Watermelon Tourmaline (ウォーターメロントルマリン, Uōtāmeron Torumarin) is a Gem who has only appeared briefly. They're shown to have patrol duty and is partners with Hemimorphite.


They have a pink and lime-green color scheme and wears either a winter or summer uniform depend on season. They also wear the standard black shoes but no gloves nor socks. Their hair is long and looks voluminous. It's pink and flower-shaped near their head, but lime green for the rest. The pink color also extends to their eyes.


Energetic and excited, always has their head in the clouds.


Watermelon Tourmaine has mostly been a minor character, though they do have a few important scenes. They were seen along with other Gems in many common scenes where the Gems did activities together. They became more prominent later in the story when a new type of Moon Person appeared. Watermelon, Bort and the other Gems battled this new type and saved Phosphophyllite, Cairngorm, Sphene and Peridot from being taken to the Moon. In the battle with this double sunspot, Watermelon Tourmaline conducted electricity to defeat several Lunarians. Later, they made flower crowns for Phos and Cairngorm during the Winter Delay arc.


Not much can be said about Watermelon Tourmaline since they are a minor character. When Phos was believed to have turned into a slug and Diamond asked the other Gems for help, the Gems made a variety of responses, though Watermelon Tourmaline stayed silent and let their partner Hemimorphite answer instead.
