Materials and Features:

• Architectural Floral Spray Geometry: A textbook mid-century Coro layout featuring a tiered asymmetrical spray of brilliant crystal rhinestones clustered against flowing leaf overlays.

• Brilliant Vapor-Deposited Iridescence: Set with 7 premium glass chaton rhinestones featuring a pristine Blue Aurora Borealis vacuum coating that projects high-flash hues of indigo, violet, and gold.

• Dual-Texture Ribbon Leaves: The overlapping sweeping foliage displays a fine brushed linear texture across the rhodium face, creating a soft matte contrast against the high-octane glitter of the stones.

• Corrosion-Resistant Rhodium Shield: Triple-plated in dense, non-magnetic industrial rhodium to deliver a permanent, mirror-bright silver finish that completely resists atmospheric oxidation and skin acidity.

The Story: Unsigned companion pieces were systematically distributed by Coro during the late 1950s, frequently sold on branded presentation cards or as part of multi-piece jewelry sets where only the primary necklace or brooch carried the main stamp. These pristine survivor lots are instantly authenticated by design historians through their specialized prong counts, base metal alloys, and signature leaf texturing.

Measurements:

• Dimensions: 1.25” Long x 1.00” Wide

• Volumetric Mass: Balanced mid-weight costume density

Condition: Excellent Archival Condition. The rhodium plating remains completely continuous with no pin-hole pitting. All 7 Aurora Borealis rhinestones are structurally tight with zero foil degradation or cloudy cell transition.
