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 extremely fine aquamarine such as this one.  The color is a rich medium blue with just a hint of green and no gray tones.  The gem has outstanding clarity.  Fine gem aquamarine with this level of saturation and clarity are quite uncommon.

I faceted this gem in my custom “Testudo” brilliant oval design, specially optimized for beryl.  The resulting gem is bright and scintillating in the hand and very striking.  The gem weighs 5.41 carats and measures 12.9 x 9.8 x 7.8 mm.  It would make a superb center stone for a ring or pendant.
