Review: Get the warranty extension - I agree with the other 5 star review. For me this thing can still somewhat test setted diamond into rings as long as its in the right angle. However I havent tested a lab grown vs a natural yet. Not full proof, One dealer lab diamond past natural but his moisonite tester pass for moisonite couple of times. Turns out it was lab from gia. may purchase another lab tester for $400 to be extra sure. But this is great so that you wont get burnt that easily from unscrupulous people. Update stop working after 9 months. Workin with factory warranty. Get the 3 year extension only $20 bucks
Review: Inaccurate - Lost $2,500. Tested a pair of studs as natural that were labs. Quit working completely after warranty had expired.

### ⭐ Inaccurate

Lost $2,500. Tested a pair of studs as natural that were labs. Quit working completely after warranty had expired.

### ⭐⭐⭐⭐⭐ Why other reviewer left one star no explanation
*by L***O on August 9, 2019*

Seems to work fine. The only thing is when testing. The diamond has to be out of the ring otherwise if you put the diamond in the device face down still in the setting it may test as natural even though it in a lab grown. What is it about the device the other reviewer didnt like? Im curious. the other reviewer left 1 star. But why? Respond. Thanks
