What Is Watermelon Tourmaline?

What Is Watermelon Tourmaline?

Many stones remind us of the elements of summer.

Amber and honey calcite remind us of the hot summer sun. Turquoise of the teal blue waters that cool down our senses.

We have malachite whose rich green hues remind us of lush foliage. Watermelon tourmaline, with its blend of pinks and greens, resemble the juicy summer fruit after which the crystal was aptly named.

Watermelon tourmaline is the most famous multi-coloured tourmaline variety. Gem laboratories often call it bi-colour tourmaline, but many people have come to associate its colours to the rind and flesh of a ripe watermelon that the stone has eventually become known as the watermelon of the crystal world.

This post gives you a slice of the crystal's properties and history. Read on to know more!


The Physical Properties of Watermelon Tourmaline

Watermelon tourmaline displays colours similar to a ripe watermelon slice. It has a hot pink to red core covered by a light to dark green exterior. These 2 colours are often separated by a thin band of white or pale pink. Cutting the crystal into thin slices (rather than faceting it) reveals this eye-catching colour zoning.

Tourmaline is rated 7 to 7.5 on the Mohs hardness scale. This makes it a durable stone for jewellery. However, tourumalines have a complex crystal structure which causes them to crack during the cutting process when areas of tension in the crystal are not identified.

Watermelon tourmaline's unique colour patterns make it a sought-after stone for designers and crafters. Coloured tourmaline gemstones are known for their pleochroic properties. So when viewed at different angles, they change colours. Some tourmaline varieties have a strongly visible pleochroism than others.


The History of Watermelon Tourmaline

The name “watermelon tourmaline” was coined by the Norwegian naturalist George Robley Howe. It was officially used in a news publication in Maine in 1910. Eventually, watermelon tourmaline became the trade name for the bi-coloured crystal.

Tourmaline deposits are found in veins in rocks created by molten magma from volcanoes. Large rocks that form after the cooling of the magma are filled with a solution of water and minerals (lithium, manganese, or iron), which then become tourmaline crystals.

What causes the dual colours and colour zoning in watermelon tourmaline?

These happen when the concentration of lithium and manganese change during tourmaline's crystal growth. When pink tourmaline forms and is exposed to additional minerals lithium and manganese, it changes its colour to green. Hence, the pink centre and green exterior.

While colour zoning can result in the crystal having a core of 1 colour and an exterior of another colour, it can also occur across the length of the crystal. Some tourmalines can have 15 different shades or colours.

Watermelon tourmaline is mainly found in Afghanistan, Brazil, Madagascar, Nigeria, and the USA
