Watermelon Tourmaline Gemstones


Watermelon Tourmaline

Watermelon tourmaline is a concentrically color-zoned tourmaline with red interiors and green exteriors. Compared to longitudinal bi-color or polychrome zonation, pleochroism occurs in all colored Tourmaline stones, making their color vary when seen from different angles.

This effect is subtle in some Tourmaline gems but prominent in others. Therefore, when trimming a Tourmaline, gemstone cutters must keep this in mind so that the finished gem can have the most incredible color possible.

What is the appearance of watermelon tourmaline?

Watermelon tourmaline has banded colors reminiscent of a ripe piece of watermelon. A green rim encircles the red or pink center, frequently split by a sliver of pale pink or white. Brightly colored zones can also be found at each end of the jewel. Watermelon tourmaline crystals have a characteristic rounded triangular shape with vibrant, distinctly differentiated colors, and they are highly uncommon and attract premium prices.

What produces the colors of watermelon tourmaline?

When trace elements alter in concentration or composition throughout the development of a crystal, bi-colored and multi-colored zoning occurs. These unique gems can have colorful zones along the crystal or a center of one hue and an outside border of another. Tourmaline crystals can have up to 15 distinct colors or tints.

Pink and green Elbaite crystals are present in the same stone as watermelon tourmaline, and these color zones give a visual record of its development process. As the watermelon tourmaline crystal grows and deepens, it is exposed to various minerals such as manganese and lithium, causing the gem’s color to shift from a pink center to a pale zone and finally to the green rind.

How Does Watermelon tourmaline Develop?

Pegmatites are the sources of tourmaline. Pigmatites are cavities deep beneath the earth filled with a rich hot liquid rich in various minerals. The minerals crystallize and form Tourmaline crystals when the liquids begin to cool. The host rock is usually granite or schists. Some species can also be found in metamorphic rock, such as marble.

Crystals can grow in one color at the center core and another on the outside rim or with bands of multiple colors along the length of the crystal shaft. Any color combination is available. The most common bi-color gem is “watermelon” Tourmaline, which combines pink or red with green. Bi-color Tourmalines can exhibit varying magnetic responses within the same gem, with pink/red parts being the least magnetic or diamagnetic.

Because they originate in a liquid-rich environment, the inclusions may include trace quantities of liquid trapped within the stone. Iron-rich tourmalines are often black to bluish-black to deep brown, magnesium-rich tourmalines are brown to yellow, and lithium-rich tourmalines can be practically any color: blue, green, red, yellow, pink, and so on. It is only very seldom colorless.
