Is Proud to Present:

 Day-to-Day Gemstone Treatments and Their Identification
presented by

Daniel W. Campbell, BS,GG,FGA,CSM NAJA

There are many treatments that a wide variety of gems undergo. Some of these treatments are associated with particular gems. Others can be found in many types of stones. Some are permanent and some are not.

To detect some of these treatments, advanced techniques are required. However, many treatments can be identified with tools and observations that are readily available and these treatments turn up in gems virtually every day.

It's important that we pay attention to the gems we're identifying, grading and appraising. The presence of a particular treatment or treatments will have a significant effect on the conclusions we draw.
