Some of our items are accompanied by a lab report, but not all. It will be clearly stated if there is a report with a particular item. We do not go out of our way to remove diamonds from their settings to obtain GIA reports unless we feel it is absolutely necessary as we like to maintain the original quality of our pieces. We guarantee our grading and grade our diamonds according to GIA standards.

All our diamond grading is done by GIA graduate gemologists and at least one gemologists look at each piece. 

Gemma Amans uses its knowledge to date each piece based on materials, hallmarks/signatures, overall style and cultural context. While dating and authenticity are not a formal science, we determine them to the best of our ability based on our knowledge, experience and resources. Some of our pieces are mounted in a way that makes it difficult to determine a precise stone’s grading. Diamonds and colored gemstones that cannot be removed from their antiques settings without harm to the piece are evaluated in their mountings using industry-standard measurements and formulas. Unless certified by an independent lab, stone gradings are done by us. 

Jewelry descriptions and all carat weights stated represent approximates. 

All diamonds shown on our website are natural, untreated diamonds. 

We cannot guarantee that the color you see matches the item color, as the display of color depends, in part, upon the type of computer monitor used to observe the image.
