Gemological information from the Gemological Institute of America also shows that black chalcedony and onyx materials have historically been treated to achieve consistent dark coloration, so a black-on-color appearance by itself should not be taken as proof that a stone is completely untreated.

Monica Vinader describes the pendant specifically as black onyx but does not publish a treatment report for the individual stone on the current product page.

For ecommerce copy, that means it is appropriate to call it black onyx but not to add unsupported phrases such as untreated, completely natural black, or rare untreated onyx.

The gemstone’s practical design value is much easier to verify: it creates an intense dark center that works very differently from clear crystals or pale stones.

The Necklace Should Not Be Sold On Crystal-Healing Claims

Black onyx has accumulated a long history of symbolic meanings, and jewelry sellers sometimes associate it with protection, willpower, grounding or emotional benefits.

Monica Vinader itself sometimes mentions traditional symbolic associations when discussing its gemstones.

Those associations are better treated as jewelry tradition and symbolism, not medical or psychological effects.

There is no good basis for claiming that wearing the Black Onyx Pendant Necklace can clinically reduce anxiety, improve concentration or alter physical health.

The more useful product description focuses on the gemstone’s appearance, construction and styling potential.

Recycled Sterling Silver Is A Real Precious-Metal Base

The silver version is not silver-tone base metal.

Nordstrom lists the necklace as recycled sterling silver, and Monica Vinader states that its sterling-silver jewelry is made from 100% recycled silver.

Sterling silver is an alloy containing 92.5% silver, which is why it is commonly referred to as 925 silver. Monica Vinader gives the same 92.5% description in its current material information.

The FTC’s jewelry guidance is useful here because it distinguishes sterling silver from silver-plated base metal.

This means the silver option has sterling silver through its metal structure rather than merely a thin silver-colored coating over an unidentified base.

The Gold Version Uses Sterling Silver Underneath

The gold-finish version should not be described as solid 18k gold.

Nordstrom lists it as recycled sterling silver with 18k-gold plate, while Monica Vinader currently identifies the corresponding Havana version as 18k Gold Vermeil & Black Onyx.

Monica Vinader’s current Gold Vermeil construction uses at least 2.5 microns of 18k gold layered over 925 sterling silver.

That is a more substantial specification than simply writing “gold tone.”

The FTC similarly describes vermeil as a gold surface application over sterling silver and historically uses a minimum 2.5-micron thickness in its guidance.

So the correct material description for the manufacturer’s current gold Havana version is:

18k Gold Vermeil over 925 sterling silver with black onyx.

It should not be shortened to “18k gold necklace,” which could imply solid gold throughout.

Why The 2.5-Micron Vermeil Detail Matters

A gold layer is extremely thin when measured compared with the full thickness of the jewelry, so plating specifications are normally expressed in microns.

Monica Vinader states that its Gold Vermeil pieces receive at least 2.5 microns of 18k gold over sterling silver.

That helps distinguish its current vermeil construction from very lightly plated fashion jewelry.

It does not make the surface permanent.

Even comparatively substantial gold plating can gradually change through abrasion, repeated moisture exposure, cosmetics, sweat and everyday wear.

One useful advantage of buying within Monica Vinader’s own system is that the company currently offers replating services when vermeil loses color over time.

The Pendant Is Engravable On The Reverse

Personalisation is one of the necklace’s strongest functional design details.

Nordstrom describes the back of the black onyx charm as ready for engraving, and Monica Vinader’s current Havana pendant page continues to offer complimentary engraving.

Because the gemstone occupies the front, engraving is placed on the metal reverse rather than cutting into the onyx itself.

That keeps the visible stone clean while allowing the other side to hold initials, a short date, symbols or another small personal detail according to the engraving options available from the retailer or manufacturer.

A personalized reverse also means the necklace does not have to look like a customized item from the front.

It remains a simple black onyx pendant until it is turned over.

Chain Length Needs A Small Specification Note

There are two current length references attached to this design.

The Nordstrom Black Onyx Pendant Necklace listing specifies 18 inches.

Monica Vinader’s current Havana ID Black Onyx Gemstone Curb Chain Necklace uses a 46–50 cm / approximately 18–20 inch adjustable curb chain.

This likely reflects different retailer configurations or product generations rather than a reason to average the two numbers.

If Erothots inventory corresponds to the original Nordstrom necklace, 18 inches is the appropriate listing specification.

If it corresponds to Monica Vinader’s current two-piece Havana set, the adjustable 18–20 inch measurement should be used instead.

Checking the physical tag or included chain before publishing the final variation is more accurate than silently combining those versions.

How The Length Changes The Fit

An 18-inch necklace typically places the pendant around the upper chest on many wearers, but exact placement varies with neck circumference and body proportions.

The current 18–20 inch adjustable manufacturer chain gives slightly more flexibility.

At its shorter position, the pendant can sit closer to the neckline.

At its longer position, it has more separation from shorter chains when layered.

The 20 mm pendant size is also important here. It is large enough to remain visible at either length without becoming a long medallion.

For someone who prefers a necklace that already creates multiple levels without needing separate chains, Erothots’ Pearl Multi Row Chain Necklace takes a very different approach with three built-in strands and an adjustable extender.

Curb Chain Adds More Presence Than A Very Fine Chain

Monica Vinader’s current Havana set pairs the pendant with a curb chain.

Curb links lie relatively flat and create a more visible metal line than an ultra-fine chain.

That works well with the ID pendant because the charm itself is not tiny.

A very delicate chain could make the pendant feel disproportionately heavy visually, while a curb chain gives the necklace more balance from clasp to centerpiece.

The design is still simpler than Erothots’ layered Pearl Multi Row Chain Necklace, so the Black Onyx Pendant Necklace can be the only necklace worn without looking unfinished.

Personalisation Makes The Necklace Work Well As A Gift

The engravable back adds a function that many gemstone necklaces do not have.

A black onyx front keeps the piece visually neutral and wearable, while the reverse can hold a detail that has meaning to the recipient.

That gives it a different character from a decorative necklace chosen entirely for color or sparkle.

Monica Vinader currently positions engraving as a major part of its personalized-jewelry service and offers engraving across compatible pendants and other pieces.

The engraving option should still be treated separately from the gemstone.

The onyx does not become more valuable or technically different because the reverse metal has been customized.

Black Onyx Works With Both Silver And Gold

The same black stone behaves quite differently depending on the surrounding metal.

With sterling silver, the contrast is cool and graphic. The black-and-silver combination can work particularly well with grey, navy, white, black and cooler metallic accessories.

With 18k Gold Vermeil, the contrast becomes warmer. Yellow gold around the black stone produces a stronger light-versus-dark effect and coordinates naturally with other warm-metal jewelry.

Black is also useful in mixed-metal styling because it does not visually belong exclusively to either metal family.

A person wearing the silver version could pair it with gold earrings, while the gold-vermeil version can still work beside sterling-silver rings or bracelets.

The Erothots Jewellery collection includes both silver- and gold-tone pieces, making mixed-metal styling easier than trying to make every accessory identical.

Ways To Style Black Onyx Pendant Necklace

On its own, the pendant works well with a crew neck, open shirt, fine knit or simple dress because the dark center creates enough contrast to remain visible without additional stones.

Layering changes the effect.

A shorter fine chain can sit above the 18-inch necklace while the onyx becomes the lower focal point. If using Monica Vinader’s adjustable 18–20 inch chain, the extra length can help separate it from another necklace.

The pendant can also be paired with earrings that provide more movement. Erothots’ Cherryparty Chandelier Earring represents a substantially more decorative earring silhouette, so keeping the necklace relatively clean can stop the jewelry combination from becoming too visually crowded.

For a softer, more layered neckline, the Pearl Multi Row Chain Necklace takes the opposite route by combining several chain textures with faux pearls.

Best Occasions For This Style

The black onyx and simple rectangular shape do not tie the necklace to one type of event.

With a shirt, blazer or plain knit, it works as a compact everyday pendant.

With a simple evening neckline, the polished black stone gives a stronger jewelry focus without relying on crystals.

The engraving option can also make it appropriate as a birthday, graduation or milestone gift, while the plain front keeps the personal message private.

For occasions where a much larger visual statement is wanted, a multi-row necklace or chandelier earring will naturally create more impact.

The Black Onyx Pendant Necklace is more about a single strong focal point.

Caring For The Black Onyx

Monica Vinader recommends wiping gemstone jewelry with a soft cloth after wear to remove surface oils and perfume residue. The company also advises against swimming in jewelry because chlorine and salt water can damage or dull pieces.

That is particularly sensible for this necklace because both the gemstone and metal finish need consideration.

Harsh abrasive cleaners are unnecessary for the polished onyx.

Perfume, body lotion and other cosmetic products are better allowed to dry before the necklace is put on, reducing direct residue on both the stone and metal.

GIA notes that chalcedony materials are around 6.5 to 7 on the Mohs hardness scale and that dyed chalcedony can be affected by high heat.

That means onyx is suitable for normal jewelry wear, but it is not scratch-proof or heat-proof.

Sterling Silver And Vermeil Need Slightly Different Care

The silver and gold versions share the same stone but do not have identical metal surfaces.

Bare sterling silver can gradually tarnish as it reacts with its environment. Monica Vinader says appropriate silver polish can be used on its silver jewelry.

Gold vermeil requires a gentler approach because the visible gold is a surface layer.

Monica Vinader recommends its polishing cloth rather than artificial cleaning solutions for gold jewelry.

With either version, cleaning the necklace as one complete gemstone piece should be conservative. Aggressive polishing around the stone setting or repeated exposure to strong cleaners is unnecessary.

The Five-Year Warranty Adds Useful Aftercare

Monica Vinader currently provides a five-year warranty across its jewelry and offers lifetime repair services afterward for a fee.

The manufacturer also states that replating is available for vermeil jewelry that loses color over time.

That is particularly relevant to a necklace intended for frequent wear.

Gold-plated surfaces naturally experience wear, so access to manufacturer replating is more meaningful than pretending the finish will remain unchanged forever.

The warranty does not remove the need for normal jewelry care, but it gives the material construction a more complete ownership story than a plated piece with no documented aftercare program.

Recycled Metal Is Part Of Monica Vinader’s Material Approach

Monica Vinader states that it uses 100% recycled sterling silver and currently describes its gold and silver sourcing around recycled precious metals.

Nordstrom’s original product listing also specifically calls the metal recycled sterling silver, rather than leaving the sustainability claim only on the manufacturer’s general pages.

Nordstrom additionally identified Monica Vinader as meeting its Responsible Brands criteria and referenced the brand’s Butterfly Mark certification on the original necklace listing.

Those claims should remain attributed to the companies and certifications that make them.

They describe sourcing and business practices, not a technical indication that recycled silver is somehow a different grade of sterling silver when worn.

What Makes Black Onyx Pendant Necklace Different

The strongest part of the design is the combination of dark gemstone, substantial precious-metal construction and a hidden personalisation surface.

The black onyx face creates the visible focal point.

The recycled sterling-silver structure gives the necklace a defined precious-metal base.

The gold version uses Monica Vinader’s current 18k Gold Vermeil construction rather than unidentified gold-tone metal.

The reverse can be engraved without changing the clean appearance of the front.

The dimensions are also useful and specific: approximately 20 mm high, 14 mm wide and 2 mm thick.

The only specification that needs careful attention is chain length. Nordstrom’s original listing specifies 18 inches, while Monica Vinader’s current Havana set uses an adjustable 18–20 inch curb chain. The exact Erothots inventory should determine which version is published.

Final Note

Monica Vinader Black Onyx Pendant Necklace is a recycled sterling-silver gemstone necklace centered on a 20 x 14 mm black onyx ID-style pendant with an engravable reverse. The original Nordstrom version lists an 18-inch length, while Monica Vinader’s corresponding current Havana set combines the pendant with an adjustable 18–20 inch curb chain.

Material wording is important. The silver option is recycled sterling silver, while the manufacturer’s current gold version is 18k Gold Vermeil over 925 sterling silver, with Monica Vinader specifying at least 2.5 microns of 18k gold. It should therefore not be described as a solid 18k gold necklace.

The black onyx provides a polished, graphic centerpiece rather than gemstone sparkle, and the engravable back adds personalisation without changing the clean front of the design. Symbolic meanings sometimes attached to onyx can be mentioned as tradition, but the necklace should not be marketed with unsupported healing or health claims.

For care, Monica Vinader recommends gently wiping gemstone jewelry after wear and keeping pieces away from swimming water and unnecessary chemical exposure. The company also currently backs its jewelry with a five-year warranty and lifetime repair service, with replating available for vermeil pieces when required.

For related pieces on Erothots, shoppers can browse the Jewellery collection, compare a built-in layered neckline with the Pearl Multi Row Chain Necklace, or balance the simple pendant with the more decorative Cherryparty Chandelier Earring.
