Jewelry became pretty popular in the past years, especially because Luxury brands established a huge business on it. The value of craftmanship and genius is far away one of the aspect that can make the difference in designing and producing jewelry. I think Garni is one of the most respectable brands in this area. Relatively young they have a wide range of products which goes from classic gold jewels to experimental and innovative designs.
Distribution is very limited and it’s difficult to find outside of Japan. you can buy thru Gentei that ship to Europe.
