Jewellery is my occasional afternoon hobby Wayne
I just love jewellery
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.
Looking closely at the specks, ridges, and facets can also give you a clue into the identity of your gem. Diamonds do have inclusions, tiny bits of other minerals that got crushed into the diamond while it formed deep under the earth. However, if the facets have worn or rounded edges, bubbles, or if the gem looks rippled or pitted, it is probably glass. Those gems that are perfectly clear, with absolutely no inclusions, are probably quartz.
Finally, some common sense measures can prevent you from getting pressured to purchase a gem that turns out to be something other than a diamond. It shouldn't be ridiculously inexpensive, or you'll get what you pay for. It also will usually be mounted in an "open back" setting, which means that you can see around the rear of the gem and the back surface isn't coated with any silvery substance. Although it's true that diamonds are the hardest organic substance on earth, the infamous test of scratching diamonds across glass or metal might just give you a damaged diamond.
Even many gemologists cannot distinguish "real" diamonds from cultured diamonds. Cultured diamonds have been artificially manmade in a laboratory, not mined from mountains, yet they are chemically identical to those diamonds. Some companies are developing new kinds of identification methods for those who would like to purchase a mined diamond or for those that prefer a cultured one.
Even experts cannot tell a diamond from glass or quartz without examining.
I know wealthy people who still buy the ones from Thailand and China! Haha. They come back with a new Tag or Breitling and a cheap Armani dress-shirt after every business trip...they love it

Yep, that's women for youThe ring seemed more important than anything else.
WTF!!!
Cars are different because of engineering, utilitarian, and reliability factors.But WayneL, would drive a BMW or a Holden...
I remember that add for the new Commodore and how apparently experts rated it better than the BMW, blah blah blah...
And i remember thinking to myself, but its a Commodore!
Sure, both are rear wheel drives... have 4 wheels and get you from A to Z... but heck, one is a piece of engineer brilliance, the other... well... maybe the new ones are better, but my past experience of commodores and their handling, center of gravity, not to mention reliability... well, i might be wrong
I must admit, there are some watches with price tags that rival that of a reasonbly priced car which I'd gladly endulge myself of (if I didn't need my reasonbly priced car!)...but things like this are symbolic to me of what I've achieved...I really couldn't give two hoots whether anyone else realises its real or from Thailand. In fact I find that displays of real wealth can be bothersom if you intend on having real and normal friends.

Made what exactly?Those that wear real couldnt care less what people think and pay for the quality and as a symbol that they've made it.
Made what exactly?
I can point out tons of people who look like they've "made it", but in reality they are just deep in debt. What they've "made" is a whacking great hole in their cashflow.
According the the book "the millionaire nextdoor", those that have "made it" financially are least likely to have outward signs of wealth.
I've often wondered this. I admire the craftsmanship and art that goes into making an individually designed piece, and I do appreciate it on women tastefully and moderately applied.
But is it important that it is true diamonds and not cubic zirconia etc? Why?
Why not costume jewelery that looks the same to all but an expert?
I remember standing in a line at an airport and the guy behind me taking every opportunity to shove his Rolex in my face. Obviously the chap had self worth issues that he felt could only be solved by ostentatious displays of wealth.
As an ardent antisnob, I find it a bit puzzling.
