The Best Places To Buy Lab Created Diamonds Online

Selected for excellence in customer service, range of choice, return policy, ease-of-use, and overall customer experience. Read more about the selection criteria.

If you are going to buy lab created diamonds online there are not nearly as many to choose from as there are mined diamonds. As of writing there simply aren't very many jewelers investing heavily in lab created diamonds. Lab created diamonds make up less than 1% of available diamonds. Here are some places online where you will find a fairly decent selection. This list of online jewelers is complied by me, a GIA Diamonds Graduate, to help you make an informed choice and see what's offered by some of the world's leading diamond jewelers. Everyone has unique needs so if you are not entirely certain which one fills your requirements please use my free diamond concierge service.

I have given James Allen five stars as it satisfies my criteria as an online diamond retailer that provides outstanding service.

One of the busiest diamond retailers today is James Allen. Founded in 2006 by a team of four this online retailer has become a major player in the diamond universe. James Allen's meticulous attention to detail coupled with a high priority on customer experience and service is why, at the time of writing, more than 150,000 happy couples are now owners of James Allen diamond rings. While James Allen has set the pace for the way diamonds should be sold online there are few competitors that can replicate James Allen's success. This is no doubt due to the fact that the founders' focus from the beginning was on customer experience.
