If you read the list of banned gems, those that end in Quartz are not accepted. This is because my Co-GM is not comfortable with it and he has stuck with me since beyond the beginning so unfortunately I cannot accept Angel Aura Quartz. Here are some clear or clearish gems below, since I feel bad about all the no's :( Clear Gems - Danburite - Rutile Topaz -Spodumene <--- some other colors too - Goshenite - Hambergite
