Won't differentiate between genuine and lab. Only genuine and moiisanite
This item has been extremely accurate. I'm very happy with it. but if you're looking for something that can determine lab created this isn't it. those are far more expensive and I've heard not nearly 100% accurate.

Identifies white sapphires as diamond
Maybe I received a dud, the tester identified diamond and moissanite well enough but also identified white sapphire as diamond. I took to a jeweler to confirm, we tested a variety of their loose white sapphires, and the testerossa identified them as diamond every time. Cleaned the probe and let warm up per the instructions prior to every test but it made no difference. Ease of use is good, excellent ergonomics and portability is nice, but it failed in the most important metric which is accurate identification.

Above the Best
The Diamond tester worked flawlessly. I found it to be very reliable and have checked all types of jewelry with it, only one time did it come up Moissanite. This was probably due to the diamond having oil on it. Make sure the diamond and tip of tester are both clean. The tip of the tester is also spring loaded, making it more durable and less likely to bend form pressing the tip on the diamond hard. Very comfortable fit in my hand. Comes with rechargeable batteries which were dead upon arrival and a base for recharging the batteries. I put in 3 AAA regular batteries with the first tests and worked fine, then I put in the rechargeable batteries, charged them up in the base station and it worked fine also. The tester voice is clear, precise and understandable. You have both voice and visual recognition with the tester. One of 4 lights will also come on with the test. Green for Diamond, Blue for Moissanite, Pink for Sapphire and Red for Metal contact. It comes pre-program with english but has other languages that can be programed in. Made this purchase from amazon and shipping took about 3 days.

Item inaccurate! Wouldn't recommend it to anyone.
When i first got it out the box i seen it and i liked it ,i tested a diamond,and the pink light lit up that means that its not a diamond and its a sapphire.on accident the diamond tested touched pink light lit up saying that its a sapphire...the item was inaccurate didn't work:/

Gives false diamond indication. Some none diamonds test diamond. Very dissapointing
Very disappointing tester. The cheaper one test as good as this one.

The difference between moissanite & diamond.
I liked everything so far. I rated the accuracy as a 4 instead of a 5 because I am a novice & first time user of a gemstone tester. I did quite a bit of research and found this one that has diamond and moissanite separately & is able to detect the difference, so they say.

Terrible product
It was a Christmas gift and I missed the return window by two days. It Came in broken and I cant get ahold of anyone to replace it. My First one was ok until I had to replace the battery. The back broke off when I opened it. Its pretty fragile, and I couldn't get a response from the manufacture to replace this part. This is not a inexpensive item, and I definitely did not get my moneys worth either time.
