Hi folks
I launch my video project to create some video on Inclusion in stone and as i say in another
It is "cheap" gemology
I have begin with some quartz, now i go on the garnet Pyrope/Almandin serie

I hope to find help in order to try to identify some of the inclusion.

I do my pictures in transmited light and polarized light, i am currently working on a very cheap "Dark Field" chamber but for the moment i have still problem of light uniformity.

In the first video, i have Solid inclusion
I know that Apatite is often found in Pyrope .. but can it be other things ?

At 1min you see a well terminated mineral




The second video is a Rutile Network




The 3rd video is a stone with a lot of inclusion in rutile network
I am curious to know if someone know what are "Black inclusion" ... Rutile in other form than Needles ?

I resume my works in Pyrope/Almandine Garnets for my Video Library based on inclusion

2 small video (i want to stay under 1 min each time) of Zircon like inclusions in Garnet. Stress Cross under polariscope. (I have always thought it was Thorium Radioactivity in Zircon) :





Another Rutile Silk in a pear chape :



And a very nice (favorite stone for the moment) ... Apatite certainly with some rutile needles :



If you see something else or if i am wrong, thx for help.
