Glendonite (Red Calcite) with Sandstone #12 measures approximately 1 1/8" x 15/16" x 5/8" (30mm x 25mm x 16mm) and weighs .4 ounces (10.3 grams). Glendonite is a Calcite pseudomorph after Ikaite. That means the Glendonite (Red Calcite) took the crystal form of the Ikaite, instead of its own form, when it replaced the Ikaite, taking its shape. You may never actually see another one of these--they are truly that rare! Each of these have Sandstone sprinkled on them, but they are not the "Shmoos". They carry the energy of both crystals, though. Judy Hall has written this up under "Glendonite" in Crystal Bible 3.
