a friend was married last week and I saw her ring just the other night and it was huge. Beautiful too. Her mother told me it was not diamond but something that looks like one, even under the glass. It starts with an 'm' I think. anyone know what I am talking about?
Sure... It's been this way for all the rings that I have seen, had and such... a real diamond will have a hole beneath the setting... or it may be set up high where the diamond doesn't touch the gold, silver or whatever. I don't if that is definately the rule, but it is an indication.
and I have a stone that's over a caret that doesn't and I can assure you it's real. Try the line trick if it's still unmounted...take a purple marker with you and draw a line on the paper. the CZ's and fakes you can see the line a diamond you can't...or at least what I've been told.
The only people who can authenticate a real diamond are certified gemologists specializing in jewelry. However, if you are browsing rings at a flea market and want to quickly assess whether a clear stone is probably glass, cubic zirconium, quartz, or leaded crystal, there are a few easy tests you can apply without any special equipment. These tests at least rule out recognizable imposters because they rely on the way a real diamond stone refracts light, conducts heat, and looks up-close.
If the gem in question is loose and unmounted, try placing it over printing. Diamonds refract so much light that they will not work as a magnifying glass and you would see no lines, circles, or letters through them. Other clear stones like glass or crystal will reveal the print clearly. A similar test uses a small light, such as the one that comes with your key ring. If you shine the light through the stone and cannot see it on the other side, but only a bright halo around the rim, it is more likely to be a true diamond.
Diamonds are also very good at conducting heat. Breathe on the surface of the stone and immediately check to see if it has fogged up. Again, quartz, glass, and cubic zirconium will stay hazy for a moment before the condensation dissipates, but you shouldn't be able to see any moisture on a true diamond. However, one rock, called moissanite, will also pass this test, so the best way is to get a complete thermal conductivity evaluation performed by a jeweler.
This subject fascinates me because in h.s. the girls were always wanting to check your jewelry "to see if it's REAL." It was a real fashion statement. I personally don't care if I have real diamonds or not. I can't tell the difference and it's interesting here you say only a professional can tell. I can't tell you how many girls were happy to point out my jewelry was "not real." It's real enough to me. =)
Now when it comes to metals I prefer real gold to "fake" because my skin gets irritated by the fake stuff now. I don't know why. Did so well for so many years.
Back to the thread topic: I'm glad you introduced me to another material that passes for diamonds. That's pretty neat!
On my mother's last Christmas she gave me a beautiful ruby and diamond bracelet. I wore it to work one day and one of my co-workers admired it and said, "Your bracelet isI beautiful if its real." I replied, "I don't really know. It never occurred to me to ask." I can assure you my mother always gave "real" jewelry.
