The 3 carat princess cut diamond ring offers a contemporary and chic alternative to the classic round cut, with its sharp angles and clean lines delivering a modern aesthetic.

In contrast, a 3 carat princess cut diamond engagement ring stands out for its perceived size and value, offering a larger surface area than round diamonds of the same carat weight, yet it may not have the same sparkle as a well-cut round diamond.

A 3 carat oval diamond ring offers a unique elongated shape that can make the finger appear more slender, and its brilliant faceting style enhances its sparkle compared to other cuts.
