This teal sapphire shows a beautiful blend of deep blue and rich green, giving it that highly sought-after blue green sapphire look. The subtle colour zoning creates a natural parti sapphire or bi colour sapphire effect, making the stone shift in character as it moves in the light – a style collectors often call a mermaid sapphire or peacock sapphire.
The radiant cut gives this gemstone a sophisticated, geometric appearance, emphasising clarity and colour over sparkle. It is an ideal choice for a clean, architectural engagement ring or a minimalist statement ring. As a loose sapphire, it gives you complete freedom to design a one-of-a-kind piece.

Mermaid, Peacock & Parti Sapphire Colour
Because of its blue-green zoning, this gemstone fits perfectly into the parti sapphire and bi colour sapphire category. The colour mix is often described as mermaid sapphire or peacock sapphire, as it mirrors the shifting hues of tropical seas and peacock feathers. This makes it a fantastic choice if you want something more unique than a classic single-colour blue sapphire.
No two parti sapphires are exactly alike, so this teal blue green sapphire is truly one-of-a-kind.
