Peter has a well equipped Gem Lab to identify most gems. The most modern of microscopes and two complete diamond color master sets enable us to accurately grade any diamond. Thirty years of education and experience has sharpened our skills. We know when to advise our client that it is in their best interest to go to the GIA or AGTA for certification. There are times when official documents can make a significant difference in the value of a stone. We will be honest enough to tell you.
