random poll about diamonds

i was just talking about this with a friend and decided the best way to find an answer is by asking you guys

Can you tell if a diamond is real vs fake (ie: cubic zirconia / crystal / etc)?

Personally, i have no idea ... if it's sparkly, i assume it's a diamond

Re: random poll about diamonds

nope, I have no idea! lol


I only knew my diamond was real when our jeweler insured it lol

Re: random poll about diamonds

I know, but only because my Mom is a jeweler and she trained her daughters at a young age

Re: random poll about diamonds

Usually...but one of my friends has an engagement ring made out of something that looks just like a diamond. It's might be moissanite, but I can't remember if that's the one. The only reason I even questioned if it was real was because it was like 2 carats, and a grad student bought this...I almost peed my pants .

Re: random poll about diamonds

I can tell. I have family member's who sold jewelry and they taught me.

Re: random poll about diamonds

I'd love to say I could, but no.

Re: random poll about diamonds

No idea... if i see something pretty and sparkly im always checking it out but now clue if its real or not

Re: random poll about diamonds

No clue in the world!!!!!!

yeah probably not ... but it's worth a shot

Re: random poll about diamonds

I have my own loop (or eye thingy...LOL) You are basically looking for cuts into the diamonds and inperfections.
-Look at the rock from the top and see how well the facets (cuts on top of the diamond) are joined. They should be sharp not rolled.
-While you’re looking at your stone under magnification, look into your stone to see if you detect any flaws (carbon, pinpoints, small cracks). These are typically clear indications it’s the real thing since it’s very hard to put inclusions in a fake.
- After examining the stone, focus in on the stamps inside the setting. A stamp of “10K, 14K, 18K, 585, 750, 900, 950, PT, Plat” indicates the setting is real gold or platinum which gives a better chance that the stone in it is real as well. While you’re looking at the interior of the ring, also look for any “C.Z.” stamps that would indicate the center stone is not a diamond.

The transparency test. If you flip the diamond in question upside down and place it over some newsprint and can clearly read through the stone, it’s not a diamond. (The problem with this test is some diamonds are cut shallow and can be read through.)

The fog test. This test I like a lot. Put the rock in front of your mouth and fog it like you would try to fog a mirror. If it stays fogged for 2-4 seconds, it’s a fake. A real diamond disperses the heat instantaneously so by the time you look at it, it has already cleared up. (A down fall to this test is 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.)

The weight test. The most popular of diamond simulants (fake) is a cubic zirconia. C.Z.’s weigh approximately 55% more than diamonds for the same shape and dimension. So if you have a carat or gram scale at your disposal you can see if the imposter tips the scales too much.

The U.V. test. A high percentage of diamonds fluorescence blue when put under an ultra violet light (black light). Since 99% of all fakes don’t, a positive identification of medium to strong blue would indicate a diamond. The bad news is if this method proves you have a diamond, it also proves your diamond is worth less. Diamonds with blue fluorescence are as much as 20% less valuable. Remember, lack of blue fluorescence doesn’t mean it’s a fake; it could just be a better quality diamond.
