Lapis Lazuli beaded necklace

This piece is a long, continuous strand necklace featuring numerous small, graduated disc or rondelle-shaped beads crafted from deep blue lapis lazuli. The physical characteristics include rich royal blue coloration with subtle natural variations, including minor lighter inclusions and faint pyrite flecking typical of the mineral, though material composition remains unverified without physical testing. The beads are smoothly polished yet retain a slightly organic, hand-shaped contour rather than strict uniformity, suggesting traditional lapis crafting techniques. The strand is finished with a simple, silver-toned metal hook-and-eye clasp mechanism attached near the terminal ends. There are no visible maker's marks, hallmarks, or signatures present on the clasp or beads. The overall visual evidence indicates moderate surface wear consistent with age, but no major structural damage or missing sections are immediately apparent from the image. The styling points toward a mid-to-late 20th-century decorative jewelry piece, though exact dating cannot be established from visual observation alone.

Based on what I can see in the photograph, this long, continuous strand necklace features graduated disc-shaped beads displaying the deep royal blue coloration and subtle pyrite flecking visually consistent with lapis lazuli. The beads have a smooth polish with organic contours, and the piece is completed with a simple silver-toned metal clasp. However, I cannot verify the material composition, exact mineral quality, or the silver content of the clasp from a photo alone; physical testing would be required to confirm these elements. There are no visible maker's marks or hallmarks to provide a specific attribution, so the evaluation assumes a mid-to-late 20th-century decorative jewelry piece of this general type. The basis for the value estimate considers moderate surface wear typical of age and the steady decorative market demand for gemstone bead necklaces. If the material is determined to be imitation glass, dyed synthetic stone, or resin rather than natural lapis lazuli, the value would decrease significantly to a nominal reproduction range of $25-50. To establish a more precise evaluation and confirm the stone and metal composition, an in-person examination by a qualified gemologist or jeweler is necessary.
