Assorted faceted clear beads with iridescent finish

A collection of loose, faceted beads held in a person's palm. The beads appear to be made of glass or synthetic crystal, manifesting a high degree of transparency and various geometric cuts, including bicones, rounds, and rondelles. Many of the beads exhibit an iridescent or 'Aurora Borealis' (AB) style coating, which produces a spectrum of colors—predominantly yellows, blues, and purples—when they catch the light. The beads vary in size, approximately ranging from 4mm to 12mm. While the owner refers to these as 'stone,' their visual properties, including the specific type of light refraction and the presence of molded-looking facets and drill holes, are more stylistically consistent with pressed glass crystals or acrylic craft beads. There are no visible maker's marks, brand labels, or signatures on these loose objects. Most appear to be in good condition, though a few small fragments or chips may be present among the smaller pieces. These are consistent with materials used in mid-20th-century to contemporary costume jewelry making. Without physical testing for hardness or specific gravity, the exact material composition remains unverified.

I have examined the digital image of the assorted faceted beads. Based on my visual analysis, these items appear to be mass-produced glass or acrylic beads with an iridescent 'Aurora Borealis' finish. While the owner identifies these as 'stone,' the visible surface luster, mold marks, and uniform drill holes are more characteristic of manufactured costume jewelry components. I cannot verify the material composition or specific gravity from a photograph; a physical hardness test would be required to rule out lead crystal or synthetic glass. The collection shows varying sizes (approx. 4mm to 12mm) and shapes including bicones and rounds, which are typical of mid-20th-century to contemporary jewelry findings. The estimated value reflects a bulk lot for crafting purposes rather than a collection of precious or semi-precious gemstones. In the current secondary market, such lots are valued based on weight and perceived quality for repurposing. Because these lack a verified maker's mark (such as Swarovski) or provenance, they are appraised as generic decorative components. If these were confirmed to be vintage Swarovski lead crystals, the value might increase towards the higher end of the range ($35-$50). However, if they are determined to be modern acrylic/plastic reproductions, the market value would likely fall below $10. To refine this estimate, an in-person inspection of the facets for crispness and a 'cold-to-the-touch' test for glass vs. plastic would be necessary. The current estimate assumes they are glass-based costume elements in good condition.
