_small.jpg) | Tridymite is a high temperature, low pressure polymorph of Quartz. It is hard to see the fine twinned bladed cyclic twinned crystals but they are found with a loop. They are a bit small but hard to see without a loop since the white on White is hard to contrast. ex John Holfert specimen |
