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. The gem is all but internally flawless, and while the macro image shows some growth/strain lines, they aren’t visible without a loupe. Extremely 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 “Helena” brilliant oval design. The resulting gem is bright and scintillating in the hand and very striking. The gem weighs 4.03 carats and measures 11.0 x 9.3 x 7.3 mm. It would make a superb center stone for a ring or pendant.
