This is a handmade beaded necklace featuring earthy brown stone beads accented with purple amethyst rounds and intricately carved figural beads.

Based on the materials, design, and market trends for vintage artisan jewelry, a 30-inch necklace of this style generally holds an estimated market value of $45 to $85.

The breakdown of factors influencing this valuation includes:

• Materials: It features genuine semi-precious gemstones, primarily picture jasper (the brown, landscape-patterned round beads) and amethyst (the purple rounds). It also includes small freshwater pearls and hand-carved focal beads (likely carved bone or cinnabar-style resin). 

• Craftsmanship: The piece is an artisan, hand-knotted or hand-strung design featuring a custom wire-wrapped hook closure. 

• Market Comparisons: On vintage marketplaces like Etsy and eBay, comparable 1990s or estate-era multi-gemstone statement strands of this length frequently list and sell within the $50–$90 range depending on the designer signature or the exact material of the focal carvings
