Violet is a kind of purple jade, which is generally lighter in purple, like purple of purple flower, hence its name. When it is matched with other colors, we usually call it Toona sinensis. So Toona sinensis actually means purple. Careful observation of purple jadeite shows that its hue is slightly different, generally speaking, it can be divided into pink purple, eggplant purple and blue purple. Pink purple with fine texture and good transparency is rare, eggplant purple is inferior, and blue purple is generally coarse, which can be further called purple beans. Purple jade, usually seen in yellow light, will appear purple, so be careful when buying it. Jade with deep purple, fine texture and high transparency is very rare, so it is especially favored by Europeans and Americans. Bean is a very vivid name. We know that jadeite is a kind of polycrystal. If the crystals that make up jadeite are thicker, such as more than one millimeter, they can be easily seen by naked eyes. Coarse jadeite crystals are mostly short columns. When these short columns are clearly defined, they look like mung beans, so they are called bean seeds.
