Hi everybpdy,
I have recently bought a nice pendant with a 7x5 mm chrome diopside from Russia.
The gem is included, some inclusions can be disclosed also with the unaided eye. I observed these inclusions under microscope, but it was hard to focus the inclusions... they appeared to me almost doubled. I thought that it might be due to the fact that diopside presents birifrangence (?).
However, I found some tubular structures that I was not able to ID

Here with oblique lighting

With greater magnification

MIght they be "growth tubes"?
What do you think about these inclusions?
Thank you all
Grazie
:D

or may be somthing else but these inclusions are not comon for chrome diopside and it does not double the image if magnification is not so strong. and the color of your stone does not look like chrome diopside

Thanks for your kind reply, energyos :D
The gem has been sold and certified to me as "chrome diopside"...
I read that "fibrous inclusions" might be found in diopside
http://gemologyproject.com/wiki/index.p ... e_Diopside
But I don't know whether these "tubular" inclusions might be classified also as "fibrous".

Ciao!

Diopside often has fibrous inclusions of some sort or other, hence cat's-eye/star diopside. I've never seen a chrome star diopside, though.

I don't think your photos have the resolution that enables identification of anything.
Sorry.

suggestion: if you stick a Linear Polarizing filter on the objective of your microscope you could get rid of the doubling.....at least.
