If they determine it to be synthetic, then there will be no further testing. If it is indeed a ruby, then they will tell you the treatment and the level of treatment, which helps immensely in knowing how to care for your new ring and how safe it is to repolish the ruby (which needs to be removed from the setting for this work).

Really inexpensive but does not tell you the extent of treatment.

Pricing for a more thorough verification.

the aglgemlab gembrief isnt useable, it limits up to 3 cts.
I will use the GIA lab and send it out next week. These places are busy it seems, 30 day turn around time.
