Is iprimo a famous brand? What's the quality of diamonds?

I-PRIMO is a customized wedding ring brand in Japan. It is a well-known brand in Japan, and its sales volume is also ahead of many big brands in Europe and America. It can be regarded as a national brand of Japan, and the technology and design of Japan guarantee that all products are sold first-hand, and second-hand diamonds will never be used. At that time, I was surprised when I saw Miss Jelly Lin wearing it. It's beautiful, especially the diamond rings in 12 constellation series, which are very distinctive, not only in design, but also in naming. Later, when I was painting Weibo, I saw the overlapping way of wearing ginger, which was totally planting grass. Later, I bought I-PRIMO's diamond ring, which is still blingbling's for more than a year.
