Watermelon tourmaline in small samples inside a glass jar with a cork lid.
Watermelon tourmaline is characterized by having a pink inner part and a green outer part. When a watermelon tourmaline crystal is cut crosswise, the pinkish color in the center and the green color on the outside can be appreciated.
Colored tourmalines are characterized by their dichroism and, being scarce, are used in jewelry making.
This 4 cm box contains a glass vial with pieces of watermelon tourmaline.
*The price is per unit (a single cardboard box of the four shown in the photo)
