What do you think of this alexandrite inclusion?

Not buying or anything, but while looking at alexandrite for a different thread I came across this lot, pics attached below:

I noticed the emerald cut has an iridescent inclusion and it looks to be near the surface. This reminded me of a previous post I made where it was assumed that a tsav with an iridescent inclusion close to the surface was an indication of filling. It's listed as having no treatment, but I'm very curious if there are any thoughts on this.

I'm not saying David is selling a filled alexandrite as untreated, nor am I trying to start anything. I'm just curious about the inclusion and what it could be.

A simple fracture reaching the surface will produce that effect.

Same opinion! Just air in a fracture....

And this is the reason why it is a bargain - the CC is nice! But you would hate the stone ( same with yelloworange iron stains) course it is the first you see.

Maybe filling would be a good idea ...

Thanks for clarifying.

Another in agreement with the above.
