Dear Friends,
In my country a lot of people use CZ as a engagement ring.
but CZ can be dulled by contact with soap, make-up and the natural oils of finger.
Any new syntehtics stone can be replace the CZ, they like to buy CZ because of cheap and fire.
Thanks and best regards.

Hi,
Perhaps heated natural Zircon,I have only ever had one batch of small stone done this way but they are very bright and can be made quite cheap. One problem I think Zircon treatment can be slightly unstable and odd stones can regain some of the redish/honey tint over time,most are okay. Just a thought?

Cheers Andrew

Both the facets on CZ and natural zircon show distinct wear over time. But you know, if that happens, they can be inexpensively replaced.
Some people have said CZ clouds over time. Not really, it gets dirty as a result of its surface tension. Remedy: Clean it.

Thanks Barbra,
I take 10 pcs of used CZ, all can be clean up.
Only some stone the facet wear due to hardness.
The sentence i read from (Guide to GEMS, written by Cally oldershaw) page 192 .CZ can be dulled by contact with soap, make-up, and the natural oils from finger. was incorrect.
thanks for your guide.

CZ is pretty good but it looks a lot better if you keep it clean. Use a soft brush like a toothbrush and a cleaning solution like dishwashing soap or glass cleaner that breaks the grease bond and you'll be amazed at how long they will stay loooking like new. Be sure to clean the back side of the stone because that's where your brightness is coming from.

Hi Teh Hong Kee.
Neil' suggestion is tight on the money!

The quote above is correct in the sense that CZ (and diamond!) will easily be coated by soap, make-up and natural oils. The greasy coating makes diamonds and cz's look dull, chalky and lifeless. Anything that will cut through grease cleans them up: Ammonia, Windex, Mr. Clean, etc.
