Boulder Opal and Gemstone Beaded Necklace

Vintage beaded necklace with a large SOLID Australian boulder opal pendant. 

The beads are citrine, peridot, garnet, sterling silver, and tiger's eye felspar. 

 The pendant is gorgeous! The opal has good natural blue color and small pinfires of violet in the sun. Host rock is a warm banded brown. Just stunning! 

Pendant measures 34mm by 30mm and is 7mm thick. I don't see or feel any edge chips. 

Necklace is 18 1/2" long. Toggle clasp is sterling and a bit tarnished. 

No hallmarks. Weight: 38 grams.
