FAQs about 2 Carat Diamonds

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.

Carat refers to a gemstone’s weight rather than its size. 2 carat rings are a great choice for many engagement styles. They’re popular in many different diamond shapes and typically offer a substantially sized gemstone. Whether you choose a round brilliant or fancy-shaped diamond, a 2 CT stone is a great choice.

Any shape looks great as a two carat diamond ring. Popular shapes for this weight include oval cut diamonds, round diamonds and emerald cut diamonds. Any shape will shine as a 2 carat diamond ring

Halo engagement rings are a timeless choice for maximizing sparkle. A circle of halo stones is the perfect accompaniment for this gemstone weight.

At Blue Nile, we’re proud to offer an impressive selection of ethical diamonds. We only offer diamonds that adhere to the strict standards of the Kimberley Process. Finding your conflict-free engagement ring fit is as simple as browsing our loose diamonds for sale.

Diamond prices increase substantially at half and full carat marks, which is why many people choose to “buy shy” and purchase a gemstone that’s just below their desired weight. After all, carat does not equal size, so purchasing an ideal cut diamond that’s just shy of the 2 carat mark can be a great choice. For example, if you’re looking to purchase a 2.5 carat diamond ring, you may opt for a 2.4 carat stone instead to get a lower price with greater sparkle.

CTW refers to carat total weight, which accounts for all the stones on a ring including the main diamond and any accent diamonds. Settings with halos or pavé accents will often have a CTW value. Because smaller diamonds are typically less expensive than larger ones, a 2 CTW ring will often cost a lot less than a 2 CT diamond ring. But the look of these two rings will be vastly different. If you are looking to purchase a larger diamond for your partner, consider a 2 CT ring rather than a ring’s total carat weight.

2 carat engagement rings are available in a variety of settings to match every style. Whether you’re searching for solitaire, halo, vintage-style engagement rings or any other look, we offer custom options for the perfect ring.

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 jewellery store I visited.
