There are a lot more to 1-
carat diamond ring's price than just the 
stone’s weight.
You should understand that the 
carat weight is just one of the 4 C’s that mainly affect the price of a 
diamond, 
color, 
clarity, and cut being the other three. Besides, 
carat does not proportionately affect 1-
carat diamond ring prices. For instance, the collective price of three 1 
carat diamonds will be much less than a 3 
carat stone. In fact, the price of 
diamonds goes up with the number of 
carats.
Generally, the cost of a 1-
carat diamond ring in the US ranges from $3,000 to 

$27,500. As said, this huge variation in the price range is because of the other three factors – 
color, 
clarity, and 
cut. A
 round brilliant cut diamond of IF 
clarity and D 
color will be a very expensive purchase, but it will be much affordable if you go for an 
oval cut stone of 
VS2 clarity and 
H color – the
 carat weight in both instances still being the same 1 
carat.
