Commitment to jewels
The collaboration jewelry features colorful gemstones directly purchased from around the world by gemologists. In addition to the five types of gemstones that were well received in the first series, we have carefully selected high-quality gemstones such as rubies, blue sapphires, and aquamarines.
Among them, the main center stone of the Charmy Premium Model is the pigeon blood ruby, which, as its name suggests, is a top-quality ruby with a deep red color like the blood of a pigeon. It has a strong internal glow and a vivid luster.
Akoya baby pearls, which are shaped like a heart, require advanced techniques to cultivate, making them difficult to produce commercially and meaning that baby pearls are rarely available on the market.
The fancy color pink diamond that decorates the center of the ribbon is a vivid and intense color to create a special feeling. Furthermore, a purplish pink (Fancy Intense) color was selected to give the jewelry an adult and sophisticated look overall.
Additionally, the side stones used in all models are D to G color, H&C, or VS class equivalent. VS class is a diamond with good transparency and fine inclusions that can be just barely seen under 10x magnification, the level used by experts for grading. Of the 23 grades, only colors ranging from the highest D color (completely colorless and transparent) to the fourth grade G color (almost colorless, with a yellowish tinge that is difficult to detect with the naked eye) are used. H&C (Hearts & Cupids) is a diamond in which a heart and arrow can be seen in the shape of a diamond due to the reflection of light.
We have packed this product with thrilling attention to detail, even in the small details that are difficult to notice at first glance.
These gemstones are turned into jewelry by skilled Japanese craftsmen, whose techniques have been honed through years of experience, making this collaboration a reality.
Enjoy the authentic jewelry that only a jewelry specialty store like KARATZ can provide.
