[QUOTE="RockRat, post: 491087, member: 12682"] To do with density i think. Another test i have seen done is the drop test. Topaz has a density of 3.49, Quartz 2.65. Drop a Topaz into an empty drinking glass from a few inches above the glass and it will jump out. Do the same with Quartz and it will stay in the glass. [/QUOTE]
