DIAMONDS ~ REAL OR FAKE ???
I've had a number of Ladies e-mail me asking how to spot the difference between a real Diamond & a Fake Diamond.
It can be difficult to tell sometimes. Some Sellers sell Cubic Zirconias & the like under the description of Diamonds so be wary who you buy from & read the small print on the listing.
I personally have a professional electronic Diamond Tester which works by testing the heat of the Stone. Diamonds have a higher temperature than other Stones (I found that quite interesting).
Anyway to get on with it I found some rather interesting info' on other ways to ensure you're getting what was advertised...here goes...
- If you have access to a diamond tester, you can test for diamonds vs. simulants.
- Check with your Local Jeweller, not the chain Stores ie Prouds etc but a Jeweller Shop which has an actual Jeweller working in it.
- The transparency test. Flip your diamond upside down and place it over some newsprint. If you can clearly read through the stone, it's not a diamond. (Beware, some low cut diamonds or stones such as emeralds can be read through.)
- The fog test. Put your diamond in front of your mouth and fog it like you would fog a mirror. If it stays fogged for 2-4 seconds, it's a fake. A real diamond will disperse the heat instantaneously so by the time you look at it, it has already cleared up. Oil and dirt on the stone can affect 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 glued together.
- Test for weight. The most popular diamond simulant (fake) is a cubic zirconia. C.Z.'s will weigh approximately 55% more than diamonds for the same shape and size. Use a carat or gram scale to see if the impostor tips the scales too much.
- The U.V. test. Many diamonds will show fluorescence of blue if put under an ultra violet light or black light. 99% of all fakes don't do this; so, a positive identification of medium to strong blue would indicate a diamond. Diamonds with blue fluorescence can be as much as 20% less valuable; however, lack of blue fluorescence doesn't mean it's a fake; it could be a better quality diamond.
- The under the loop test. With a magnifying lens, there are some things you can look for on the stone that might give away its identity:
- Look at your diamond from the top and see how the facets (the cuts on top of the diamond) are joined. They should be sharp but not rolled.
- Is the girdle faceted or frosty (yes, then it's a diamond) or waxy and slick (yes, then it's a fake.)
- Under magnification, look into your diamond for flaws (carbon, pinpoints, small cracks.) It's very hard to put inclusions into a fake.
- Look at the stamps inside the setting. A stamp of "9ct, 18ct, 22ct 585, 750, 900, 950, PT, Plat" indicates the setting is real gold or platinum. This gives a better chance that the stone in it is real as well. Look for any "C.Z." stamps. This will tell you the center stone is not a diamond.
Hope this was of some Help....Cheers Karen
