TL, I love that amethyst. But I love all of your gems!
I would love to get a 4 peaks, JXR and a Zamibian and compare them!
I am also trying a 4 peaks from Colorado Gem and Mineral Co...

He said that though the darker material is somehow the standard, it basically turns black in dimmer lighting and also has that tendency when set. He actually steered me away from one of his more expensive ovals because he felt it wouldn't set as nicely as the lighter (still medium though), less expensive amethyst. TL's amethyst does a fine job of flashing the array of colors that can make or break an amethyst, IMHO.

Thanks Facegrace. Actually I think dark flat amethyst can go very black in dimmer lighting. My stone does not at all. It's a medium dark tone, and it is very saturated, and in artificial light, it can go very reddish. The above was taken in indirect sunlight. There is a difference between dark toned amethyst that is not saturated and stones that are saturated. I have a "learner" amethyst, that is very dark, and I don't like it at all.
As for the Zambian amethyst above, when I first bought that stone from a gem dealer many many years ago, he had a darker one and that one which he sent me, and I picked the lighter toned one. The other one was way too dark, and I'm glad I passed over it. My eye for color was still not that great, and I always had assumed darker tone meant better saturation, but it does not.
If you look at much of the Imperial Royal Russian amethyst owned by the Czars, that was the original "Siberian" amethyst as the color was first found in the Urals of Russia (hence the name "Siberian"). Their stones are not dark at all. This is a bad photo of Catheine the Great's earrings, and as you can see, not too dark. They were mined in the Urals.

Some more links to royal amethysts can be seen here. Awful photos, but most of these stones probably came from the Urals.

Having seen candid shots of royals wearing these gems, I don't think they look dark at all. While I don't like amethyst that is too light in tone (Brazilian), I don't think dark tone necessarily makes for an attractive stone as well. There needs to be saturation going on there.
The gemtrader had a Zambian for sale recently, and in this photo you can see some red flashes.

Some really fine amethyst can be mistaken for Tanzanite in certain lighting. I know mine can in sunlight since that tends to bring out more of the blue in the stone.

I got some pictures of available JXR from Brad at Gemtrader. Here are my two favorites, a 3.79 round and a 5.36 oval. Any thoughts on these two?
Thanks again!

I bought 300 grams of it and sold it like hotcakes. The color is very consistant and most are fairly clean with some good pickers. Lots of blue and all are well shaped for yield as all good gemgade zambian material is cobbed anbd has been for years. I bought lots of them from him and they were one of my best selling pieces of rough which was surprising for amethyst. They are all similar to TL's stones color. Pretty much the material from JXR is identical to zambian but the zambian will always be more consistant in color from one stone to the next where as JXR will be very random with gemgrade cleans ones that have the flash of a zambian fairly rare. Literally tons and tons come from zambia each year and have been for 30-40 years where as JXR is only a little 1-2 acre site with maybe not even one ton worth of gemgrade material coming out in it's lifetime(20 years+). Still the finest amethyst I have seen out of all the ones I have seen and sold is a piece of rough Rodney has from JXR...the color is the best I have ever seen (amethystguy has seen lots of amethyst hence the name) and not only that it's big100+cts and clean clean clean. If you want blue flash try to snag some zambian as you can't go wrong...the JXR material typically needs to be hand selected to suit your needs since some will have not much blue in them and others will have tons and what one person considers a lot of blue another may not. I know he has some zambian rough left as of 3 weeks ago..no cut stones and he has lots of JXR material in all forms.
Does anyone know from whom Brad at Gemtrader gets his JXR material?
