if you know jewelry you can tell, real diamonds just have a great sparkle, if it is a cheap or bad real diamond, sometimes they look like a czWhen looking with the naked eye can a person tell the difference between a CZ and a diamond. If so, how?
Any individual whom is familiar with handling diamonds . Can tell you real from fake blindfolded just by the feel of the stone.Unlike natural diamonds, CZ are what I consider soul-less. They were lab created by man . Man will never perfect the work of god for they can not recreate spirit or the life force given to all things of nature. You will never see the perfection of a natural inclusion given to each diamond within a CZ . I consider it as their each individual soul. Or what gem print defines it as its fingerprint.CZ because they are man made their refraction is over processed compared to a natural diamonds perfection of the color range .When properly faceted under no condition could one read through a natural diamond ( one loose from a setting face down flat on its crown. in fact even rough cannot be read through at any given pavilion pointed edge. CZ is a complete giveaway to a trained eye . when properly faceted even they have fooled many people.Weight, specific gravity , all are different especially the touch , CZ does not absorb the oils from your skin.
Without question the quickest and most reliable method for authenticity would be an independent appraisal. This can be accomplished easily enough by looking under ';Appraisal (Jewelry)'; in your yellow pages. When you call to enquire about their services you want to ask three questions:
1.) Can you schedule an appointment or is it first come first served.
2.) Ask the fee; $35.00-$75.00 is considered a fair price.
3.) Ask if the jewelry will always be in your presence. If the appraiser says they will not evaluate the jewelry in front of you, find another appraiser.
If spending 50 bucks seems a little too steep to uncover the identity of your rock, you can head to your local jewelry store and ask their in-house gemologist to take a peek and give you their opinion. Since opinions are like belly buttons (everyone’s got one) understand that in a lot of these quick 30-second evaluations mistakes can be made. Especially since most jewelers won’t charge you for 30 seconds of their time. (Just like with independent appraisals, don’t let the merchandise out of your site.)
There are some less reliable methods you can try but there are no guarantees with these:
1. The old “If it will scratch glass it has to be a diamond.” Well, it is true that diamonds do scratch glass but so do a lot of the other fakes on the market. To boot, it’s possible to injure your rock even if it’s real during your hardness test.
2. 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.)
3. 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.)
4. 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.
5. 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.
6. Under the loop test. If you own some sort of magnifying lens, there are some things you can look for on the stone that might give away its identity:
A. 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.
B. Look at the girdle and see if it is faceted or frosty (a clear sign it’s a diamond) or waxy and slick (an indication it’s a fake).
C. 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.
D. 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.
Yes it can. I can very easily as I see diamonds every day.
The CZ has much more fire than diamonds. has a lower hardness (easier scratched and chipped) and when you look from the pavilion side and rock the stone, you see in CZ an orange flash, while in diamonds mostly blue and orange. Most easy this difference can be seen in diamonds with a round brilliant cut, but when you observe emerald cuts, it gets much more difficult !
When you put a CZ and a diamond on paper with text, with the table on the paper, you will see that a well cut diamond does not make you see any of the text below, while the CZ a little bit.
When you have some tools for examination :
Most people wearing CZ's choose big stones and they usually look like D IF's, while these are not so common and wear very serious price tags, especially in the over 3 Ct range. Big diamonds are set in platinum, or gold usually, in top quality finished jewelry pieces, while some CZ's are set in other metals and in lower cost jewelry.
Natural diamonds have some specific differences from synthetic CZ gems.
With a loupe you can see the facet junctions on diamond are sharper due to the higher hardness of diamond. The diamonds get scratched much more difficultly. Polish marks on diamonds run per facet in different directions, while on CZ they usually run all in same direction. Most CZ are also clean, non-included. Inclusions in CZ can be gas bubbles, which are unfound in natural diamonds. Under a UV lamp, a diamond can be inert, or be blue fluorescent (colorless diamonds !). A CZ will be greenish yellow to yellowish orange under longwave UV, yellow under shortwave UV. Easy to detect ! CZ gems will be heavier for the same size as a diamond : specific gravity of diamond is 3.52 while CZ's is 5.80.
Real diamonds are much more sparkly. Plus, you can also tell by the person wearing it...
