1.57 ct Natural Unheated Parti-Colored Sapphire (GIT Certified) – Cushion Cut, Purple–Blue

A gem painted by nature’s own hand — where blue meets violet in perfect harmony.

Certified by the Gem and Jewelry Institute of Thailand (GIT), this 1.57-carat Parti-Colored Sapphire is an exceptional natural crystal showcasing a vibrant transition of purple and blue hues. The interplay of colors is entirely natural, revealing how trace elements shift during sapphire formation within a single crystal.

This unheated sapphire — confirmed by GIT as showing no indications of heating — preserves its pure internal structure and natural optical character. The modified brilliant-step cushion cut maximizes both brilliance and color zoning, revealing distinct flashes of violet, indigo, and cornflower tones under shifting light.

Perfect for collectors and designers who appreciate gems with distinct personality and geological storytelling.
