Purity Testing Kit for Diamonds Gemstones Moissanites Gold Silver and Platinum Jewelry Electronic Digital Diamond Tester Machine JSP GTE

I couldn’t be happier with this Purity Testing Kit! It has everything I need to test diamonds, gemstones, and metals like gold, silver, and platinum. The kit is comprehensive, with a digital diamond tester, various acid solutions, and clear instructions, making it easy to use even for a beginner.The real highlight, though, is the customer service. When the tip on my diamond tester broke, I reached out about the warranty, and they responded promptly and professionally. True to their word, they sent a replacement right away, and it arrived quickly. The company truly stands behind their product, and that gives me so much confidence in using this kit.This kit is reliable, accurate, and backed by excellent customer support. Highly recommended for anyone who needs a quality testing solution for jewelry and precious metals!

I bought this to test my metal detecting treasures, mainly gold and silver jewelry. It arrived quickly and well packaged. I tested several types of gold and some silver and it did fine. I had some 10 k gold that didn’t dissolve fast in the 14 k acid but instantly in 18k acid so maybe the 14 acid is old or I’m doing it wrong. Haven’t tried the diamond tester yet, but will. In all, happy with my purchase so far. Thanks 😊

For the price, this kit is decent. The acids, diamond tester, and loupe make it worth it. Even if the last two are of cheaper quality, they get the job done. As someone just starting out with jewelry, I’d recommend for beginners.However, the stone is crap. Other reviews mention that the acids don’t work, but I’d bet my money that it’s really the fact that the testing stone is actually glass. It doesn’t scratch well, and tests awfully. If you’re looking for an alternative, I found a real stone one under the SE brand for less than $10. It’s tiny, but tests miles better than the glass they provide in this one.

Great starter kit. I think it needs a storage case tho, apart from that it’s great

This test kit gave me undeniable results ! Bangles were 14 k ! Glad I bought test ! kit !

This has been an amazing tool for mine and my husband's hobbies. So easy and care free

Unfortunately what I intended to buy this for which is the drops for metal testing, they do not work as expected. I am unsure if they are expired or if they just don’t work properly but they do not give me the results I was looking for and instead the metals start to almost float once the drops are placed on. I have tried this with jewelry I know is pure gold and not questionable yet I still came across this issue :( looked to get a partial refund at least considering I like the microscope and diamond tester it came with but it didn’t give me the option to.

I've tried everything to get the diamond tester to work. I've even went on YouTube and got the exact directions for it and it still doesn't work. All it does is beep. I have turned it all the way down and it still doesn't work correctly. The metal testing seems to work. I have tested it with gold and silver. The gold definitely works correctly. Silver acid ate through the cap so make sure you store it up right

Great kit and fast delivery

Exactly as advertised, very happy.

Un pochino baracchetta

Nice kit but missing the 9k test

Delivery was a little slow but the product worked great
