Fake diamonds or real ones?

One suggestion was to take a piece of paper and mark it with a dot. Lay the paper over a light table and place the diamond flat side down over the dot. If you can clearly see the dot it is a fake. A real diamond would break up the image.

The fakes have gotten very good and it is virtually impossible for an amateur to tell the difference. Look at Moissanite
Even standard diamond testers cannot tell the difference.
Be Careful! Don’t invest a lot of money. If possible, have one from your grandmother, mother, or other relative reset into your own ring and then pass it down to the next generation. The sentiment will have a lot more meaning than the value of the carbon.

@Lupin I am not if you are a diamonds expert or not, but I wanted to ask if there is an issue that comes with synthetic diamonds that are just like real diamonds?

I always thought that only real diamonds have the hole in the back of the metal, and fake ones don’t.

Bring it to a jeweler.

@sap82 No I am not a jeweler but I have seen a moissanite stone.
A few years ago an idiot, big-timer acquaintance of mine bought one of them for his fiance and let her think it was real. He spent something like $1500 for 3? 5? carats and had it set. It looked gorgeous. She was so happy and showed it off to everyone. One day he came home and noticed she was not wearing it. She had taken the ring to a jeweler to be appraised since it was obviously so expensive and should be insured.
He quickly went to the jeweler, who immediately figured it out the situation, and asked if “anything could be done”. “Why Certainly! ” He ended up buying a real diamond for $12,000 to match the fake one. He never told his now wife.
He keeps the fake one on his desk at work as a reminder of his (and society’s) stupidity.

@Lupin

Moissanites are rather easily identifiable under UV because they have a green or yellowish fluorescence.

@sap82

You are referring to an effect called birefringence, diamonds as well as imitations are subject to it, imitations much more so tho. Birefringence is not a safe indicator if a stone is real, because it can be countered with appropriate cutting of an (imitation) stone along it’s optical axis.

@Taosan That’s a good trick. I’ll try it with UV-A,B,C next time I visit the guy.

@Lupin

Kinda sucks whipping out the UV flashlight at Jared’s tho lol

@TaoSan I was just looking around and did not see any mention of the different fluorescence. C3/Cree makes a detector for $500 to identify moissanite. If it was as simple as shining a 4 watt blacklight bulb, the unit should be selling for $25. I see that the Gemological Institiute of America is making a unit to detect the difference .
I wonder how many of those “Oh he went to J-ds!” girls are actually wearing moissanite.
I say stick with the family jewels (so to speak). The sentiment is more important.

@Lupin

Yeah, I just googled around, you get better results if you use silicone carbide which is what they are basically…

Thanks for all the suggestion. Got to know many things which i was not aware of…thanks again
