Is the diamond certified?

Yes. The center stone is IGI certified and the certificate is included with your purchase, so the carat weight, color and clarity are independently verified.

How are lab grown diamonds made?

They are grown from a diamond seed using HPHT or CVD technology, which recreates the heat and pressure that form diamonds in the earth producing a real diamond in weeks instead of billions of years.

Can a lab grown diamond be told apart from a mined diamond?

Not by eye even trained jewelers can't distinguish them without specialized lab equipment. They have the same brilliance, fire and hardness as mined diamonds.

Do lab grown diamonds get cloudy or lose their sparkle?

No. A lab grown diamond is a true diamond 10 on the Mohs hardness scale so it never clouds, fades or dulls with normal wear.

What metals can I order this ring in?

Every piece is available in 925 Silver, 10K, 14K or 18K solid gold (white, yellow or rose) and Platinum. Gold color is a free style choice it never changes the price.

Can I customize this design?

Absolutely. We can adjust the center stone shape, carat, metal, or add engraving. Message us before ordering and we'll share a CAD/render for approval before production begins.

How long does production and shipping take?

Your piece is crafted and quality-checked in 2–4 days, then shipped with free insured U.S. shipping and full tracking.

What is your return policy?

We offer 30-day returns on standard pieces. Fully custom pieces are made uniquely for you and are non-returnable, except for manufacturing defects.

What if the ring size isn't right?

We offer free resizing within the first 60 days, so your ring will fit perfectly.
