Peafowl stone ( 孔雀石 )

Peafowl stone ( 孔雀石 ) in Japan

If you say Peafowl stone (孔雀石, Kujyaku-ishi in Japanese) in Japan, there are two meanings.

One is malachite, a copper carbonate hydroxide mineral, with the formula Cu2CO3(OH)2. This usage is a mainstream.

The other usage is minor but indicates stones which have several concentric circles patterns on the surface mined from Japan.

Because the several concentric circles patterns look like an eye-spotted "tail" or "train" of covert feathers of Peafowl, the stone are called Peafowl stone.

Actually, there is a variety of Kujyaku-ishi in the minor usage.

Such as Gojyoume Kujyaku-ishi ( 五城目孔雀石 ), Neo Kujyaku-ishi( 根尾孔雀石 ), and others.

By the way, there is another type of stone which has several concentric circles patterns on the surface. It is Dapples stone(鹿の子石, Kanoko-ishi), kind of Tsugaru Nishiki-ishi. The name is because a pattern of dapples are found on the surface, however, patterns from both Peafowl stone and Dapples stone are very similar and difficult to distinguish.

The following is quote from緋山酔恭の山水石美術館 as a picture of Gojyoume Kujyaku-ishi ( 五城目孔雀石 ):

As regards concentric circles patterns, it is come up to the surface with certain carving and trimming.

If it is not trimming, it is difficult to see the concentric circles patterns from rough stone.

Instead, granular or pimples patterns are found on the surface.
