Description

The sapphire shows a refined blue that reads vivid and sophisticated without looking overly dark. The “cornflower” character is especially appreciated for its balanced beauty—fresh, lively, and naturally luxurious in both daylight and indoor lighting.

Cushion cut — soft shape, premium style

The cushion shape blends gentle rounded corners with a structured outline, giving the stone a romantic yet modern feel. It’s a favorite for:

  • classic solitaires

  • halo rings

  • vintage-inspired settings

  • elegant pendants

A versatile center stone

Cushion sapphires look exceptional in white gold or platinum for a crisp, high-end contrast, and equally beautiful in yellow gold for a warm, traditional look. At 1.21 ct, this stone has strong presence while remaining perfectly suited for everyday fine jewelry.

A timeless Sri Lankan cushion sapphire in a refined cornflower-blue tone—an elegant choice for a signature jewelry piece.
