Hello,

What do you think about this gemstone ?

I think that this is a natural heated leadglass filled ruby.

I need your opinion about this and other gemstones.

Thank you a lot for the answers.

Hard to tell from those photos, but there are features that look like air bubbles to me.

Any "blue flash" effect when you look at it in person?

Like this:

Hello,
Sorry for the low quality of the photos.

In the photo it's quite invisible... but there is a fracture with blue flash inside.

Perhaps it's possible to see something in this photo....

It's quite impossible to see the blue flash in the photos upon.

Perhaps you can see it in this other photo... but I could not capture it well in the photos.

Air bubbles and blue flashes in fractures are typical of glass filled rubies. It doesn't really matter if you can capture it in a photo. If you see it in person, then that's probably what you've got.

the Doughnut like gas bubble & flash effect does indicate the lead glass.

Thank you for the promt answer !

I have some other questions about inclusions in gemstones.

I found these inclusion in a Padparadscha Sapphire.
I think that they are crystals with tension halos for heating treatment.

Can you confirm my idea ?

I do agree strongly with Ros, that stone is most likely not only heated, it is also filled with glass.
