FAQs about 2 Carat diamonds

Shape, color, 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 maximize 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.

2 carat oval cut diamond review

Upgrade for my wife

The simplicity that Blue Nile brings to shopping and buying diamonds is second to none. I was able to filter to EXACTLY what I wanted to purchase and the information I needed to make the best decision was readily available. The value I received on the 2 carat oval diamond I purchased far surpassed every jewelry store I visited.

Amazing from start to finish

Me experience with Blue Nile was spectacular from the first call to picking up the ring in person. Everybody was so kind and helpful throughout the entire process. The diamond and setting are so beautiful. Way to go team. 5 star all the way. We thank you very much!

Great Service, Great Diamond

The ring was great. Your staff went the extra mile to have someone pull the diamond from the vault in the middle of the night to answer some questions I had. It looks better than I could have imagined and how could she say no to 2 carats? (she couldn't!)... Also, we took the diamond to a local jeweler to verify that it matched the certificate and of course it did.
