This treated any how. Very low Value

yes you are right but there is tonnes of it going into jewellery all over the world, and has been for many years

I had my supplier give me a bag of them heat treated glass filled rubies which is still in my (maybe cut later) drawer. That goes to show the real quality of these gems. Merry Christmas everyone!

I am a noob in relation to all (if not then definately most) on here, but from what I have read all your paying for with a filled stone is basically a rubbish grade stone and the time for the worker to fill them.
My thoughts are, wages being so low in Thailand that bit is basically free.

Buck.
