    This nicely sized Drotops Trilobite displays excellent detail. With its distinct spines and undulated position, the specimen has a surreal feel to it, almost life-like. Most importantly, the eyes of the Trilobite also are well preserved in that the lenses also display excellent detail. A very nice piece for anyones collection.

    We were able to obtain a handful of BB grade, loose Herkimer diamonds which we're happy to offer for a more reasonable price than some of the lessor quality material we've seen on the market.
