Description

A chunk of clear summer sky, frozen in crystal.

Cut into a grand oval brilliant, this 15 carat sapphire fires off bright cornflower-blue flashes with every tilt. Sourced from Sri Lanka’s legendary gem gravels, it is 100 % natural—no heat, no chemicals, nothing but Earth’s handiwork. Stones this big, clean and untreated are true trophy gems.

Why it stands out
• Massive 15 ct weight and eye-clean clarity—made to headline a luxury design.
• Oval brilliant cut floods the stone with life and sparkle.
• Cornflower-blue shade prized by high-end collectors.
• Sapphire hardness (Mohs 9) means daily-wear durability.
• Independent lab report available—confirms no heat and Ceylon origin.
