The Gem Trader just put up a fabulous purple Jeffrey Mine vesuvianite.

That, the bright green from the same place, and the remarkable brilliant yellow from Kenya are great things, but there's just not much of it on the market.

It's a common mineral, but really unusual in flawless clear crystals of any size.

Gotta love those Canadian vesuvianites. Chrome green and topaz-like magenta/purple from the same mine!

I've seen flats and flats of Jeffrey Mine vesuvianite, even collected some back in '87.

A purple that big and fine is exquisitely rare. A ten point stone, I can see that being a possibility, but that thing, sheesh.

That it's even on the market is really surprising; normally material of that quality goes into black hole collections or museums.

I got two small ones ( vivid purple 0,14ct and 0,19ct light purple) from GSK ( I miss him ) last year.

The only time I was able to purchase one. It was on top of my wish list and fortunately Mark ( GSK ) offered these two litte gems to me.

The Gem Trader item looks fantastic!

No.

It is only a very very rare gem material.

This mine is (was) full of curiosities like purple and chrome vesuvianite, Grossular colorless or colorless with a green dot of Tsavorite, Tsavorite ( got some cut ones from GSK too ) and awesome pink Grossular ( never seen a cut one ) and even demantoid. And sometimes large enough for cutting.

Pink grossular is called "rosolite" and is coloured by manganese. It's extremely rare.

Correct me if I'm wrong, but aren't the green grossulars from Canada actually colored by chromium rather than vanadium as with tsavorite? Is there any particular difference in the color?

Difficult to say. Maybe I will give my stones ( 15 items ) to a scientist from Italy who works about garnet ( demantoid ) but I have to be sure they are from Canada - and I am not sure!

They looks identical to african Tsavorite - some are a bit lighter in color but they are to large and clean for canadian Tsavos imo.

But would you expect a 0,81 clean mangano Vesuvianite??

Some show red flourescence ( LW ) but there are Tsavos from Kuranze ( Tanzania) with red fluor. too - I have two of them.

Unfortunately GSK could not give me his exact source for these gems. He got some rare gems from Alpine Gems - a canadian gem dealer part of Coast to Coast. He offers canadian Tsavorite but they look different.

So at the moment they are in my collection as canadian Tsavorite with a (?) ...

But I try to get cut stones and specimen to compare them...

Absolutely not. He knows his stuff.
