Calcite. A Calcite Scepter from Russia and a Calcite included with Boulangerite from Romania
So how do you decide what to include in your collection. I am a collector who enjoys the pursuit, the treasure hunt. I attend so many shows as a dealer and as a wholesale buyer I needed to develop a strategy to develop my own collection. I decided on thumbnails and even though there are fewer and fewer good thumbnail dealers out there my collection still was overflowing with minerals I had only purchased because they were available. Now I focus. I will consider all thumbnail minerals but I pursue an agenda until I have filled that space. Currently I am collecting quartz from US locations. I have been pursuing that goal for about 2 years. Another strategy is to only purchase interesting examples of common minerals. So here we have two calcites - my scepter and my space ship.
