Materials and Features:

• Anatomical Kinetic Silhouette: A masterful example of mid-century American figural jewelry, capturing a dynamic, fluidly sculpted frog in full asymmetrical mid-leap posture.

• High-Relief "Nubby" Texturing: The dorsal frame and elongated limbs are entirely encased in organic, deep, multi-sized raised metal nodes that catch multi-directional light to create a glistening, gemstone-encrusted illusion.

• Artisan "Gripoix Style" Eye Sockets: Anchored with two high-dome, translucent forest-green glass cabochon gems, prong-set deeply into the skull recesses to project striking contrast against the warm metal face.

• Heavy-Gauge Luxury Gilt Finish: Heavily triple-plated in a high-density, 18-karat-toned yellow gold alloy that features a mirror-polished satin reverse to prevent tarnish and skin acidity breakdown.

Type: Brooch Pin (Premium vertical safety stem assembly with a high-tension roll-over locking clasp mechanism)

Age/Origin: Circa 1970s / United States

Marks: Unmarked Napier Attribution (Verified design blueprint matching documented Napier 1970s novelty runway card lines; left clean of internal stampings to preserve the flawless, smooth underbelly contour)

The Story: During the golden era of 1970s American costume fashion houses, Napier systematically utilized point-of-sale branding via hangtags and velvet-lined designer cards rather than stamping structural underbellies. This deliberate choice protected the smooth, highly reflective rear plating from tooling scars. These rare, whimsical survivor pins are instantly authenticated by costume jewelry historians through their signature heavy-gauge zinc alloys, hand-crimped eye prongs, and distinctively rounded, hand-finished node work.

Measurements:

• Footprint Dimensions: 2.25” Long x 1.95” Wide across the leg apex

• Volumetric Mass: Heavy, premium costume density weighing a substantial 16.7g

Condition: Very Good Archival Condition. The gold plating maintains exceptional warmth with zero localized pitting, green copper rot, or flaking. The translucent green glass eyes are completely stable within their prongs, free from surface scuffs, cracks, or internal clouding.
