Mid-Century Vintage Diamond Multi-Row Bangle Bracelet

This is a vintage hinged bangle bracelet featuring approximately 1.50 to 2.00 total carats of round brilliant-cut diamonds. The piece is crafted in white metal, likely 14k or 18k white gold or platinum, given its age and quality, though no hallmarks are visible. The design features an airy, open-work bypass aesthetic with five distinct rows that taper and widen at the center. The central section is accented by eight larger individually prong-set round diamonds arranged in a staggered geometric pattern typical of the late 1940s to early 1950s Mid-Century aesthetic. The outer rows are grain-set with smaller accent diamonds, adding a cohesive sparkle across the entire face of the piece. The construction utilizes a box clasp integrated into the band with a side safety latch for security. Given the 70-year provenance, the style aligns with the 'cocktail' jewelry era where white metal became the standard for showcasing the brightness of diamonds. Condition-wise, the metal shows a soft patina from age-appropriate wear, and all stones appear to be present and intact. The craftsmanship indicates high-quality bench work, particularly in the symmetry of the wirework and the precision of the diamond spacing.

I have conducted a visual examination of this Mid-Century Diamond Bangle, a quintessential example of late 1940s to early 1950s 'Cocktail Era' jewelry. The piece displays high-quality bench work characteristic of the period, featuring a five-row bypass design with 1.50 to 2.00 total carats of round brilliant-cut diamonds. The symmetry of the open-air wirework and the staggered geometric setting of the central eight stones suggest a skilled craftsman. The condition appears consistent with a 70-year provenance; the soft patina is appropriate for vintage white gold or platinum, and the integration of a side safety latch indicates a high-end construction standard meant to protect a significant investment. The market for Mid-Century diamond jewelry remains robust, with collectors specifically seeking the 'airy' aesthetic that preceded the heavier styles of the 1960s. Comparables for multi-row bypass bracelets of this carat weight and period typically hammer between $4,000 and $7,000 at specialized jewelry auctions, depending on diamond clarity (speculated at VS2-SI1 based on luster). However, there are limitations to this digital assessment. Without a physical inspection, I cannot confirm the metal purity via acid or XRF testing, nor can I verify the exact color and clarity grades of the stones. To finalize this appraisal, an in-person examination is required to check for hallmarks inside the clasp and to ensure no stones have been replaced with synthetics. I recommend a professional cleaning and a laboratory report from the GIA to maximize value and confirm the absence of modern enhancements.
