Geologic Stones...
Ring in 925/1000 silver (47.6 grams), Opal (11.55 carats) and diamond (0.30 carat)
Before becoming a jewel, I sculpted it entirely in wax using as only tools a saw and a crack cutter with each time a different cutting angle, I made different layers in order to melt it in silver.
I then applied the patina so that my work has even more relief.
