Substantial 18.12ct Brazilian Aquamarine with rainbow flashing

This very large aquamarine measures a whopping 23.4mm x 15.6mm x 9mm, and exhibits a stunning sky blue hue with light saturation. A mix of glittering and liquid flashing frames its table, but the real star of the show is whats on the inside. This aquamarine has a large feather in it that refracts the light, giving it a large swath of rainbow colors suspended under its surface. The prismatic effect is strong, and is easily observed through movement. Sourced from Brazil. Untreated!!!
