Necklace
Turquoise, Sterling Silver, Spiny Oyster
20 inches
This 1+3/4th inch American turquoise nugget was found at an Arizona Rock Swap Meet in a rusty coffee can.  With slight polishing, I soldered sterling silver prongs and bail and found a strand of American turquoise baroque beads, orange spiny oyster from Mexico and purple shells from the Philippines.
Polish silver with a rouge cloth.  To retard oxidation, store in a ziplock baggie.
