Round Lab Grown Diamond Ring

Throughout the centuries, this alluring diamond shape has been the most popular diamond outline. The reason is actually quite straightforward. The round diamond shape with its 58 (or 57) facets produces the most eye-popping brilliance and light performance of any diamond. It simply out-sparkles the competition.

Then if you pair that classic shape to a lab grown diamond, you’ve given the ring an extra boost of glamour. Lab grown diamonds, while being an ethical choice are also produced in high colors and clarity. So, the stunning diamond ring you’ve always dreamt of is within reach budget-wise. Since lab grown diamonds are more affordable than their natural counterpart, consumers get a bonus of being able to select higher clarity and color stones while often being able to purchase larger stones than they thought they could afford with an earth-mined stone. You’ll find many smart shoppers today opting for round brilliant cut lab grown diamond rings because of these benefits. A classic looking round cut lab grown diamond will look as stunning decades from now as it did when you first put it on—that’s reason enough to consider this popular option!
