Adiamor Appraisal Document

Diamonds purchased through Adiamor are accompanied by their original certificate, also referred to as a Diamond Grading Report, Diamond Dossier®, or Diamond Quality Report. An appraisal document can also be included upon request. Adiamor provides free appraisals for all engagement rings, Design Your Own rings, and all gemstone jewelry valued over $1000. We do not provide appraisals for loose diamonds.

What is a Certificate?
A diamond certificate is prepared by an independent third party laboratory and verifies that a diamond is genuine and provides an evaluation of a diamond's characteristics. A certificate will contain a complete quality description of the diamond and will include information on shape, weight, color, clarity, fluorescence, measurements, proportions and overall finish.

Certificates and Diamond Grading Labs
Adiamor diamonds are graded by the two most reputable and respected laboratories in the industry, the Gemological Institute of America (GIA) and the American Gem Society Laboratories (AGSL). For your peace of mind, every loose diamond sold by Adiamor has been thoroughly analyzed and graded by either of these independent laboratories. These two laboratories have demonstrated a long history of strict, consistent, and unbiased diamond grading.

APPRAISAL AND CERTIFICATION DOCUMENTS
An appraisal is a document stating the approximate retail replacement value of an item and is usually necessary for insurance purposes. In case of loss, theft, or damage, your insurance company will use the appraisal to provide an equal replacement of your item. In addition, your insurance company will also calculate your premium based on the retail replacement value in the appraisal. At your request, Adiamor will provide a complimentary professional appraisal on diamond engagement ring purchases.

What's in our Appraisal?
Our appraisals are written and signed by our Gemology experts, so you can be sure that the item you purchased is of the absolute finest quality. The center stone is inspected under magnification to ensure it matches the accompanying laboratory certificate.
