Large 27 mm Chased/Engraved Copper Focal Bead w/ Buddhist Symbols

Description

Himalayan large copper focal bead with Buddhist symbols. The ones I recognize are the sanka, a conch shell to announce the glory of his holy name, the pink lotus representing the sun, the padma representing purity and discriminating wisdom, and the shirivasta (patta), which is an series of endless knots standing for long life and eternal love.  There are a few other symbols as well that I do not recognize.  The bead is 2.7 cm in diameter and weighs 0.52 oz.  The bead is mostly copper colored but has some small areas that are more gold in color.
