I like how this bubble moves from one side of the cavity to the other. It’s an elongated cavity which matches the style of the Cabochon! $60! Could almost use this piece as a level!

A monstrous Citrine from Brazil with great color, clarity, and well cut! A nice piece for a collection, set it side by side with a monstrous citrine! $150! Usually $400. Available on @over_100_dollar_gems
