How do you tell if the stone in a ring a cz or a diamond?

Answer 1

Hi there

Diamonds almost always have impurities, i.e. small imperfections. As a first check get a x10 magnifier and look at the stone to see if there are any small specs, usually showing as tiny black bits. If you can see these then it is very likely you have a diamond. However the most clean of diamonds (very rare to find) will have no specs, so this is not a foolproof check but covers 99% of cases.

Another check is colour. Over 90% of diamonds sold for rings are not pure white (CZ is pure white). Check your stone against a known CZ stone and see if it is slightly duller or a very very slight hint of yellow. If it does have a very slight yellow compared with CZ then it is most likely a diamond - note the difference will be small but you should notice in clear daylight. Note again that this is not a foolproof check but it is another method to check.

Finally you can take your stone to a reputable jeweller that specialises in diamonds, but I would emphasise reputable, some may try to mislead you or simply don't know themselves and are not equipped or qualified to give advice.

There are also some good websites on diamonds, one that I can recommend is http://www.bestdiamonds.co.uk , there are others. Take a look and learn a little about diamonds before going to a jeweller, that way you are less likely to be misled.

Good luck, I hope this helps.

The only way is to get an expert to look at it through a jewel glass. Cz will also cut glass. Depending on the quality of cz some jewelers have trouble telling one from the other.

Answer 3

here's something interesting. a cubic zirconia is actually mor epleasing to the eye than a diamond. the quality of diamonds is based on how well the stone scatters light- that is what determines how brilliant a diamond is. cubic zirconias actually scatter light far better than diamonds and are thus more pleasing to the eye. the value of diamonds is completely artificial. De Beers essentially has monopolized the diamond industry and manipulated consumers into thinking that naturally mined diamonds are actually worth more than cubic zirconias and synthetically produced diamonds. A 1-carat diamond stone can cost more than 3,000 dollars. An industrial diamond used for glass cutting or other manufacturing tasks is worth less than 10 dollars. This artificial value of the diamond is due to the fact that the De Beers company has fooled most consumers into believing that natural diamonds are purer and shine more brilliantly thatn cubic zirconias- which is not true. They also contend that one's true love can only be conveyed by buying their loved one an expensive diamond- the De Beers company is effectively putting their own price on YOUR relationship- something only you can do (and something which should not involve any dollar amount) In fact, naturally mined diamonds contain more impurities than cubic zirconias and diamonds synthetically prepared ina laboratory. If I were you, I'd be glad to have a cubic zirconia. I know this had nothing to do with your question- but it's interesting to know.

Answer 4

although a cz is meant to be able to cut glass as well as a diamond, they are a little duller than a diamond and they are not set so well in the mount that they are in

Answer 5

Well just hit it with a stone or try to melt it.... real dimond are far harder then stones and have high melting point (though the shine of the diamond may be faded if u treat it like this)

Answer 6

Take it to a jeweler. They have a non-invasive tool that can tell in about a second. No damage to the stone.
But be careful what you wish for.

Answer 7

You can take it in to a jeweler and they can tell you. A real diamond will also cut glass.

Answer 8

Take it to a jeweler and ask.

But why not just be happy with what you have?

So what if it's a real diamond or not? Unless of course you plan to sell it, then you should have it appraised.

:)

Answer 9

A diamond will score glass.

Answer 10

Take it to a jewelery store and have it looked at. Also, diamond will cut glass.
