Turquoise Grading is a process of evaluating, selecting, placing, and learning the various types of turquoise. Grading is the foundation of any gemstone. Selection of a turquoise stone is actually grading turquoise, comparing the merits of one stone against the merits of other stones.
Turquoise miners, lapidaries, artists, and buyers all grade and evaluate turquoise for their potential as either cutting rock, specimen rock or other uses.
The Turquoise Grading Contest is to showcase, grow, and celebrate the skill of grading turquoise.
