This is a gorgeous all natural aquamarine from Okene, Kogi State, Nigeria. Nigeria has been the source of many gems in recent years, including some very fine aquamarine such as this.  The color is a rich bright medium blue with just a hint of green and no gray tones.  This gem is extremely clean, with just one tiny feather in a corner, where it could be hidden under a prong when set.  The inclusion is so small it can’t be seen without a 10x loupe–its an eye clean gemstone.  Very fine aquamarine such as this is a rarity–most aqua on the market is much more pale or has a gray overtone. 

I faceted this gem in my custom “Hyperbola” brilliant oval design.  The resulting gem is bright and scintillating in the hand–very striking.  The gem weighs 2.28 carats and measures 8.9 x 7.5 x 6.0 mm.  It would make a superb center stone for a ring or pendant.
