A great place to shop for jewelry making tools and supplies

This product is easy to use if you follow the instructions provided. It can distinguish between fake diamonds, metals and diamonds. I got the same readings with moissanite as with diamond. So I need a different probe for that. In general, I like to use it for small diamonds/moissanite.

Pros
  • Professional Diamond Selector II will tell if a diamond is real or fake
Cons
  • Zero

Pros
  • Jewelry making tools and supplies
Cons
  • Questionable purchase for seniors
