Shape, colour, cut, clarity, and carat all affect a final diamond price. You can spend anywhere from $5,000 to $60,000 or more on a 2 carat diamond, depending on the shape and stone quality.
Carat doesn't refer to size, but rather weight. The shape of a 2 carat diamond affects the size of the diamond you choose. On average, a 2 carat round brilliant diamond will measure 8.1mm in diameter, while a marquise cut will measure 10.5 mm x 7mm. This diamond carat size chart will help you compare the size of each shape.
The cut grade is the most important of the 4 Cs when it comes to selecting a loose diamond of any size. Our Astor by Blue Nile™ diamonds with an "ideal" cut maximise brilliance by providing incredible light reflection from the many facets of the diamond.
One of the best ways to make your budget go farther is to "buy shy" and look for diamonds that have a carat weight of just under two carats.
