Diamond Carat vs. Cut: Which Is More Important When Buying?
lot of people think that it is better to go for a bigger diamond while saving money on cut, color, or clarity. However, this is not always a good idea.
You should remember that you are more likely to end up with a stone that has visible flaws and whose size makes them even more noticeable. This is especially true with diamonds whose clarity is graded SI2 or I1/I2/I3 as these stones usually have inclusions that can be seen with the naked eye.
In general, if you are about to buy a diamond of clarity lower than VS2/SI1, it is best to go with a smaller stone.
There is another reason to go with smaller diamonds when shopping for low-clarity stones: You are more likely to find a smaller diamond with invisible inclusions that a bigger one.
This is because on average, smaller diamonds have fewer inclusions than bigger diamonds of the same clarity.
You are more likely to find a stone whose flaws are not visible or happen to be placed in a not-so-prominent location if the diamond is small rather than big.
Generally, if you go lower than the VS2-SI1 clarity range, the stones are more likely to have inclusions easily seen with the naked eye.
To get as big a diamond as possible that still looks clean and is as affordable as possible, look for eye-clean diamonds.
In general, buying a higher-clarity diamond that is smaller is a better choice than getting a bigger stone of lower clarity. That is from a purely aesthetic standpoint. It is most important to adhere to this principle when the only way to get a higher-carat diamond is to accept clarity that is so low that the stone has visible inclusions.
