Dark Blue Grey Spinel – 2.3 Carats (7 x 7.5 mm)

Grey spinel is one of the rarest stones that most people have never heard of. Unlike sapphires or diamonds, spinel has no major marketing category to itself — which means the people who know it, choose it specifically. This one is a dark, smoky blue-grey: a color that reads like deep water at dusk, the kind of light that holds rather than throws.

The Stone
Spinel was mistaken for ruby and sapphire for most of recorded history — the Black Prince's Ruby in the British Imperial Crown is a spinel. It wasn't until the nineteenth century that gemologists distinguished the species. Since then, fine spinel has been prized by collectors precisely because the market hasn't caught up to it yet: you can still acquire a genuinely exceptional stone at a fraction of what its optical equivalent in sapphire would cost. This 2.3-carat dark blue-grey stone is optically bright with clean faceting — 7 x 7.5mm, a size that works well in a solitaire or as a center stone in a custom design. Natural, untreated.
