About this Appraiser

Gemcorp, Inc. was founded in 1985 by Stephen Turner. There were no truly independent appraisers in the Atlanta area, and he decided it was time to fill that much needed niche.

Mr. Turner is a Graduate Gemologist from the Gemological Institute of America and has an extensive background in many aspects of the jewelry business. Just prior to starting Gemcorp, he was a manager and buyer for a five store, multi-million dollar retailer. While there, he also earned the prestigious title of Certified Gemologist-Appraiser from the American Gem Society (AGS). Mr. Turner remains affiliated with AGS to this day. In addition, Mr. Turner is a Senior Certified Member of the National Association of Jewelry Appraisers.

Over the years, and continuing to this day, specialty courses on appraising and gemology are a priority for the staff at Gemcorp. These have included programs from the International Society of Appraisers (ISA), the American Society of Appraisers (ASA), the National Association of Jewelry Appraisers (NAJA), the Accredited Gemologists Association (AGA), the Gemological Institute of America (GIA) and the Master Valuer Program.

Trained as a bench jeweler and also in minor watch repair, Mr. Turner also brings a unique perspective to the quality analysis of jewelry construction and condition. On numerous occasions, a potentially devastating loss has been prevented on new jewelry because he examines the entire ‘health’ of an item, as well as its value. In a time when we are all price conscious, there is a great temptation by merchants to cut corners on quality to offer lower prices. Our active lifestyles today are much harder on jewelry than times in the past. It is advisable to have any item that is regularly worn inspected by a professional bench jeweler every six months.

The ideal appraiser has a wealth of experience working across all levels of the marketplace. A retailer, who also happens to offer appraisals, is often subject to a narrow view and misses the ‘big picture’ required of a quality appraisal. For over 35 years, Mr. Turner has applied an educated view of fundamental valuation principles while studying commercial market behaviors. Count on your comprehensive valuation report to be easy to understand as it equips you with the true value of your gem's current worth. This Appraiser also appraises Crown of Light diamonds.

Knowledgable, Personable, Professional

The Appraisals are exactly what I needed for insurance. Everyone I interacted with at Gemcorp was courteous, professional, and knowledgeable. Mr. Turner is personable and obviously a well-credentialed expert. I found the appraisal process interesting to observe and Stephen shared information throughout the process. The appraisals provided are thoroughly documented and exactly what was needed to insure my jewelry. I received the appraisals within two days of the consultation. I would highly recommend Gemcorp and anticipate doing business with them in the future.

Expertise / Items Examined: Five men's rings, one with a 2.5 carat diamond, two with smaller diamonds. Three gold bracelets.

Great Service!

We had my wife's second wedding ring appraised for insurance purposes. Stephen did a great job - thoroughly and accurately appraising the value of the rings and returned the full report to us in a timely manner (about 1 week). I highly recommend his services.

Expertise / Items Examined: Diamond wedding ring.
