Zircon is a very spread-out mineral as almost microscopic crystals or nodules, specially in volcanic rocks, granites, etc. These crystals are very important in geological research. For example, its radio-active degradation due to the frequent presence of small quantities of uranium, allow researchers to date, with extraordinary precision, the age of the rocks that surround them. It is also a gem much appreciated in Asia due to the variety and beauty of its colours. Zircon crystals from this deposit caused sensation when they first appeared on the market a few years ago, because of their beauty.
