1.5 Carat Princess Cut Lab Grown Diamond Three Stone Engagement Rings

Carat Weight

1.5 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

Princess cut diamonds are truly distinctive due to their 90-degree angles and sparkling facets. A modified brilliant cut with a square shape, the emphasis with the princess shape is on bold, modern lines, and lots of brilliance. Princess cut diamonds are a beautiful choice for engagement rings, earrings, and pendants.

Although it was only invented in the 1980s, this diamond cut is one of the most popular choices for engagement rings. For a perfectly square princess cut diamond, choose a diamond with a length to width ratio of 1.00 - 1.05.

The sharp corners of princess cut diamonds are prone to chipping, so choose a setting that will protect the diamond’s corners. To make your princess cut diamond appear larger, choose a halo setting, or let it 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.
