Blue Grey Spinel – 2.21 Carats (7 x 8 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 blue-grey that reads like a clear sky before a storm: a color that shifts between steel and slate depending on the light.

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 2.21-carat blue-grey stone is expertly faceted for maximum brilliance — 7 x 8mm, an elongated shape that works particularly well in signet rings, engagement rings, or pendants. Natural, untreated. What you see is what the earth made.
