Radiant Gemological Services, servicing Metro Detroit and Southeastern Michigan, is an independent fine jewelry appraiser providing independent appraisals, evaluations, and identification of diamond and colored stones.

All appraisals are completed by appointment, by a G.I.A. graduate Gemologist, adhering to the Gemological Institute of America's grading standards and procedures. The value method used conforms to the methodology of the National Association of Jewelry Appraisers.

All of our appraisals are performed while you wait helping to save you time, and giving you piece of mind that your jewelry will never leave your site or our office.

Socially Responsible Appraising

While we're accountable for your fine jewelry, we also believe in being accountable for the community in which we serve and live. That's why a portion of our services are donated to charitable organizations such as World Vision and Blessings in a Backpack. Allowing us to serve you with the highest quality GIA appraisals also allows us to "pay it forward" to others in need. Thank You.

Retail Replacement Value:

A retail replacement value is a value assigned to an item which would be comparable to the price assigned at a retail jewelry store. This value is calculated using current pricing guides and averages of current marketing prices. This value does not consider bulk purchase discounts and is based on the premise of duplicating the item one time.

Estate Value (Fair Market Value):

The price at which the item would be sold between a willing seller and a willing buyer. This value does not consider antiquity, sentimental value, workmanship or a retail markup, but rather the cost of raw materials alone. Workmanship and antiquity is considered only when the pieces was created by a well-known designer or design house. This value is based on industry averages and knowledge of out estate evaluation expertise.
