According to Boyle, "You can clearly identify 95% of all gems with one simple test. Each gemstone has a unique RI that can be proof positive to identify the gems you have in your parcel." Match your information to the data on our Gemstones 101 pages or to the RI, birefringence, and other charts in Walter Schumann's book, Gemstones of the World.

Apr 21, 2017· The number of cleavage planes, and their orientations relative to each other, can be diagnostic of particular minerals. Minerals that display cleavage include: calcite, halite, fluorite, topaz, and galena. However, not all minerals have cleavage, such as quartz and pyrite. Minerals may have one, two, three, four, or six directions of cleavage.
