Enhancing Your Gemstones

Looking at gemstones straight from the mine, they might be mistaken for pebbles or gravel.

Buyers Tip
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 (like the AGTA). The grading report should state that the gem shows no indication of enhancement by heat.

Part of the Process

Almost every ruby or sapphire you'll find has been heated, which is a practice that's been going on for centuries. Heating completes a process nature started, enhancing the gemstone to amazing colors of blue and red.

The jewelry industry recognizes heating as acceptable and expected processes. Heating is part of the polishing and finishing process for almost all rubies and sapphires. The heating of gemstones are practices accepted by the jewelry industry and the American Gem Trade Association (AGTA).
