“Ice Age” 1.5ct Oval Egg-shaped Silica Ring | Rhodium-Plated S925 Silver with Blue and White Flame Band GRA Certified

Inspiration Trace: Optical Narrative of Glacial Ablation
The ice-core air bubbles of Quaternary glaciers form a unique blue and white bi-color halo when light is refracted, which becomes the core design logic of this ring. The physical trajectory of light penetrating the air bubbles in the ice is reproduced through the step-cutting process of Silica Carbonate (SiC), resulting in an iridescent gradation from icy blue to silver-white in the main stone under a D65 standard light source, with a 247% increase in intensity of fire per carat compared to traditional gemstones.
