Nearly all gemstones available on the open market have been enhanced. Those that have not been enhanced are very rare and command extravagant prices. Before buying a gemstone that has not been enhanced ask to see a grading report, preferably one from a well-known gemstone grading lab. The grading report should state that the gem shows no indication of enhancement by heat.

Unpolished gemstones are typically very rough. Looking at gemstones straight from the mine, they might be mistaken for pebbles or gravel.
