Vintage platinum diamond spray brooch of elegant three-dimensional design featuring articulated cascading tiers of marquise cut diamonds that create graceful movement when worn. The brooch is composed of multiple diamond sections arranged in a dynamic spray motif, allowing the articulated elements to move gently and enhance the play of light across the diamonds.

The brooch is set with a total of ninety-eight diamonds weighing approximately 10.40 carats combined. The composition includes forty-one marquise cut diamonds forming the articulated cascading tiers, thirty-two straight baguette cut diamonds arranged in curved ribbon motifs, and twenty-five round brilliant cut diamonds clustered in the central design. All diamonds are prong set, allowing maximum light return and emphasizing the contrast between the different diamond shapes.

Crafted in platinum, the brooch has strong dimensional presence rather than a flat profile, giving the jewel exceptional depth and sculptural character. The articulated tiers of marquise diamonds form elegant draped elements that move freely, creating fluidity and brilliance typical of fine mid-twentieth century European jewelry.

The brooch measures approximately 53 mm by 37 mm and weighs 28.69 grams. Total diamond weight is approximately 10.40 carats.

Articulated diamond spray brooches of this scale and craftsmanship are increasingly sought after by collectors for their movement, refined construction, and distinctive mid-century design.
