Vintage Czech opaline glass necklace featuring alternating faceted translucent blue-white beads and ornate antiqued brass filigree caps. Hand-wired construction with openwork metal bead accents adds delicate, old-world charm. The glowing opaline finish shifts from milky white to soft blue under light, giving it a luminous, ethereal look. Likely mid-century Czech craftsmanship, approximately 18” long, in excellent vintage condition.
