Many of the diamonds on our site are a part of our exclusive inventory. However, some of the diamonds listed are from third-party vendors who sell their diamonds on our site as well as other sites. Because of this, you may purchase a diamond on our site and later receive an email that the diamond is no longer available. You will be notified within 48 hours if the diamond is no longer available. This slight delay is because many of our diamond vendors are internationally based, creating a time difference.
When a diamond is no longer available, we will work with you to find a similar diamond. You will not be charged for anything until the order ships.
Engravings can be added to the girdle of the diamond using lasers. Please note that engraving a diamond will make it final sale. If you are interested in engraving your diamond, please contact our customer service team.
You can request for a diamond to be reserved. Just contact our customer service team at 1-888-9RITANI or chat online now.
It can take up to 48 business hours to receive HD diamond images.
Lab-grown diamonds are physically, optically, and chemically identical to earth-grown diamonds. They can cost up to 30% less than mined stones, which makes them ideal for someone on a tight budget. Even if you’re not on a tight budget, you can get more bang for your buck by choosing a lab-grown diamond.
