Dear friends,
I have recently bought this dark pink tourmaline...
Looking at the the stone, I noticed a white spot under one of the facets of the crown.
At first, I thought it could be a scratch due to the faceting process, but when I observed the stone under magnification I found this iridescent inclusion...
Here some images

Might you be so kind to give me a suggestion for identifying this inclusion?
Thank you in advance!
Ciao

Looks like an air filled internal crack causing an interference phenomenon.
