This nine gram watermelon tourmaline from Afghanistan is actually double terminated. The bottom termination is a little crude as it grew into something. I bought a parcel of these pieces for cutting into slices some years ago. I could not bring myself to cut this one even though I can probably get more for the slices than I am asking for the specimen. 2.5 x 1.3 x 1.3 cm. Everyone loves watermelon tourmalines...it is too bad so few are being found these days. By the way, many people use the term watermelon for any red (or pink) and green tourmaline. A true watermelon tourmaline should be green on the outside with red (or pink) inside....like this one.
