FOR DIAMONDS GEMSTONES & MINERALS

Guild Laboratories provides independent grading, identification and appraisal services for diamonds and gemstones. Colorless or fancy colored diamonds are graded by us to the same rigorous standards as those used at the Gemological Institute of America (GIA). Diamonds graded at Guild Laboratories strives to grade diamonds to the same standards as those at GIA Gem Laboratory. Determination of color origin for colored diamonds is not conducted in our facility. We can send the stones out for this advanced testing prior to conducting our appraisal examination.

We evaluate precious stones of all kinds, transparent and opaque, including jade, opal, ornamental stones, decorative art, and man-made gems. Most gemstones and their treatments if any are able to be identified at our facility. Advanced testing at an outside laboratory is warranted only in rare instances where a stone is not immediately identifiable. Our appraisal, identification, and grading documents conform to standards of wording established by the Laboratory Manual Harmonization Committee (LMHC).
