I have been long fascinated by American Native jewelry.  This 1&1/2 inch tall American turquoise nugget was slightly polished and set in soldered sterling silver prongs and bail.  Turquoise, orange spiny oyster from Baja Mexico and purple shell from the Philippines completes the 20 inch sterling silver toggle clasp necklace.  This necklace took me years to make but I like the new finished look!!!
