This teal sapphire beautifully combines deep blue and lush green tones in a single crystal, creating that highly desirable blue green sapphire look. The natural parti zoning gives the gem personality and movement, shifting subtly as it catches the light – exactly what many collectors describe as a modern “mermaid sapphire” or “peacock sapphire”.
The oval cut enhances both colour and brilliance, making this stone an outstanding centrepiece for a custom engagement ring or statement ring. As a loose gemstone, it offers complete freedom of design, whether you prefer a clean solitaire, a diamond halo, or a bold contemporary setting.

Mermaid & Peacock Sapphire Colour

This style of teal sapphire has become highly sought after in the USA, Australia and Europe as an alternative to traditional blue sapphires and emeralds.
The unique colour zoning means no two parti sapphires are exactly alike, making this gemstone a one-of-a-kind choice for someone who loves individuality and modern colour palettes.
