Choosing your lab-created diamond ring

Are lab-created diamonds real diamonds?
Yes. Lab-created diamonds are made of carbon in the same crystal structure as mined diamonds, so they have the same hardness, sparkle and fire. The only difference is that they're grown in a controlled lab instead of mined.
How do I find the right ring size?
Use our ring size guide to measure at home with a ring you already own or a strip of paper. If you're between sizes, choose the larger one.
What does CT TW mean?
CT TW (carat total weight) is the combined weight of every diamond in the ring, center stone and side stones together.
Which shape should I choose?
Round shows the most sparkle, oval and pear look larger for their carat weight and lengthen the finger, and emerald cuts have a clean, vintage look. Shop by shape.
What if it isn't quite right?
You have 30 days from the ship date to return any new, unworn piece for a full refund, minus shipping and gift-packaging charges. Resized or repaired items can't be returned. Read the full policy.
Is shipping really free?
Yes. Every US order ships free with fully insured FedEx delivery. An adult signature is required at delivery.
