Many stones are treated to mask the natural imperfections. Emeralds rate a solid 7.5 to 8 on the Mohs Scale, making them an excellent choice for jewelry.
Synthetic emeralds (developed by Carroll Chatham in the 1930's) have fewer imperfections and are very hard to distinguish from natural emeralds. Emeralds belong the beryl group of stones which also includes aquamarines, morganite, and chrysoberyl).

Many of these tiny imperfections are removed when the diamond is shaped. Today cutters also have the option of using an enhancement technique that focuses tiny beams of laser light at imperfections and vaporizes them.

These imperfections may be small and unnoticeable or large and distinct. The number and visibility of marks on its surface determines the quality of a pearl. Lustre can drown out pearl blemishes the same way brilliance can drown out diamond flaws.
