👉 Will it test as a diamond?

If we test how moissanite conducts heat, we might get a wrong result: it will test as a diamond. But by checking the electric conduction, we will find out its moissanite and not a diamond. Then, same as with natural and lab-grown diamonds, we can send the moissanite to a lab and test how it reacts to UV rays.

👉 Will moissanite test as a diamond?

It has a beautiful diamond-like appearance and durability but costs 90% less than the average diamond. It conducts heat very similar to a diamond which is the main test used in a diamond tester, allowing for most moissanite to oftentimes pass as a diamond. Typically, a diamond tester will register both moissanite and diamond as a diamond!

Test it A quick way to tell a CZ from a Diamond is to take it to a Jeweler and have them Diamond Test it! Diamond Testers will test the Hardness of the Stone and determine whether it’s a Diamond or not. Anything that makes that crazy “ honking goose noise ” is not a Diamond.

A diamond's facet edges will usually look incredibly sharp and precise. Look at the color of the light as it enters and escapes the surface of the stone. If you turn both a diamond and a CZ upside down, the bottom of a diamond will give off the entire rainbow of color reflections, whereas CZs usually have more exclusively orange and blue flashes.

If you want to know if your diamond is a real natural stone, you can do five tests at home. These can help distinguish between diamonds, cubic zirconia (CZ), and artificial diamonds such as moissanite. The last three tests work better if you have a loose stone. If the stone fails all five tests, your diamond is likely fake.

CZ has an RI of 2.15 – 2.18, while a diamond’s RI is higher at 2.42. Although both stones sparkle, a diamond has a greater depth of brilliance which the CZ cannot match. A CZ cannot hold light as a diamond does. Without doubt, a diamond’s brilliance is one of a kind which is part of its timeless allure..

Another easy test is to breathe on the stone. Diamonds don’t retain heat, so they’ll become almost instantly clear again. Cubic zirconia tends to retain heat longer than a diamond and will stay cloudy. If you have access to a black light, take a look at the diamond beneath it.

This test is quite quick to do and you will only need an ultraviolet or black light and a diamond. Turn off the lights and hold the stone in front of the black light. If you see a medium to strong color of blue, you can rest assured that you’re holding a real diamond.

Stamps inside the setting indicating real gold or platinum (10K, 14K, 18K, 585, 750, 900, 950, PT, Plat) are a good sign, while a "C.Z." stamp will give away that the center stone is not a real diamond. C.Z. stands for Cubic Zirconia, which is a kind of synthetic diamond. 3 Use a jeweler's loupe to inspect the diamond.

If a syn cz or zircon are testing as diamond on a dia tester, the tester’s sensitivity is set too high, the probe is damaged or possibly a weak battery. Try the tester out on a known diamond and

Check the markings on the inside or back of your jewelry. If they say 10K, 14K, or 18K, they are solid gold and you most likely have a real diamond. If the jewelry says C.Z., it is cubic zirconia. Diamonds are sometimes set in jewelry that is not solid gold, so this cannot tell you definitively if your piece is a diamond or not.

For the fog test, hold the diamond or ring between two fingers and breath on it with a puff of air. A light fog will form on the diamond because of the moisture and heat in your breath. If the fog dissipates right away, the diamond is real. If it takes several seconds for the fog to disperse, it is likely a fake diamond.
