funny inclusion

[pyramid]

Saw this on a friends diamond through the loupe (very shallow inclusion but I thought it was weird).

There was a crystal and tiny cavity just at the surface. Well to the side of the cavity was a hairline fracture which followed exactly a surface grain line making the grain line look like it had uneven edges.

Would this mean the fracture was taking the path of least resistance by following the grain line?

Hi Pyramid
I reckon you are spot on. The crystal inclusions are formed under high pressure and sometimes the pressure will “blow out” and will take the path of lowest resistance. It is also not uncommon for gas to be trapped around a crystal.
