2.53 ct Blue Aquamarine - Trillion

At 2.53 carats, this aquamarine from Nigeria carries its blue color through a trillion cut, measuring 11 x 7.6 x 9 mm.

Aquamarine is the blue beryl, colored by iron, and grows in larger clean crystals than its cousin emerald, which is why it cuts so bright. Nigeria's gem fields rose to prominence in the 1990s and remain a significant modern source. It carries no treatment of any kind, so the color you see is the color that came out of the ground.

No two of these line up the same way on color, cut, and origin at once, which is what makes choosing this one feel deliberate. Hand-selected and photographed by Caveman Gems in good light, shown as honestly as a screen allows.
