Ways to inform if your diamond is genuine or phony.

1) Never look at a loose diamond on a white jewelry experts' tray. Constantly look at it on a piece of paper or printed material. If the diamond is genuine, you will not have the ability to check out the newsprint through the elements; if the diamond is fake, it's just like looking through, well, glass.

2) Among the best test is thermal conductivity. Diamonds are exceptionally excellent conductors of heat and most jewelers have a small instrument that can determine this. No other product will match a diamond in this test.

If it remains misted for two to 4 seconds, its a phony. A real diamond distributes the heat instantly so by the time you look at it, it has actually already cleared up. (Often oil and dirt on the stone can effect its reliability and the test is not accurate at all on doublets where the top of the stone is diamond and the bottom is cubic zirconia epoxied together.).

4) Under the loop test. If you own some sort of magnifying lens, there are some things you can search for on the stone that might give away its identity:.

A. Look at the rock from the top and see how well the aspects (cuts on top of the diamond) are joined. They need to be sharp not rolled.

B. Take a look at the girdle and see if it is faceted or wintry (a clear indication its a diamond) or waxy and slick (a sign its a fake).

C. While youre taking a look at your stone under magnification, check out your stone to see if you find any flaws (carbon, determines, small fractures). These are typically clear signs its the genuine thing since its really tough to put inclusions in a phony.

D. After analyzing the stone, focus in on the stamps inside the setting. A stamp of ESTA "10K, 14K, 18K, 585, 750, 900, 950, PT, Plat" shows the setting is genuine gold or platinum which gives a much better opportunity that the stone in it is genuine too. While youare taking a look at the interior of the ring, likewise search for any "C.Z." stamps that would show the center stone is not a diamond.
