Ct means carat, and 1ct is equivalent to 0.2g People often say that "minute" is the next unit of carat, 1ct = 100 minute. 0.0 1 1CT diamond is not big, and it belongs to broken diamond with average grade.

One carat is divided into 100, such as 50 cents, or 0.5 carat, which is used to calculate smaller gems. Because the density of gems is basically the same, the heavier the gem, the bigger the volume.

The bigger the diamond, the rarer it is. So the price of diamonds will increase with the increase of carat weight. However, even if two diamonds weigh the same, their values (and prices) may be quite different.

origin

Every diamond is a miracle created by time, the earth and nature. Every diamond is unique, just like every snowflake has a different shape. Until the mid-20th century, there was no universally applicable diamond quality rating standard. GIA Gemological Institute of America initiated the diamond grading standard recognized by the industry today.

The 4C standards formulated by GIA include color, clarity, cut and carat weight. Nowadays, 4C standard has been widely used in diamond quality certification all over the world. The establishment of 4C standard unifies the global measurement standards of diamond quality, and enables consumers to accurately understand the quality and characteristics of diamonds they buy, which is of great significance.
