Edwardian 2.95ct Burma Oval Spinel Platinum+18KY Gold Ring (Antique 1905)

Edwardian 2.95ct Burma Oval Spinel Platinum+18KY Gold Ring (Antique 1905) 1.57ct Old Euro Dia Size GIA

A specific year estimate for this piece is 1905 (with a narrow window of 1903 to 1908).

The physical markers and fabrication techniques that define this date range include:

1. Platinum-on-Gold Lamination

Before the widespread adoption of the oxy-acetylene torch around 1903–1905, jewelers could not reach the high melting point required to cast or weld solid platinum reliably. To achieve the popular white-metal aesthetic without risking brittle welds, bench jewelers fused thin sheets of platinum onto 18K yellow gold bases. The platinum top makes the side diamonds appear seamless and bright, while the yellow gold shank provides structural stability. By 1912–1915, solid platinum alloys dominated, placing this hybrid construction squarely in the early 1900s transition.

2. Transitional Shoulder Aesthetics

The shoulders feature heavy, hand-chased scrollwork with deep dimensional carving. This volumetric, sculptural style is a hallmark of late Victorian design (1890s). However, integrating these heavy gold scrolls with delicate platinum-faced diamond tops marks the exact aesthetic bridge between late Victorian substance and early Edwardian lace-like elegance.

3. Diamond Cut & Setting Style

The side stones are textbook Old European cuts with high crowns, small tables, deep pavilions, and visible open culets. They are set into buttercup/crown style prongs crafted in white metal, designed to maximize light entering from the side while maintaining a low-to-medium profile relative to the shoulders.

4. Center Setting Alteration

The yellow gold center crown basket holding the 2.95ct red spinel was adapted or rebuilt to accommodate the dimensions and depth of the oval stone. The color contrast between the yellow gold center head and the platinum-faced side diamond crowns highlights where the modification took place, preserving the original side shoulders and shank intact.
