We have an in-house gemological laboratory

and our appraisals are performed by two participating appraisers. An added feature to our appraisals is that we include high definition digital photography that gets printed next to each item described; we also include a HD photomicrograph of major center stones, along with an actual plot showing their individual identifying characteristics.

Coffrin Jewelers offers loose gemstone certification and gemstone recutting. Our gemologists will perform individual loose gemstone reports on most gemstones, we can also have your gemstones identified and graded by GIA, the world's foremost gemological authority and independent laboratory.

We offer gemstone cutting, recutting and repolishing though our resources. Every type of gemstone behaves and wears differently and we know cutters who specialize in their types of gems and services.
