3 Carat Radiant Cut Lab Grown Diamond Three Stone Engagement Rings

Carat Weight

3 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

The radiant cut is a stunning hybrid of other diamond shapes - it resembles the rectangular silhouette and cropped corners of an emerald cut diamond, but with more sparkle.

Radiant cut diamonds have a modified brilliant cut, making their sparkle similar to princess cut diamonds. Radiant cut diamonds currently make up 3.3% of Ritani's diamond sales.

It's a sophisticated choice for those who want a more extraordinary diamond shape, but still with that classic sparkle. The elongated silhouette of radiant cut diamonds will make your diamond appear larger and will make your finger appear longer and more slender.

Stars who have worn radiant cut engagement rings include Jennifer Lopez and Drew Barrymore. Radiant cut diamonds are also a beautiful choice for custom jewelry, such as pendants and earrings.

Radiant cut diamonds are typically rectangular in shape, but they can also be square. For a square radiant cut diamond, choose a stone with a length to width ratio of 1.05 or less. For a rectangular radiant cut diamond, choose a stone with a length to width ratio of 1.20-1.35. Choose a length to width ratio that is appealing to you - there is no correct one.

If you want to add additional sparkle, choose a halo setting. This can also make your diamond appear larger. Or let your radiant cut diamond stand out on its own with 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.
