Dear sh;

Please repost better pictures; if you look at your shots, they all have the fabric background in PERFECT focus, which is why we can't see the specimen clearly. If you have your camera on automatic focus, the focusing sensor tends to use the largest object as the focus point, ESPECIALLY when dealing with small objects. Also, try not to take the shot, with the light going through the piece; that "blinds" us from seeing the external features, which tend to be more important than the specimen's clarity.

From what I do see, in your 3rd shot, there are 3 directions for the growth lines, showing; this would mean topaz is out. Also, 2 of the growth lines meetings seem to be at the wrong angles, pointing to it being something else. In none of the 3 pictures, do I see any sign of a cleavage, which is another negative sign for topaz. The fact that you did a hardness test, helped; however, there are too many other minerals, in pegmatites/granites, that can have a hardness greater than 7.

Better pictures will help.

Your friend, Steve

It would also be helpful to provide a locality.

A simple SG test would also help a lot, since one doesn't have much else to work with here.

thanks to Mr Steven Garza, Mr Harald Schillhammer and Mr Reinhardt van Vuuren for replies......i was 'nt around for some time.

sir. this mineral could be either from Pakistan or Afghanistan, it is inert to both LW & SW Lights,

thanks

Dear Abdul;

Not sure what it could be, BUT, I can tell you that's not topaz. On the plus side, with a hardness of 7+, it's GOT to be something rare & very unusual. The only one I could come up with was chrysoberyl.

Well, I have a short list of five guesses. But off those photos and scant other information, I'm keeping my mouth shut :-)

I'll bet a six-pack that it not chrysoberyl. Make that a half dozen of Pol Roger :)-D

Sorry Abdul. We Nasrani like our grape juice fermented :-)

Dear Owen & Abdul;

I have to agree; that can't be chrysoberyl - striations (even for bizarrely twinned xls) are wrong.

Hello AbdulB Sh,

I think your specimen looks like a piece of aquamarine (beryl), going by colour and hardness. It looks like it has formed within other minerals (eg. Microcline feldspar) so it does not show any proper crystal faces, which would explain it's strange shape.
