5.1 x 3.3 x 1.8 cm. I collected calcites for 20 years, since I was a kid, and in all that time I had never seen or been offered such a nice calcite from these classic mines. I obtained it from Herb Obodda in the early 1990s and have had it ever since. It came to him from the Schwethelm collection, in Germany, and probably left the US soon after being mined in the late 1800s. Complete all around, a fine piece I was happy to own for about 15 years in my own collection. Ex. Robert Lavinsky Collection.
