For sale is a beautiful calcite crystal with green quartz crystals on magnesite from Biggenden, Qld. This is an outstanding specimen from a very prolific mine, now long closed. The last pic show a rear view of the specimen with and unidentified tan colored mineral, possibly siderite. Calcite crystal is over 50mm long!! Having a full run of the saturated green quartz , next to the outstanding calcite crystal is quite a bonus, green quartz like this is not common from the locality. The main calcite, pristine, and classic Biggenden, is approx, 50mm long! This specimen is way way better in person!
