Here we go... Looks like flint-knapped arrowhead, looks like gold dip, looks like brass wire chain. IS two strands of howlite beads, IS adjustable, IS eye catching! Only clasp and extender chain react to magnet. Pendant is very lightweight, so I don't believe it's stone, but I could be mistaken. Gold coating is worn a bit on one of the ridges, likely from rubbing during normal wear, you can turn that side to the back.

Shorter strand approx 13" - 16"

Arrowhead approx 1.75" x 1"
