Danburite is a rare stone that was first discovered in the town of Danbury, Connecticut. This beautiful gemstone has also recently been found in Japan, Burma, Madagascar and Mexico. In recent years, Danburite has become very popular as a jewelry stone instead of white diamond as the color is identical, but the size is much larger and incredibly much more affordable than a diamond. Danburite has a hardness of 7, which makes it perfectly suitable for all types of jewellery.
