  1. It is 0.421 points, 1 carat = 100 points = 0.421 carat, CT means carat. Clarks was considered a decisive standard for measuring the value of diamonds.
    421 is close to half carats, a little smaller. It can be matched with a custody of snowflakes, which can be more large, and there will be half carat effects.
    In international practice, jewelry dealers generally only be a single one at 0.3CT, that is, diamonds above 30 points or more will be issued. The 4C grading certificate, and our country is based on the national standard, stipulates that the 0.2CT diamonds issue a 4C grading certificate.
