Appraising Koi other than Gosanke
In the Hikarimono breed too, Fukurin is responsible for the presence of shininess in the skin, that is unique to the breed. The entire body appears wrapped in a distinct shine. The area, which has most sheen is the head. Asagi with solid Fukurin becomes even more beautiful in its color as it starts to turn more lustrous.
There are more beautiful Koi among the Matsunosuke breed with spots of Gin (silver) in their bodies. These silver spots are known as Matsunosuke Gin. Matsunosuke breed tend to develop Gin even during their Tosai period, but in general,Gin becomes more visible around the second year. In number of cases where there would be no Gin during the Tosai period, but suddenly Gin will start to develop in the second year. High quality Koi is good fish regardless of the presence of Gin. Quality of a Koi is high only when it maintains its beauty for a long time.
Like the traditional Japanese bridal kimono, which is woven and embroidered with gold and silver thread; the presence of gold and silver thread is not the quality that determines the ultimate value of the kimono. Indeed, the inherent value of a Kimono does not change whether it has gold and silver threads or not. It is best not to get too involved in the presence of Gin in Koi because one can miss the point. It is more important to confirm the real essential qualities that determine the value of the Koi.
