MITUBACI engagement rings are made with natural diamonds of the grades used in our custom-made products. 0.1 ct. to 0.3 ct. diamond grades are available in F color or better, SI-1 or better, and triple excellent or better. 0.5 ct. is available to suit your budget. You can choose the grade of diamond that best fits your budget. A certificate of authenticity is also provided as a proof of quality.
Diamonds are measured by international standards called the 4Cs, which are an objective way of evaluating diamonds: Carat, Color, Clarity, and Cut.

A carat is a unit of weight of a diamond; one carat is 0.2 grams. MITUBACI Tokyo offers 0.1ct, 0.2ct, 0.3ct, and 0.5ct diamonds.

Diamonds are classified between D (colorless) and Z (light yellow); MITUBACI Tokyo offers diamonds with F color or higher, which is classified as "colorless".

Clarity is an evaluation of a diamond's transparency. It is broadly divided into six categories. In descending order of evaluation, they are FL, IF, VVS, VS, SI, and I. They are further divided within each category, comprising a total of 11 grades.

The GIA Diamond Clarity Scale has six categories, some of which are subdivided, totaling to 11 grades.

MITUBACI Tokyo offers diamonds that are SI-1 (inclusions can be seen under 10x magnification) or higher.

Cut is an evaluation of a diamond's balance, symmetry, and polish. While color and clarity are the innate properties of a diamond, cut is an evaluation of the workmanship. The cut is divided into five grades: Excellent, the highest grade available at MITUBACI Tokyo, and Triple Excellent, the highest grade for overall evaluation, symmetry, and polish.

  • Diamonds of 0.2 ct. or more come with a certificate of authenticity booklet from the CGI. While diamonds of 0.1 ct. do not come with a certificate of authenticity booklet, a simple certificate of authenticity is available upon request.
  • While workshop participants can complete most of the ring-making process by themselves, our artisans will take over the stone setting process as it is more complicated.
  • All diamonds provided by MITUBACI Tokyo are natural diamonds.
