Most Popular Bi-color Gemstones
Below, we will discuss the main types of gemstones with two colors, their properties, and symbolism.
Tourmaline – the most popular bi-color gemstone
Tourmaline is often considered the most popular gemstone that can have two or even more colors. Particularly well-known is the Watermelon Tourmaline, whose colors resemble a watermelon: green shades on the outside and pink on the inside. Such gemstones symbolize love and energy.
Ametrine – a combination of two quartz colors
Ametrine is a natural gemstone that combines the purple of amethyst and the yellow of citrine. Citrine is a yellow form of quartz, valued for its aesthetic appearance and symbolic meaning. This transparent multi-colored gemstone is often considered special due to its natural contrast. Jewelry with ametrine looks exceptional because every stone is unique.
Sapphire – not just blue
Although sapphire usually symbolizes the color blue, bi-color sapphires can also be two-toned. They can feature combinations of yellow and blue, green and orange, or even purple. Such a sapphire is extremely rare, so gemstone rings made of sapphire become very valuable.
Topaz – a play of subtle colors
Topaz can be a transparent gemstone that sometimes features a two-color effect. It is most often yellowish-pink or blue with a greenish tint. Topaz jewelry provides sophistication, which is why this stone is often chosen for earrings and pendants.
Fluorite – a kaleidoscope of colors
Fluorite is one of the most colorful gemstones, as several colors often blend within it. Bi-color fluorite can be purple with green or blue with yellow. Due to its colors, it is especially favored by collectors who seek not only beauty but also energetic properties.
Kunzite – a gemstone of soft tones
Kunzite features subtle pink, purple, and even greenish shades. Although it is not as popular as sapphire or diamond, jewelry with kunzite catches the eye with its soft beauty. This gemstone is often associated with love and spiritual peace.
Tanzanite – a multicolored gemstone
Tanzanite is special because of pleochroism – a phenomenon where the stone changes color depending on the viewing angle. Depending on the angle, it can look blue, purple, or even greenish. Sometimes bi-color tanzanites are also found, which are highly valued. Tanzanite rings are often chosen as jewelry for special occasions.
Diamond – unexpected color combinations
Although diamonds are usually transparent, colored variants also exist. Some diamonds can be “chameleon” – chameleon diamonds are diamonds that can change color depending on lighting or temperature, for example, from green to brown. Such gemstones are very rare and highly valued by collectors for their uniqueness.
Quartz – a versatile stone

Ametrine is a great example, but other quartz variants also sometimes show color transitions. Quartz jewelry is popular because this stone is easily combined with others.
