Zuni Turquoise Coral Ring Early Juan Effie C Calavaza Heavy Silver Snake Sz 10

Stunning very old Vintage Zuni Ring with bezel set rustic chunks of Turquoise and red Coral. Thick walled saddle Ring attributed to an Early Juan or Effie C Calavaza. Made with Heavy sandcast Silver (tested) Sz 10 on a ring mandrel It’s Most likely from mid century to 1960s as Juan died in 1970, many pieces prior to 70s were unsigned The textured snake is really important here. The best guess I have from research is that its an unsigned, Juan Calavaza attributed piece as Effie’s were most always smooth faced. The Calavaza family has many makers and are known for this signature snake in different numbers and configurations their legacy of craftsmanship is well respected. This is being offered un polished with original patina. It’s got age and charm, inside has an old solder repair most likely there to smooth out the interior from sand casting process, I find no marks but it is pretty blackened It weighs 1.9 oz which is over 53 g? That’s according to Siri lol
