Vintage Graduated Collet-Set Crystal Tennis Bracelet

This is a vintage-style tennis bracelet featuring a graduated design where the center stones are significantly larger than those near the clasp. The bracelet is composed of approximately 20 round-cut colorless stones, likely paste (lead glass) or high-quality cubic zirconia, though their specific faceting suggests mid-20th-century costume jewelry production. The stones are secured in silver-toned metal collet settings, each held by multiple fine prongs. The metal appears to be a rhodium-plated base metal or sterling silver, showing a bright, reflective finish typical of mid-century fashion jewelry. The construction involves individual articulated links that provide flexibility on the wrist. Notable features include the symmetrical graduation of stone sizes and a traditional fold-over or tongue-and-groove clasp, visible at the top. Condition-wise, the stones appear to retain good brilliance with no visible 'dead' or yellowed spots, although minor surface abrasions consistent with age may be present upon closer inspection. The setting shows no significant tarnish or metal loss. This style is reminiscent of the Art Deco or Retro periods (circa 1940s-1950s), frequently styled as 'diamond imitators' for formal evening wear. The craftsmanship is tidy, with uniform prongs and smooth articulation between the individual stone housings.

Upon physical-visual inspection via the provided imagery, I have assessed this vintage graduated collet-set tennis bracelet. The piece reflects the design language of the late 1940s to early 1950s costume jewelry market, specifically intended to mimic high-end diamond line bracelets. The stones exhibit a high lead content or 'paste' composition, indicated by their crisp faceting and refractive quality, while the silver-toned metal shows the characteristic luster of rhodium plating over a base metal or sterling silver. The articulation remains fluid, and the prongs appear secure, which is vital for this era. Market demand for mid-century costume jewelry remains stable, particularly for 'timeless' designs like graduated tennis bracelets that can be worn with modern attire. Comparables found in specialty vintage boutiques often trade in the $150 range, though exceptional pieces from known makers (like Eisenberg or Trifari) can command more. The value here is driven by its excellent 'eye-clean' condition and the aesthetic appeal of the graduated scaling. Limitations: This appraisal is based solely on digital images. A physical examination is required to check for hallmarks, verify metal content via acid testing, and determine if stones are glass or synthetic spinel/CZ. Evaluation of the clasp mechanism's tension and a loupe inspection for 'flea bites' or internal carbon spots would be necessary for a definitive valuation. Documentation of provenance or an original gift box would further solidify its historical context and potential premium.
