This cabochon weighs 10.9 carats and measures 2cmX 1.5cm. It is priced at $40 a carat or $436. It is not treated and backed. I have assigned a TG of 86 or VHG. I purchased this from Dayton Simmons who purchased from the owner of a discovered stash hidden in the floor boards of a saloon across from Dowell Ward’s warehouse..
