Labrodite tie clip stamped 1818.

Labradorite treats colds, gout, and rheumatism, lowers blood pressure, and aids in digestion. The gemstone creates a shield for auras and protects against the negativity of the world. Labradorite is said to temper the negativity within ourselves as well. when I tell u the Labrodite colors are so pretty. the flashes are amazing for a piece like this. 2.5" wide. this piece is also signed but I can't tell by whom
