Materials and Features:

• Artisan "Jelly Shard" Inclusions: A technical signature of the Parisian Steinberger Studio. These earrings feature perfectly sliced, straight-edged navy blue shards suspended at the fusion horizon of a deep-plane Lucite sandwich. The precision of the hand-laid inclusions confirms a high-labor artisan process where each element was hand-placed before the final clear pour.

• Archival Clear-on-White Lamination: Crafted using the specialized Steinberger "sandwich" technique—a crystal-clear top layer chemically bonded to a solid white base. This industrial fusion locks the navy shards deep within the material DNA, ensuring the graphic geometry is protected from surface wear.

• "Marble-Clank" High-Density Lucite: Confirmed by a 1.07 g/cm³ density ratio, these squares possess the superior molecular tension and optical clarity characteristic of Steinberger’s mid-century industrial pours. This provides a distinct, stone-like resonance and substantial "Executive" weight.

• Stable Pierced Boutique Hardware: Featuring silver-tone posts anchored by wide-disc stabilizers. While most 1960s statement pieces rely on uncomfortable screw-backs, these were pioneered by high-end French boutiques for the avant-garde market. The visible ambering of the archival adhesive confirms their 60-year-old historical provenance.
