4 Carat Round Cut Lab Grown Diamond Engagement Rings

Carat Weight

4 carat diamonds are bigger than the average engagement ring diamond and are sure to make a statement and impress your significant other. The large size of your diamond will be very noticeable and make it stand out among the others

Shape

Round cut diamonds (also called brilliant-cut diamonds) are revered for their classic shape and incredible sparkle. Cut with 58 facets — or 57, if there is no culet — the round shape was designed to produce as much sparkle as possible. As sparkle is what many people are looking for when they buy a diamond, round cuts are immensely popular.

60% of the diamonds in our inventory are round-shaped, making it easy for you to find the right one for your needs. Not only are round cut diamonds the most sparkly, but they are also the most popular diamond shape. However, because they are the most sparkly and the most popular, this makes them the most expensive diamond shape.

Round cut diamonds are perfect for custom jewelry, such as earrings and pendants. To make your round cut diamond appear even larger, choose a halo setting. Or let your round cut diamond stand out on its own in a solitaire setting.

Lab Grown Diamonds

Lab grown diamonds are real diamonds that are created in the lab instead of deep inside the earth's crust. They are physically, chemically, and visually identical to earth grown diamonds and are indistinguishable even by a trained gemologist.

The only difference between lab grown diamonds and earth grown diamonds is how they were created. Earth grown diamonds are created under high pressure and temperature deep under the earth's surface, while lab grown diamonds are created under high pressure and temperature(HPHT) in a lab

Lab grown diamonds are typically between 30 and 50 percent cheaper than earth grown diamonds! Therefore they have become a very popular choice for engagement ring, since you can get a bigger size diamond for your budget.

All Ritani lab grown diamonds are certified. Most of our lab grown diamonds are certified by IGI, the most respected independent lab diamond grading labaratory.
