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

 |
| 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).
For a more detailed understanding of heating practices,
please read the AGTA's explanation of gemstone enhancements.
