The gold and diamond tester kit arrived complete quite quickly. The inclusion of a magnet would have been helpful as an additional item for testing and confiming whether a piece of jewelry might not be gold and might just be a gold plated magnetic metal necklace or ring.

This is just as described. Not the best quality on the diamond tester, but it works great! Very happy with my purchase!

After an elderly relative passed, my brothers and I spent a lot of time cleaning out her house. I got this set to help expedite going through her jewelry to see what was real and what was costume. This was very helpful. I would recommend.
