Diamond
Hojudo also wholesales gemstones, so we always have over 300 diamonds in stock, including rare, high-quality diamonds such as IF (internally flawless) and FL (flawless) before they hit the market, diamonds with GIA certification, large diamonds over 1 carat, colored diamonds, and fancy cut diamonds such as marquise, cushion cut, and heart shape diamonds.
Diamond quality standard “4C”
The "4Cs" were established by the Gemological Institute of America (GIA) and are the international standards for evaluating the quality of cut diamonds for jewelry. Diamonds are evaluated based on four criteria: color, clarity, weight (carat), and polish (cut), and are abbreviated as "4Cs" from the initials of each. The 4Cs are listed on a diamond's "certificate."
Custom made is also possible
You can choose your own certified diamond and choose from the designs listed (products marked "Customizable/Remodelable Design"), or you can create an original design from scratch.
