11.00 ct Colorless Opal - Trillion

This 11-carat opal is cut as a trillion measuring 20.2 x 18 x 6.1 mm, showing a colorless face, 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 is entirely untreated; no heat, no enhancement, the color exactly as the earth made it.

One of a kind, it exists exactly once; there is no second example to size up or down. It is the rarer object, and the kind of gemstone that becomes an heirloom. Caveman Gems hand-selects every gemstone and films it in good light, to give you the truest look a screen can.
