Another Tsavorite

The color of tsavorite is believed to be due to vanadium, at times with a trace of chromium.[/i] [my emphasis]

[...]


Other net sources also quote V and/or Cr; the Palagems one seemed the most authoritative

Richard Hughes knows his gemology but probably the most recent in-depth study of gem garnets, by Carol M. Stockton and the late D. Vincent Manson, both GIA researchers, concludes that "...both vanadium and chromium are usually responsible for the green in grossular garnets" [tsavorite/tsavolite]. In their paper "Gem-Quality Grossular Garnets" [Gems & Gemology, Winter, 1982] they write that similar vanadium-chromium relationship results have been reported by several other prominent researchers.

"An exception to this relationship between vanadium, chromium and green coloration apparently exists in grossulars that are colored principally or solely by Cr2O3," saying they had none to test and could not say how their color compares with the V-Cr stones.

It''s interesting that V seems to be the sole cause of color-change in pyrope-spessartite garnets.

omc,
The design is vieux Mauboussin, right?

Yes - about 1960. I have no idea if they made earrings - but since we have a ring... I felt free to copy.

 

[Harriet]

Oh, no. I wasn''t referring to ''copying.'' I was referring to our earlier exchange about the new Mauboussin.

 

[oldmancoyote]

Ah - got you. Well, I think the ring is a very well made piece - but I''ve only seen the modern "cheap" Mauboussin stuff in photos (SignedPieces seems to have quite a few bits, which is not surprising given your feedback on quality)

 

[Harriet]

[Double post.]

 

[Harriet]

Signed Pieces has Mauboussin items already?! That''s quick, given that Mauboussin recently re-launched here. May we see your good old Mauboussin?

 

[oldmancoyote]

Sorry Harriet - my bad. Nine Treasures has plenty of it on eBay, and for some reason I though it was SP.

Anyhow - here she (he? it?) is - in all her glory and dust...

 

[Harriet]

Thanks. What other treasures are in your trove?

 

[oldmancoyote]

And on DW''s hand. Which really makes me think I should be looking for a pair of sapphires, rather than tsavorites, but she says she likes green...

What the heck - a pair of sapphires AND a pair of tsavorites. A man can dream, surely.

Whoops - cross post. You are very welcome :bow:

Ah, well, now, that would be telling, wouldn''t it?
(hint: google "the coyote''s den" + the fallen-from-glory jeweller - this will tell you where it all is... apologies in advance for the cloak-and-dagger, plus the first photos aren''t that good, but I do feel somewhat exposed posting too many photos on PS)

 

[Harriet]

There''s nothing. I know a former crown jeweller (Asprey). Won''t it be funny if you''re one and the same?

I wish... Not even a poor relative.

Apologies for the mess on the link; photos are on that site, on the thread called "The Coyote''s Den". Google only finds the print version which has no images embedded. Bummer.

i think you have seen this before-the stones were all bought on line and were represented by pics of the stones before the sale-i was able to id the stones at time of sale and all stones were sold w/moneyback guarantee-all stones have been appr-all homework done-so what i end up with is a pendent-tsavorite-with good represented stones at a suprising good value-just my 2 cents...

 

[LD]

OMC - will you please adopt me so I can play with my new Mummy''s jewellery? That sapphire is heart stoppingly gorgeous! I''ve got to say that of all your DW''s jewellery I now have a new favourite (the old favourite being a little pink wedding number that collects dust)!

Harriet, I have been priviledged to see some of OMC''s stunning collection online on another forum and I can tell you THE MAN HAS EXPENSIVE TASTE!

 

[oldmancoyote]

LovingDiamonds - consider yourself adopted in whichever role you like: sister, aunt, cousin, daughter... (DW may put a few conditions on "second wife"). Coyotes like large families. And my email is... on the other forum.

Oh yeah!

I am now officially LovingDiamondsCoyote and Dad is going to let me play with all Mom''s jewellery!

 

[Harriet]

How do I hunt down this Coyote?

 

[coatimundi_org]

I wanna see too! how? HOW?

 

[oldmancoyote]

Hum... let''s see... if you Google "The coyote''s den" + Cartier, that should get you there.

Harriet and Coati - if you don''t mind a large family, you are welcome to join!

In fact, I''d be honoured to be your adoptive brother/cousin/uncle/father.

Dang, we need a bow smilie!

YAY! I hoped you might welcome a coati cub! Thanks uncle-dad-cos-bro! You''re not Korean, Dutch, or Scottish are you?

 

[Harriet]

Count me in! You do know that Coati aka Stoner is trouble, right?

 

[oldmancoyote]

Coati: Nope. Italian by birth, lived half my life in the UK (and France, and Spain, and the US). For some strange reason I have a somewhat Scottish accent when speaking English, though. And I am a great admirer of Dutch/Flemish painting...

Harriet: Yep. And you mean to say you aren't?

 

[Harriet]

I''m the good one.

I just saw the den.

 

[oldmancoyote]

Not enough Mauboussin there. I missed out on this one... but the bank manager would not give me a mortgage on it. Silly man.

 

[Harriet]

Bella!

 

[LtlFirecracker]

uh....WOW!
