0.77 ct White Opal - Oval

At 0.77 carats, this opal from Australia carries its white color through an oval cut, measuring 8 x 6.1 x 2.5 mm.

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. Australia is a major commercial gem source, best known for its opal and sapphire. It is entirely untreated; no heat, no enhancement, the color exactly as the earth made it.

A genuine opal at a size and price you can actually wear, the real thing rather than a machine-grown copy. Hand-selected and filmed by Caveman Gems in good light, shown as honestly as a screen allows.
