Vintage shops Southwestern Multi-Strand Bone Necklace

Product Name: Vintage shops Southwestern Multi-Strand Bone Necklace
From my personal collection. What a gorgeous piece! I purchased this in this little antique store, in CA, with tons of Native artifacts, several years ago. I am sadly not sure if this is Native made, as their are no markings, but it is truly amazing. I am spring cleaning, and realize I need to let go of things I don't wear any longer. I may punch myself for selling this, lol, but it deserves to be worn and loved more!!! Missing one strand. Please refer to the pics for condition. I am no expert, but have been designing jewelry for over a decade, and I believe these are bone beads, as they have shops dents in some.
