Bi-colour sapphires are stones that contain two colours as a result of colour zoning. Sometimes referred to as parti sapphires, the two colours are obvious to the naked eye and do not change under different lighting conditions. The range can sway from very dramatic colour zoning, displaying two very different colours in the stone, to very slight colour zoning that shows two very similar, but still different colours in one stone.
Some colours are more rare then others, the most common and least pricey is the yellow and green. All other colour combinations arecombination is rarer and thus more valuable.
These gemstones are popular choices for custom jewelry designs, allowing jewelers to create pieces that emphasize their unique features. Rings, earrings, pendants, and bracelets featuring bi-colour sapphires often highlight the transitions between colours, creating a dynamic and eye-catching look.
