Need info on rare stones

Hi there,

I will soon put some rare stones on my Website. In order to
carry out my project, I’m looking for precise
(crystal system, chemical composition, color, hardness, specific
gravity, refractive index, dispersion and pleochroism) concerning
the following stones : Bytownite, Clinohumite, Ekanite,
Eosphorite and Jeremejevite.

I know that it is not an easy question. So, is there such an
expert out there ?

Thanks

rare stones. This site may help. I did not download the zip
files and check out what they had to offer.
