Pair tourmaline refers to tourmaline crystals that are formed with two differently colored shades growing together in the same crystal. These bicolored tourmaline crystals are quite rare and highly prized by collectors.
The most famous and valuable type of pair tourmaline is called a watermelon tourmaline. It features green colors on the exterior of the crystal and a pink or reddish color at the core, resembling the coloring of a watermelon slice. The contrasting colors are created by different amounts of mineral impurities during the crystal's formation.
Other less common color combinations in pair tourmalines include green and pink, blue and green, and yellow and green hues together. The rarity and unique color zoning patterns make pair tourmalines among the most desirable and expensive tourmaline varieties for collectors and gemstone enthusiasts.
