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.

I leave my garnets for the moment and try to capture beauty of Feldspar

First classic moonstone on Orthose



Then North Mexican Bytownite Feldspar ... Some of them show twining typical of the pliagioclases
