This listing is for one 22mm x 27mm triangular blue dumorterite cabochon. This stone is a vibrant blue with dark blue spots. The stone is cut 5mm thick and is polished on both the front and back to a high shine. I do all my own cutting in my personal shop. I closely inspect every cab I cut and make sure that there are no visible scratches. I do custom cutting and if you are looking for something that is listed feel free to ask me. I have a large supply of cutting materials and lots of stones that are not listed. Thanks for looking.
