Review This Product
Great gems, just wish it had an info cardThese gemstones are perfect for practicing with the refractometer. The stones are so nice that once I get really good with my meter I'll turn these into jewelry. The stones are a good size and super easy to identify. My only qualm is that I wish there had been a reference card included that gave the RI values for each stone, with maybe a picture of the stone. I think that would have made this perfect. I still gave it 5 diamonds because I can actually use these stones after learning. May 09, 2013

This is a GREAT selection for learning.These stones are EXCELLENT! The colors are easy to identify and they match the item picture perfectly. The refractometer readings are right on the stated parameters and are a wonderful learning tool for the Refractometer. If you are serious about learning how to use a Refractometer these are a must have. These stones cleared up questions on Refractometer readings and usage better than the printed refractometer instructions. And there is no question as to the identity of the test stones.

Test setI am disappointed with this test set, and I am returning them. I thought the gems would be identified so I could check the accuracy of my Refractometer, and practice doing readings, but it is just unidentified stones. Thus, I can’t verify my Refractometer readings. April 29, 2013
