Sheep-Fat-Oily White Jade is also called Mutton Fat White Jade by some collectors. We know that jade is a beautiful semi-translucent precious stone that is denser than other stones and characterized by shiny, smooth, heavy surfaces and distinct sounds when knocked on. The beautiful characteristics of this work of art have lead to its value as a wonderful decorative keepsake, as well as a great collection for investment, due to the fact that the Ancient Old Jade grows in value as it ages.
