I have a customer who would like for me to make a ring with a 20mm
round blue chalcedony just like one I made for her in black onyx. She
is very particular and wants the size and height of the stone to be
very much like the black onyx. It was just a machine cut 20 mm stone
from Rio Grande. (Yes, she is aware the chalcedony will be much more
Does anyone know where I might find one or is someone interested in
cutting one? So far, all I have found are 16 - 18 mm stones with a
much higher dome.
Thank you for any help!
