Bi-color tourmaline is a variety of the tourmaline gemstone that displays two distinct colors within a single crystal. This natural color zoning occurs due to variations in the chemical environment during the crystal’s formation, typically in pegmatite rocks. Here’s a more detailed description:

Bi-Color Tourmaline – Gemstone Description

Appearance:

Bi-color tourmaline features two clearly defined colors that blend or transition within one crystal. Common color combinations include:

• Pink and green (often called “watermelon tourmaline” when the colors are arranged concentrically)

• Blue and green

• Yellow and pink

• Purple and orange

Each gem is unique, with the colors appearing in parallel bands, gradients, or zoning patterns depending on how the crystal grew and how it’s cut.

Hardness:

7 to 7.5 on the Mohs scale – durable enough for most jewelry applications.

Luster:

Vitreous (glass-like)

Clarity:

Generally transparent to translucent. Inclusions can occur but may add character or color zoning effects.

Cut:

Often cut in rectangular or elongated shapes to emphasize the color split. Custom and freeform cuts are also popular to enhance the natural beauty of the bi-color pattern.

Origin:

Bi-color tourmalines are found in regions like Brazil, Afghanistan, Nigeria, Madagascar, and the United States (especially California and Maine).

Metaphysical Beliefs:

Believed to harmonize opposing energies, balance emotions, and encourage creativity. Different colors within the stone are thought to enhance different chakras.
