Design & Construction
Platinum filigree mounting features intricate Art Deco geometric patterns with millegrain detailing characteristic of 1930s craftsmanship. Open-back setting maximizes light transmission through the star sapphire, enhancing asterism visibility. The six-ray star phenomenon creates moving light bands across the cabochon surface under direct illumination. Old-cut diamonds are integrated throughout the ornate platinum framework, providing vintage sparkle that complements the sapphire's mystical star effect.
Historical Significance
This AGL-certified unheated Ceylon star sapphire represents exceptional rarity, combining substantial carat weight with natural asterism and provenance from Ceylon, Sri Lanka's legendary gem deposits. The Art Deco mounting preserves 1930s jewelry artistry, making this piece both a gemological treasure and historical artifact.
