Intricate 49.84ct Fossil Agate

This is such a great piece. The well defined shell fossils stand out against the rich black agate making this piece a stunning window into the past. And with slight magnification, you can observe tiny crystal formations in the shells. It measures 35mm x 25.2mm x 7.4mm, and has a smooth polished cut with a glistening luster. Sourced form Costa Rica. Untreated.
