## Description

desertcart.com: Gem Indicator (PGI) Gem Tester : Arts, Crafts & Sewing

Review: Excellent way to ensure identifying Gem Stones. - Pretty easy to use. Works excellent.
Review: A good idea but HORIBLE quality control and reliability. Do Not Waste Your Money!!! - I used the device a couple of times before the thing gave me tip error. I treated it carefully after reading all the reviews, but it still broke. Called the seller and he had me send it into the manufacture, after being gone 2 months, I finally received the same device back with a new tip. GREAT... not been using it for less then a week and it is already acting up.. keeps saying testing and I never even touched the tip to a stone. Should of been made in the USA maybe it would work better. STAY AWAY unless you have 200+ to throw AWAY!!!!
