The vast majority of diamond engagement rings that are popular today have small to very small round diamonds, called melee, used as accent stones. They can be set in a band, accenting a solitaire diamond center stone or set completely around a center stone in a halo style ring. A large majority of diamond melee purchased by jewelers have inconsistent clarities, colors and cut grades, and ultimately are set in the jewelry they produce. Nathan Alan uses diamond melee that are consistently cut with the very best technology. Every diamond is made proportionally consistent in each and every dimension. The idea behind purchasing these ideal cut diamonds is to give our customers the most beautiful diamonds possible delivering the highest possible brilliance, fire, and sparkle. You are likely to find these special cut diamonds set in watches from the top brands in the world such as Rolex, Chopard, and Audemars Piguet.

Nathan Alan rings are handcrafted and custom made to order by our elite quality craftsmen. They are all designed based on the shape and exact measurements of the center stone selected. All of our rings are available in Platinum, 18k white, yellow, or rose gold. Nathan Alan’s standards of quality and craftsmanship and attention to detail when paired with our ideal cut diamonds results in a product that outshines all others with unmatched beauty. Experience the Nathan Alan difference.
