Euclase 3.941ct Ruth Japanese-German Appraisal
Euclase's name comes from the Greek words "eu", which means "well", and "klasis", which means "to break". As its origin suggests, it has a perfect cleavage. Because it is a rare species, it is a rare stone that is rarely made into jewelry. There are color variations such as white, colorless, light green, light blue, and dark blue. A refreshing mint green, like a clear lake that is still a little cold in early summer. It has such beautiful colors that you will forget the time and be absorbed in it. I feel that the sparkle, which captures the eye while giving a sense of ephemerality and delicacy, reminds me of the excitement and excitement I feel when encountering something new.
Comes with a large Japanese-German gemstone laboratory measuring 3.9ct.
