AI Appraisal Estimate

This is a hand-knotted, single-strand necklace featuring graduated, spherical Tiger's Eye gemstone beads. The beads display a classic golden to chocolate brown chatoyancy, a silky luster that shifts with light due to the fibrous structure of the stone. The design features a significant taper in size, with the largest beads positioned at the center front and smaller beads near the clasp. The necklace is professionally constructed with visible white knots between each bead, a quality indicator that prevents the stone surfaces from rubbing together and ensures the beads remain secure if the cord breaks. It is equipped with a gold-toned, cylindrical barrel screw clasp, which is characteristic of vintage jewelry from the mid-20th century, likely between 1950 and 1970. The condition appears very good, with the stones retaining a high polish and no visible fractures or significant chips. The white thread is clean, suggesting it has not been heavily worn or has been recently restrung. The varying widths of the chatoyant bands across the beads highlight the natural origin of the semi-precious material.

I have completed a visual examination of the Graduated Tiger's Eye Bead Necklace. The piece features high-quality, chatoyant Tiger's Eye beads with a desirable golden-brown lustre. The hand-knotted construction and vintage barrel screw clasp indicate mid-20th-century craftsmanship. The condition is excellent, showing no significant surface abrasions or cord fraying. Market demand for semi-precious vintage gemstone necklaces remains steady, though Tiger's Eye is a relatively abundant quartz-based mineral, which keeps the price point accessible compared to precious stones. This specific item gains value from its graduated design and professional stringing. However, a digital image inspection has limitations; I cannot definitively confirm if the beads are natural or heat-enhanced to deepen the color, nor can I verify if the clasp is solid gold or gold-plated without an acid test or hallmark inspection. To finalize a formal authentication, an in-person assessment would be required to check for micro-fractures under 10x magnification and to weigh the piece to assess the density of the mineral. For insurance purposes, provenance or original retail documentation would further support the valuation at the higher end of the provided range.
