The jadeite that has been worn for many years has turned yellow instead of green, but this jadeite has the A certificate of the Provincial Jewelry Association. Why does it turn yellow? Will jadeite mutate? Jade worn for a long time will turn yellow because of "variation". Jade is a kind of jade, and it will also "mutate".

Some jadeites will turn yellow and get old after a long time, which is called "variation" in the industry. It is caused by the loose internal structure of some jadeites, the invasion of oil and dust into jadeites or the surface oxidation for a long time. Yellowing and aging affect appearance and value.

The "variety" of jadeite is more common in jadeite with white background and oil green.
