What is Tavolite?

Hello,

I'm a mewbe to the group. I am hoping for a little help.

I ran across an ad that has a Tavolite ring and necklace. The stone
looked
nice so I thought I would see what it was.

Well Google gives me back only 4 or 5 hits! Meta and Dog pile are no help
either.

I know this is not some just recently discoverd new mineral or gem, so
what
is it?

Thanks for your help.

Yes your spelling is incorrect. Tavalite is not a type of stone, it is a
brand name. It is a CZ with a light film coating to make it iridescent
(sp?). More info can be found here http://www.tavalite.net/

Thanks, Brian, for bringing this to us. I'd wondered whether these were
something of the sort, but with just the word tavolite to go on, hadn't found
much, so I was just guessing. I've little doubt that you've found what the
original poster was looking for.

According to the web site you mention, they also do this using natural white
topaz as the base stone on which they deposit the coating. The publicity and
articles they quoted seem to focus more on the topaz product than the C.Z. one,
with the prime exception of the article in Gems and Gemology.

The coating type appears to be a fairly standard technology, vapor deposition
coating, and the product appears, at least the ones done in topaz, to be very
similar to another product I've seen the last few years, sold as "mystic topaz".

The coatings applied this way can vary a lot in appearance. In what's done
here, there is first the actual color of the coating, which seems blue to
green so far as I can tell in the web site photos. But what makes them
especially interesting is that these thin coatings also give interference
colors, which is the "irridescent" look, and that range of colors will depend on
the light source it's seen under, and the viewing angle of the veiwer relative
to both the stone surfaces and the light source.
