Treatment disclosure, please read
These sapphires are glass filled (also called lead-glass filled or fracture filled). Natural fractures in the stone have been filled with glass to improve transparency and colour. This is a common treatment for affordable sapphire, and it's the reason these large stones are priced far below heated or untreated sapphires. Glass-filled stones need gentle care (see Care below).
Why a cabochon
A smooth, domed cabochon shows colour rather than sparkle. Light pools inside the dome, giving a deep "liquid blue" look, and the natural silk adds a soft glow.
Design ideas
- Statement drop or stud earrings, using one stone each
- A bold cocktail ring or a men's cabochon ring

Care
Care for glass-filled sapphire:

- Avoid ultrasonic and steam cleaners, acids and household chemicals, including lemon juice
- Tell your jeweler the stones are glass filled, since the heat of a jeweler's torch and re-polishing can damage the filling
