This stone became popular almost at once mostly because of its unique blue color, which could be of all shades of blue, from light to dark. Often Dianite has patterns that resemble clouds. Spheres from Dianite look like mysterious distant planets.
The stone was named Dianite after Princess Diana. Its structure is similar to one of nephrite (Dianite is in fact an amphibole), which is why it is often called blue nephrite or Siberian blue jade, though, as scientists say, this is not a proper name for this mineral. Unfortunately, this beautiful material comes from the mine only in very small amounts. Rough good color is very rare and quite expensive.
