Hello List,

Just started to catch up on some of the recent posts
to the List, and came across the thread about
Tsavorites. I saw this auction on eBay, and I said to
myself, "Good grief, 'Tsavorite Tektites'? This is
really going to start a firestorm on the List!"

But instead, I see 'Tsavorite Tektites' being
discussed as if it were an accepted name. I must say
that I am very disappointed. I can't imagine that any
mineralogist, or any dealer/collector of Tsavorite
garnets, or any dealer/collector of tektites would sit
still for such a misuse of this very specific term.

I suppose you could make a case for the phrase
"Tsavorite-green" or "Tsavorite green-colored" but
using a mineral name as a place name is not only
risking confusion, but risking being accused of a
scam.

For those that have an interest in this material, and
certainly before making a purchase, I would suggest
contacting the GIA in San Diego to see if they have an
analysis of this material. (They are very familiar
with another "green glass" used in jewelry that is
made from a melting process that uses Mt. St. Helens
volcanic ash!!;-)

I've reread the auction and tend to agree with Thomas
Webb; at least I hope this is what the auction Seller
intended to convey in his Description.

Greetings Robert and list

Seems this came up last year and the one seller, on
their website said that the analysis was a volcanic in
origin, but still sold them as tektites or moldavites.

  Hello Thomas & list.=20

  There are Tsavorite GARNETS and what are called
Tsavorites which are being referred to as tektites.

  Both are found in the same region but are two
different things.

  The Garnet formed in matrix and has a crystaline
structure. The green glassy stones do not display any
crystal-structure and do not appear to have formed
within any type of matrix.

  One ebay seller specifically mentions that he is
selling Tsavorite Tektite which is not to be mistaken
for Tsavorite Garnet.

  The common naming and coloration shared by both
materials creates confusion between the two.

  One of these two types of similar things contain
tiny air-bubbles...

  Guess which one.......it's not the Garnet...

  Hello list,
  The guy with the ebay ad does not call his stone
Tsavorite. He only uses this term to describe the
COLOR of the stone he is selling. He even goes on to
say that Tsavorite is a green garnet, which is
correct.
=
 He does however call the stone a tektite. Perhaps
someone can clarify the truth or non-truth of this
proclamation.
  My best,
  Thomas H. Webb
