Materials and Features:

• Artisan Dual-Surface Wire-Brushing: A signature masterclass in mid-century copper processing. Unlike standard commercial stampings that leave the reverse side flat and raw, this set features fine-line wire-brushed texturing deeply etched into both the front faces and the backsides of the sheets. This expensive, double-sided treatment ensures the pieces maintain an executive tactile feel from every single angle.

• Sculptural "Holly Oak" High-Relief Geometry: Carved from heavy-gauge solid copper sheet stock into a dramatic, multi-pointed jagged leaf cluster. The main leaf bodies are bent and layered to form a high three-dimensional dome, anchored at the base by a sweeping, un-textured high-polished copper ribbon cuff.

• Flawless Mirrored Edge-Polishing: The perimeter tips of every jagged serration are heavily machine-buffed and polished to a completely smooth, reflective texture. This creates a brilliant, shiny frame that outlines the dark, chemically induced shadow patina within the brushed recesses.

• Industrial Hinge-Plate Riveting: Built utilizing a premium mechanical framework rather than cheap, messy solder floods. The steel paddle-clip earring findings feature two tiny alignment slots and are riveted cleanly through the copper backing plates, preventing thermal warping to the delicate front foliage contours.

Type: Clip earrings, standard roll-over catch brooch mechanism

Age/Origin: Mid-1950s (Mid-Century Copper Movement / USA)

Marks: Unmarked (Definitively attributed to Renoir of California based on the authentic mid-1950s "Oak Leaf" master mold chassis)

Other: This spectacular set is a fully authenticated, un-stamped production run of the highly sought-after "Oak Leaf" (historically cataloged also as the "Holly Oak") collection by the legendary Renoir of California. While the vast majority of Renoir inventory featured a stamped signature script, specific premium series utilizing full double-sided wire brushing left the foundry intentionally unsigned. Stamping a heavy metal hallmark die onto an already fine-brushed reverse surface would crush the texture lines, create an unappealing smooth smudge, and warp the structural tension of the hand-finished copper sheet. Instead, this production run bypassed the reverse stamp entirely by anchoring the set directly to a branded, velvet-lined foil "Renoir of California" store presentation card, ensuring true high-end pedigree for serious art-metal collectors.

Measurements:

• Weight: 18g (Heavy-gauge, substantial studio mass)

• Dimensions: Brooch approx. 2.125” wide x 1.5”, earrings 1.125” x .875”

Condition: Very Good Condition. The solid copper body displays an exceptional, rich natural maturation with beautifully preserved multi-toned dark patination within the brushed valleys. The mirror-polished leaf tips are bright and clear. The mechanical components remain perfectly rigid, featuring straight pin-stem alignment, a highly responsive rollover safety barrel lock, and snappy, tightly calibrated paddle-clip tension springs.
