Beautiful handmade stone and shell inlayed butterfly necklace

Gorgeous hand crafted turquoise and spiny oyster shell inlayed beaded butterfly necklace. Polished stone and coral beaded 22” necklace with 2x3.5” silver butterfly attached pendant. The craftsmanship is beautiful. The butterfly isn’t stamped sterling, but may be. Looks like Larimar stone, Dragon Vein orange agate beads, spiny oyster shell wings (?), coral and maybe turquoise. Abalone shell on wings too. Excellent condition.
