Element47,
Refractometer is useless for diamonds as Diamonds are above the upper limit of the scope. For all those who depend on a Diamond Detector to seperate out Moissanties and Diamonds: Don't! Lots of CVD coated Mossy's on the market. that's Diamond coated Mossy's that will fool the Best of Diamond detectors. On loose stones, I have never seen a CVD Mossy that is coated on the bottom or Pavillion but not saying they don't exist. Understand that Mossy's weight about 90% of what a diamond weights and are Double Refractive. The formula to determine diamond weight is Dia2 x depthx.0061 which will get you real close. If it is light, it's probally not a diamond.
I often have to seperate out CZ's & Mossy from Diamonds oon 100+ carat lots. Yes, HF is Super nasty stuff and you got to have lots of RESPECT for it. Yes, we have the GEL, a approved Enclosure, correct gloves and have had OSHA in reviewing our procedures. But I think I am going to order a kit anyway as you can't be too careful.
Thanks 4 Metals for the link!
