Diamonds Carat
Do you want to buy a diamond?
You can choose certified diamonds and create your own jewelry. We even offer ten thousand loose diamonds in our diamond database.The picture below compares carat and width in a round brilliant cut diamond. You should, however, take into consideration that the resolution of your screen can influence the actual dimensions. If you would like to have the exact dimensions, please print the following PDF file. Note also that a two-carat diamond is not twice as big as a one-carat stone when you view it from above. The reason for this is that the entire diamond’s volume increases proportionally to the carat. Please note also that the diamond’s price rises progressively. A 2.0 carat diamond is significantly more expensive that two 1.0 carat stones.
Which carat should I choose?
When you choose a carat, you should think about the jewelry style, size of the finger and of course your budget. If the carat you are looking for does not match your budget, we recommend choosing a diamond with a good cut, SI1-SI2 clarity and I or J in color. This is a compromise meaning that you can choose a diamond with a little more carat.To compare the dimensions of a diamond with its weight in carats, see the calculation tables for each diamond cut below.
