Tufa hearts were in the bench when I made a batch of rough,rich textured hearts. The ancient art of Tufa casting produces a texture unmatched by any other casting. Hard carved by me in the volcanic ash of hardened stone and then silver is melted in a crucible and poured into the laborious prepared forms. So the Turquoise came next, hand cut & polished by my turted lapidarist from Moriarty NM. Then I made the shank in adjustable form that fits sizes 5.5 - 8 lots of love in this ring!
