The Spinel: The Understudy Gem Finally Takes Centre Stage

For over five centuries, the 170-carat 'Black Prince's Ruby' has sat proudly in the British Imperial State Crown – yet it is not a ruby at all, but a spinel. This case of mistaken identity is far from unique; spinel has been the perennial understudy of the gem world, overshadowed by its more famous cousins. Its beauty, however, is now being recognised as exceptional in its own right. Spinel offers a veritable rainbow of colours, from fiery crimson to electric cobalt, often with a clarity that rivals diamond. Modern connoisseurs are actively seeking it for its rarity, brilliance, and compelling backstory.

Spinel occurs in a richer spectrum than almost any other gem: vivid reds, hot pinks, cool blues, violet, orange, and even rare grey and black. The most coveted are the intense crimson that mimics the finest Burmese ruby and the piercing cobalt blue from Vietnam or Sri Lanka. Unlike many coloured gems, spinel is singly refractive, which endows it with a sharp, glassy brilliance that seems to glow from within. Its hardness of 8 on the Mohs scale makes it durable enough for daily wear, yet it remains significantly more affordable than ruby or sapphire of comparable quality. This combination of beauty, durability, and value makes it a wise choice for both collectors and those seeking a distinctive piece of fine jewellery.

Why Now?

The rise of the informed collector has driven a new respect for spinel. Ethical mining from deposits in Tanzania, Myanmar, and Tajikistan appeals to the conscience-driven buyer, particularly because spinel is almost never heat-treated or enhanced. Major jewellery houses have championed it: designers like JAR and Vhernier have created iconic pieces featuring the gem, and auction results have steadily climbed. A well-cut spinel can actually outperform a diamond in fire, displaying a dispersion that catches the eye from across a room. For the buyer who wants a gemstone with a story – one that has duped royalty and now stands on its own merits – spinel is the perfect choice.

When shopping for a spinel, look for rich, saturated colour and minimal visible inclusions. The cut should prioritise the gem's colour over carat weight; a beautifully proportioned cushion or oval cut will maximise its brilliance. Set in 18-carat gold or platinum, a spinel makes a statement piece that is both contemporary and steeped in history. Whether as a cocktail ring, a pair of earrings, or a pendant, it offers a unique narrative. This is a gem that has waited centuries for its moment in the spotlight – now is the time to let it shine.
