Some places to sell gemstones include auction houses, independent jewelry stores, pawn or antique shops, estate dealers and private buyers. Searching online auction listings can make it easier to estimate the value of similar gemstones.
To determine the value of a specific gemstone, consider having it appraised by a jeweler. They often charge a fee to appraise the piece. In general, transparent gemstones are typically worth more than opaque ones, and strongly colored gemstones are worth more than dull-colored stones. Pieces that were made or signed by famous makers, or those with a distinct style from certain historical periods, are typically worth more.
