Diamond Carat

Diamond carat weight may not be able to fully and accurately reflect the size of the diamond, just like people with same weight can have different heights. BDD Co. recommends that carat weight should be considered in conjunction with two other criteria: Diameter of diamond crown (top) (in millimeters) and diamond cut grade.

  • Purchase Tips

    We view a diamond from the top when it set into a ring, so this part is very important.

    Diamond with well-cut has the proper proportions which can reflect the maximum amount of light (or sparkle) out of the top, thus, the reflected light from the top makes it appear larger. In addition, for the poor cut diamond, much of the weight may be “concentrated” in the base of the diamond, making the diamond appear smaller than its actual carat weight would suggest. Thus, a diamond with lower carat weight but higher cut grade may appear larger than a diamond with larger carat weight but poor cut grade.

References Before You Buy

It is very important to measure the budget before buying diamonds. The following are suggestions for you to choose the size of diamonds:

When choosing a diamond carat weight, consider the size of the wearer's finger, the size of the setting, and your budget.

Diamond appears larger on smaller the finger. A 1 carat diamond looks much larger on a size 4 finger than a size 9.

If you have a limited budget, and a larger carat weight is important to you, consider a diamond with an I or J color, SI1-SI2 clarity and good cut grade.

Diamonds of the same size are placed on the bases of various styles and various inlays. The visual effect will be different. Please be creative to choose an exclusive diamond ring for her.
