2 Carat Diamonds

The 4Cs of diamonds can all affect the final price of a 2 carat diamond. 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. Our diamond carat size chart will help you compare the size of each shape.

Diamond cut is one of the most important of the 4Cs for loose diamonds of any size. Cut impacts how large and brilliant a gem will look in 2 CT diamond rings and other jewelry settings.

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 or just above two carats. So rather than buying 2 carat solitaire diamond rings that have the exact whole carat weight, consider buying a ring with a diamond that’s just above or below the two carat mark. Diamonds just above or below the 2 carat mark are incredibly popular.

Carat refers to a gemstone’s weight rather than its size. 2 carat rings are a great choice for many engagement rings. 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, diamond earrings or a diamond solitaire necklace.  

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

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.
