The original bicolor tourmaline specimen is as if divided exactly in half into green and red-pink halves. The crystal was actually formed in nature in such a way that different colors alternate in it. From the point of view of mineralogy, the "watermelon" two-tone coloration can be considered a rarity and a tidbit for collectors. The fact that tourmaline contains inclusions has practically no effect on its cost because the main thing for this stone is an interestingly distributed color. The mass of bicolor tourmaline is 3.05 carats. Brazil.
