SIX by Royal Asscher is a fine jewelry collection set with patented diamond cuts, each designed and cut by the Asscher family, who have cut diamonds in Amsterdam since 1854. Every piece features natural diamonds and is available exclusively at Blue Nile. Discover the royal story behind the collection.

The collection includes halo diamond earrings, statement rings, a diamond bracelet, and a diamond necklace. Each piece is built around Royal Asscher diamonds: round brilliants frame the earrings, bracelet, and necklace, while the rings showcase round, pear, and Asscher center stones.

Choose from our assortment of rings, each with a halo-framed center diamond and a diamond-lined band. The Round Brilliant Ring offers classic sparkle, the pear brilliant ring brings a graceful, elongated shape, and the Asscher brilliant ring features the step-cut square shape the Asscher family made famous.

Yes. The earrings, bracelet, and necklace share the same round brilliant diamonds and halo detailing, so they coordinate naturally. Pair the Round Brilliant Earrings with a ring for a signature daily look or add the bracelet and necklace for a full set that makes an occasion unforgettable.

The original Asscher cut was designed by the Asscher family in 1902. It was the first diamond cut ever patented, and its square step cut shaped the Art Deco era. The Royal Asscher Cut is the family's own evolution of that design, with a reimagined facet arrangement, proportions, and symmetry.
