No two bicolour sapphire engagement rings can ever be alike. The bicolour sapphire — or parti-colour — displays two distinct hues within a single gem: blue and green, yellow and blue, pink and violet, shaped by the unique chemistry of its crystallisation. Every stone is a mineral landscape in its own right, brought to life by the lapidary's cut, and shares the 9/10 hardness common to all sapphires.
Our bicolour sapphires are sourced directly from our partners in Sri Lanka and Madagascar, certified, and then set into a design conceived to reveal their dual tone. A close cousin, the teal sapphire blends those two colours into one; the green sapphire draws out their most singular facet.
