The following information is intended to help both sellers and buyers evaluate quartz crystal with a more universal grading process.
Clarity is the degree of transparency of the crystal point or points on a cluster.
A crystal clarity can range from very milky to water clear. Most crystals have milky bases where they were or are attached to the matrix and will gradually be more clear as they terminate at the point. Some points also have what looks like sleet on one or more of the sides or faces which can distract, or sometimes enhance, the overall quality. Shine is a measure of the brilliance in the points. Some points have a film or etching on the sides and faces that reduce the overall brilliance of an otherwise clear crystal.
