Spinel has long been under-appreciated as a fine gemstone, after spending centuries being confused with sapphire and ruby–and for good reason, as they are nearly identical in brilliance and dispersion.  Spinel is slightly less hard than sapphire, but still hard enough to be a durable gem, as its also quite tough; its suitable to be used in everyday jewelry.  This particular spinel is a rich blue color, similar to a peacock or royal blue.  The gem is very clean and scintillating in the hand.

I faceted this spinel in my modified and optimized version of the classic diamond round brilliant cut.  The resulting gemstone is gorgeous–extremely bright and lively in the hand.  It weighs 0.89 carats and measures 5.7 x 3.9 mm.  It would make a perfect center stone for an engagement ring!
