[Be, according to the anime, only Yellow Diamond survives in the end, and the more I write about it, the more depressing it becomes, so I'll write about daily life first]
Red diamond, also known as light red spar, is a variant of round diamond. Spherical in shape, hard and tough, red diamonds are the rarest type of colored diamonds.
Blue diamonds are formed by containing boron atoms in their crystal structure. They are deep and blue. They are second only to red diamonds in rarity and represent the eternal heart.
Yellow diamonds are also called gold diamonds. In addition to yellow and golden yellow, wine yellow and amber are also common. While yellow diamonds are relatively common, fancy vivid yellow diamonds are rare and hard to find.
Green Diamond Natural green diamonds take millions of years to be formed by being exposed to natural radiation and changing their crystal lattice structure. A green diamond often has different shades of green, making it a very rare species.
Diamond is a brittle mineral and will crack along the crystal cleavage planes under moderate impact. The color depends on the degree of purity, the type and content of impurity elements contained, extremely pure ones are colorless, and will emit different fluorescence colors of green, sky blue, purple, yellow-green and other colors under ultraviolet light.
