What Is a Black Onyx Necklace?

A black onyx necklace is a fine jewelry piece featuring a pendant or stone made from natural black onyx — a variety of chalcedony quartz prized for its deep, uniform black color and smooth, glossy surface. Unlike black diamonds or black moissanite, black onyx offers a distinctly refined aesthetic that creates bold contrast against gold and silver settings.

At Esdomera, every black onyx necklace features genuine, ethically sourced natural black onyx set in 925 sterling silver or solid gold (10K, 14K, and 18K). Each pendant arrives on a fine chain, ready to wear or gift.

Color: Deep, uniform black with a smooth, polished surface
Hardness: 5–7 on the Mohs scale — durable for daily wear
Settings available: 925 Sterling Silver, 10K / 14K / 18K Solid Gold (yellow, white & rose)

Why Choose a Black Onyx Necklace?

Black onyx occupies a rare space in jewelry: simultaneously bold and versatile, dramatic and timeless. Its neutral black works with every skin tone and metal, making it exceptionally wearable.

Timeless aesthetic: Deep black never goes out of style.
Versatile: Pairs equally well with casual and formal wear.
Accessible luxury: The visual impact of black diamonds at a fraction of the cost.
Meaningful symbolism: Associated with strength, protection, and confidence.

Black Onyx vs. Other Black Gemstones:

Black Diamond: Onyx provides a smooth finish vs. diamond's metallic sparkle — more affordable for larger pendants.
Black Moissanite: Onyx offers understated elegance vs. moissanite's intense brilliance.
Black Tourmaline: Onyx has a more uniform, polished surface compared to the natural inclusions of tourmaline.

Black Onyx Symbolism & Meaning

Black onyx has been treasured for over 4,000 years. From Roman soldiers to Victorian mourning jewelry, it remains a stone of focus and unwavering confidence.

Strength & Protection: Believed to form a shield against negative energy.
Confidence & Power: Said to enhance self-discipline and personal authority.
Grounding: Associated with calm focus and emotional balance.

Black onyx is the traditional birthstone for Leo (July 23 – August 22) and the recognized gift for 7th wedding anniversaries.

These rings were wonderful.

Trotz Umbestellung immer noch falsche Größe

Trotz ausmessen mit Ringmaßband falsche Größe. Andere Ringe von anderen Anbietern in dieser Größe passen perfekt. Haben den Ring dann noch einmal kleiner bestellt in der Hoffnung das dieser dann passt, trotzdem weiterhin viel zu groß. Leider würde bei einer erneuten Bestellung der Ring nicht mehr rechtzeitig zu unserer Hochzeit ankommen wofür er gedacht ist.
Sonst ist der Ring wunderschön, weshalb wir ihn trotzdem behalten und anderweitig versuchen werden ihn anpassen zu lassen. würde fast schon sagen schöner als auf den Bildern. Nur würde sich für mich persönlich bei solch einem schmalen Ring in Zukunft keine Gravur mehr lohnen da diese mit dem bloßen Auge kaum zu erkennen ist, zu lesen gar nicht.

Our rings are made according to standard US sizes. We are sorry that the size did not fit, and we hope that the adjustment goes well and that you are still satisfied.
For the engraving, the space on such a narrow ring is unfortunately limited, so it can only be small. Thank you for your feedback – we will take it seriously and continue to improve.

Lovely!!

So so happy with our wedding rings!! Im completly in love!! 🥰 Esdomera is the perfect jewlery, they're so kind, and fast, and they have the most beautiful designs I've ever see.

Stunning!

Truly an amazing experience! I completed a custom order with Esdomera. They were super patient and responsive, especially with how specific and picky I was. They made changes when I overlooked things and also helped me pick design options that made the most sense. The ring arrived 3 weeks after we finalized the design, and it is everything I wanted! I was nervous about ordering from an online shop outside the US but they really put me at ease and they stand behind their work. I also received the verification report for my stone. 10/10!!

0/0 Would not buy!

I ordered this ring and from the pictures on the website it looked like a beautiful ring. After waiting a month for it to get to me, I was SO disappointed when I opened it. It looks nothing like the picture! I knew it was gold plated, but I figured a 140 dollar ring would look like real gold. Nope! The “yellow gold” plating looks orange! So orange I just knew it was going to turn my finger green. The stones were okay but the whole thing overall is awful. I messaged the company asking for a refund but they said it was “personal preference” (more like false advertising!) and were going to take ten percent of my refund and then twenty percent for shipping charges. 0/0 would not recommend!!
