Wow! Cool! I found it in the Liddicoat book. It says "Axinite, a hydrous calcium aluminum borosilicate, is sometimes faceted for collectors."
It described it as being confused with chrysoberyl, hessonite garnet, topaz or tourmaline and described the reddish brown color. Sounded like a good possibility!

This was educational as usual! Thank you Bill!

Well, people, thanks for an entertaining quiz. Rom is right, of course, you can hardly ever (for sure, that is) tell the identity of a stone just by looking.

At one point, someone guessed Axinite for the Hauyne. Anyway, great fun. Thanks!!

Yeah, Wolf, there are some definite similarities between the pictures I have of Kornerupine and Axinite.

Most kornerupine cut as gems is blue or green. I really like the wonderful cat's-eyes but your stone reminded me of a few brown-orange faceted kornerupines I've seen over the years.

Fun quiz but not all that easy IMO. But I'll be studying for next time!

Just finished mowing the lawn.

CONGRATULATIONS CARRIE!!!!! =D>


That's what I get for trusting my B chart :cry: It says that Axinite doesn't come in orange. Didn't think of the red/brown combo as it's pretty orange on my monitor. I guessed Axinite for stone #7, even though it (supposedly, according to my B chart) rarely comes in blue. :P

Well Snizzy, probably every single person viewed the stone in a slightly different color. On my monitor it looks reddish brown, which is listed in GT Pro as an Axinite color.

I have just started exploring the GTP program and it is a great resource! I especially like the gemology review where you can quiz yourself on various gem topics. I have taken many courses and absorbed a lot of information over the last year and a half. Taking some quizes is a great way to refresh my memory and confirm that the info is still stuck in my head. The program has loads of gem data and features. Really fun!

Very grateful!-Carrie

You know what my favorite feature is:
Open the Gemstone Database.
Click on refractive index header. All, RI's are then listed low to high. The same with SG, and all the other categories. That is extremely useful for IDs.
Oh and I also like the fact that everytime you open the product you have a different gem or mineral screen saver.

Hi Barbra,

Two points. Not sure if you've run across this but if you click on the RI header twice it will reverse itself from high to low (the others do this as well).

And since you are using these columns for gem ident, I have to ask if you've used the Gemstone Separator? That's MY favorite part of the program. I only wish I did gem ident on a daily basis (instead of like, never).

Yes, I have used the seperator on 2 occasions. One it was a complete success; the second was on brimsjewerly's famous mystery green garnet.
I don't know if you're been following the saga:

Transparent green garnet with the specs of a hydrogrossular.
Hydrogrossular garnets aren't transparent.
The Seperator gave me a number of things to check, with suggestions for alternative possibilities.
After running the stone thru all its paces, it remains a mystery. :?
It's been sent to the GIA to sort out now.
We are awaiting the results.

Fascinating. I hadn't heard about this green garnet. Sounds like I may have to make some adjustments when the report comes back. One thing is for sure: the Separator isn't fool-proof. I have to keep making additions and adjustments all the time. It's not perfect but it works well most of the time. Where can I find out more about the brimsjewelry garnet? Thanks.
