Start things off by saying the inclusions are in a 1.25 ct Cobalt spinel- I think from Vietnam but could be from anywhere (though probably Vietnam).
It's a weird one... Yellow squigglys, like angel-hair pasta. Color is kinda like banana peel yellow, and opaque.
Not really noticeable by eye but very clear with 10X.
Any ideas what this could be?
Thanks!
David

No nothing like the mine but I'm really impressed anyway. Thanks for the effort. At first I thought your pics were of two different inclusions, and then wow, it's just higher magnification
I know that a written description is very difficult to identify so I'll try to draw something up in PS soon.
The inclusion definitely has the look of opaque yellow twine/rope/fibers.
Hey! if anyone in U.S. would be willing to photograph it for me- I'll send them the stone? (but I want it back, please)
The inclusion is described but not identified. BUT, when you find this thype you hqve a confirmation thet the stone is not synthetic, In addition your stone has octahedrals which are common to spinels.
compare to yours, David:

Wow that babelfish translation was much better than I would have expected!
Thanks for that link.
The pictures on the other hand are exactly as GOOD as I expected.
The list membership will pardon me if I feel a little proud of John and Tim's beautiful recent pix, since I had a little to do with them getting those scopes.
John I see you are starting to get it really zeroed in.
John, thanks for all the time you spent on my stone and all the other pics! I may post another one with the negative crystal... yup looks just like a negative spinel, how odd.
Amazing that you also have a cobaltiferous spinel with the same type and color inclusions wonder if our's are cousins? Do you know where yours came from?

Yup, Gene: you sold me! No buyer's remorse here. Did you see the pics of the system in gem equipment? You can see what I mean when I say "mint".
I'm trying to shorten the learning curve; bit learning the new techniques is fun. Thanks.
YIKES DAVID! That pic was of the inclusion in YOUR stone. However there are some aspects in the first pic posted above that are similat to the fibrous inclusions in yours. That is from a mauve stone.
Ahhh, I see got me confused when you posted the last picture that said 'compare to mine'... thought you had one too! (even though when you sent it last night I thought it was a picture of mine- see? )
Now that's an awesome picture- I'm definitely gonna save it.
Are you able to tell how deep it is from the pavilion facet? I'm trying to gauge if I can reasonably remove it by recutting.
Thanks again John, hey do you have a cobalt spinel? thought I read it in a thread here.

It's deep enough that you would loose a lot of weight. It is just barely visible in the pavilion under bright light. I cannot see it face up. and remember, it's proof that you have a natural stone.
I do have a nice one. I'll see if I can find a link to it.
In that case, do you have an idea how deep it is? so I know how much material I can remove before reaching the inclusion... seems I'm kinda stuck either way

Yes please post a link
I would never consider cutting that inclusion out. I would guess it's .2 to .3 mm in, but that is a 1.25 stone. YOU are the cutter.
