The primary issue with topaz that must be remembered at the bench is its one perfect cleavage direction. Hammering or putting pressure on a topaz runs the risk of cleaving the stone into pieces. Routine stone tightening on a prong set topaz can result in cleaving the stone. Setting a topaz in prongs presents a greater risk than tightening. To minimize the risk, avoid alloys that are very hard, as well as overly thick prongs. Cut stone seats with care and smooth away any burrs left by tools.

Topaz is commonly yellow, orange, or brown in color. Pink topaz is a lesser-known color. "Imperial" topaz is a pink-orange color that is reminiscent of zinfandel wine. Colorless topaz is an historic diamond imitation. Topaz is found in many areas around the world, with South America and Sri Lanka leading production.
