The Revival of Vintage Gemstones: Black Onyx
 In the swift swooping world of jewellery, some gemstones stand the test of time for their silent power and grace. Black Onyx is one such gem — a stone rich with history, symbolism and timeless elegance. Historically symbolic of strength, stability, protection and healing, the Black Onyx stone is back in the world of modernity as an alternative for everyday luxury and the perfect dose of vintage allure.
But how is it that this stone is having such a resurgent moment? And how are designers and collectors reinventing it for the 21st century?
Join us on our expedition into the history of Black Onyx and how it was rediscovered in the realm of vintage gemstones.
What Is Black Onyx?
 Black Onyx is a chalcedony quartz mineral with a smooth, lustrous surface and deep, uniform black colour. Its striking contrast against metals like silver, gold, or platinum makes it a favourite in jewellery design.
Appearance: Jet black in its purest form, though often enhanced through heat treatment or dyeing to achieve an even colour.
Composition: A variety of chalcedony, formed by silica deposits in lava cavities over millions of years.
Hardness: 6.5–7 on the Mohs scale, making it durable for everyday wear (Source: GIA – Gemological Institute of America).
Historical Legacy of Black Onyx
 Black Onyx is one of the oldest gemstones used in adornment:
- Ancient Egypt: Used in jewellery and amulets as far back as 3100 BCE (Source: Metropolitan Museum of Art, New York).
- Roman Empire: Crafted into cameos and intaglios for seals and signet rings, as wax did not stick to onyx.
- Victorian Era: Gained immense popularity in mourning jewellery, as its deep black aligned with the sombre elegance of Queen Victoria’s fashion (1837–1901).
This historic association with elegance, strength, and symbolism is central to why it resonates again in today’s jewellery revival.
Why Black Onyx Is Making a Comeback
The revival of vintage gemstones aligns with modern consumer desires for meaningful, ethical, and timeless jewellery. Black Onyx is returning for several reasons:
Gender-Neutral Appeal – Its bold yet understated style makes it popular in both men’s and women’s jewellery.
Minimalist Luxury – Its sleek monochrome look complements both contemporary and vintage aesthetics.
Symbolic Strength – Associated with grounding energy, emotional balance, and resilience, aligning with the wellness-driven choices of today’s buyers.
Sustainable Heritage – Vintage Black Onyx pieces, especially Victorian cameos or Art Deco jewels, are eco-conscious alternatives to newly mined stones.
Modern Jewellery Trends with Black Onyx
 Designers are reimagining Black Onyx with fresh, versatile expressions:
Minimalist Pendants – Smooth onyx discs or geometric cuts in sleek silver or platinum chains.
Statement Rings – Large cabochons set in yellow or rose gold, often accented with diamonds.
Men’s Jewellery – Signet rings, cufflinks, and pendants crafted with Onyx are resurging in popularity.
Art Deco Inspirations – Black Onyx is frequently paired with emeralds, sapphires, and diamonds to recreate the bold contrast of 1920s design.

Black Onyx as an Investment
Black Onyx is not as rare as gemstones like Black Opal or Trapiche Emerald; however, it´s become widely popular in antique and vintage Onyx jewellery at auction houses worldwide. Both Sotheby’s and Christie’s regularly carry Art Deco Onyx & Diamond Cartier pieces at auction, and have been known to fetch 5–6 figure sales (provenance dependent) (backup file from Sotheby’s Auction Records, 2021–2023).
Victorian Mourning brooches and Edwardian Cameo lockets are still immensely popular because not only are they well-made, but they are history in the making! So, it’s not rare and therefore doesn’t have value, no, but its historical importance and design desirability is appealing to a smart collector.
Sustainability & Ethical Value
 Black Onyx aligns with the slow luxury movement, especially when buyers choose antique or repurposed pieces. By investing in vintage jewellery, consumers reduce environmental impact while preserving cultural craftsmanship. Modern jewellers are also adopting responsibly sourced onyx, further boosting its ethical appeal.
Styling with Black Onyx
- Evening Elegance: Pair a vintage Onyx cocktail ring with a velvet dress or tuxedo for instant sophistication.
- Minimalist Daywear: A simple Onyx pendant or studs elevate casual outfits.
- Layered Luxe: Combine Onyx with metals like gold or platinum for high-contrast chic.
Its versatility makes it a timeless wardrobe gemstone.
Final Thoughts
More than a trend, the reprise of black onyx is a comeback for jewellery with depth, meaning and timeless beauty. From Egyptian amulets to Victorian cameos and Art Deco treasures, the gemstone has never lost its allure. Now, in an age and society wary of its impact on the earth, souls and society of the past, people want to buy jewellery with soul, symbolism and sustainability- Black Onyx takes centre stage- as it is again the Zeitgeist stone. It is a reminder that sometimes the most powerful statements are best made in black and white.
