- Polished into the shape of a lemon wedge (and with pretty lemony color, too), this is a specimen of smithsonite that almost certainly dates back to the 1800s. It is from the island of Sardinia off the coast of Italy. The backside and bottom are a creamy white color - the side facing you is a band of the translucent yellow smithsonite.
