Vintage Western Southwestern handmade statement pendant w Paua Abalone shell

One of a kind vintage handmade silver pendant. Western / Southwestern. Inlaid with pieces of natural Abalone Paua shell and what looks like black onyx stone (but could be some other type of stone). In excellent condition. 2.75" long (with bail). Intricate bail is made of silver tone metal, but not stamped (or I can't find it). Quite beautiful.
