4.18 ct White Opal - Freeform

This 4.18-carat opal is shaped as a freeform measuring 16.2 x 11.2 x 5.8 mm, with a white body color, sourced from Ethiopia.

Opal is hydrated silica that can break white light into a play of living color, a fire no two stones repeat; it holds up to a fifth of its weight in water, which is why it glows in a way nothing crystalline does. 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. Caveman Gems hand-selects every gemstone and films it in good light, to give you the truest look a screen can.
