Colourless Mogok Spinel 0.62ct | Untreated | Rare | UK

A rare, eye-clean colourless spinel from Mogok at 0.62ct. The elongated 5.7 × 4.3mm outline gives this stone a distinctive shape — wider than it is tall, clean, and entirely without colour. Colourless spinel in eye-clean quality is one of the scarcest finds in the natural gemstone world, and this example represents excellent value for a collector or designer who understands the rarity involved.

Why Colourless Spinel?

Colourless spinel is pure natural spinel with no trace elements — as close to the mineral's unaltered state as exists. Unlike the commercial markets for colourless diamonds or sapphires, colourless spinel is produced in tiny quantities and receives no marketing support. For a knowledgeable buyer, that is exactly the point. Clean, bright, and entirely natural — suitable for a minimalist bespoke ring, an accent in a mixed-stone design, or a serious mineral collector's portfolio. No treatments. No enhancements of any kind.
