Formerly known as J Hyman & Co., Philadelphia Jewelry Appraisers is an independent appraiser and lab available for all of your needs. If you want peace of mind that your diamonds are natural or the colored stones are not treated, now you can find out. Appraisals include a high quality digital picture, complete description, GIA grading (he got his GG in 1992) and real values for retail replacement for obtaining insurance. Josh understands lab grown diamonds, all natural gemstones and Earth mined diamond qualities and markets. Most appraisals are done the same day or next and only cost $40 per item. This includes watches.
