4.15 ct Blue Aquamarine - Cushion

This 4.15-carat aquamarine is cut as a cushion measuring 14.2 x 8.6 x 5.7 mm, with a blue body color, sourced from Nigeria.

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 is wholly untreated, its color finished by geology rather than by any furnace or enhancement.

Its exact combination of color, cut, and origin is its own, the kind of center stone you choose on purpose and build a piece around. Caveman Gems hand-selects every gemstone and photographs it in good light, to give you the truest look a screen can.
