Blue Nile becomes exclusive US retailer of Royal Asscher diamonds

Blue Nile, the division Signet Jewelers has positioned as the top of its portfolio, became the exclusive North American retailer of Royal Asscher diamonds and jewellery through a multiyear licensing agreement disclosed on Monday. The deal puts six patented Royal Asscher cuts and two recently launched collections on Blue Nile's site.

The two collections now available are Curated by the Asscher Family and Six by Royal Asscher. Joan Hilson, Signet's chief financial and operating officer, framed the agreement as central to Blue Nile's effort to concentrate on natural diamonds and establish itself as the portfolio's premier luxury jewellery brand.

Hilson told WWD the partnership would help Blue Nile cement an elevated position in the diamond jewellery market. She said the brand's intention is to be natural diamond leading, focused on the enduring value of a natural stone. Other gemstones and lab-grown diamonds will still be sold.

Why Blue Nile is leaning on natural diamonds

The emphasis on natural stones reflects where revenue is arriving. Hilson said ninety percent of engagement rings priced above $5,000 are natural diamonds, and that demand is being driven particularly in the engagement market. Blue Nile is therefore concentrating on growing that side of the business.

The Royal Asscher move is the latest of several initiatives Signet has run through Blue Nile to lift the brand. The Clear Cut, a concierge service offering gemologist guidance on diamond purchases and proprietary technology, was acquired earlier this year.

James Allen, bought by Signet around a decade ago, has also been folded in. It became a proprietary brand on the Blue Nile website while jamesallen.com was shut down. That consolidation pushed more of the group's online diamond trade under a single name.

In August, Pam Cloud joined Blue Nile after nearly 26 years at Tiffany and Co., most recently as senior vice president and chief merchandising officer. She is a 30-year veteran of the jewellery industry and now leads merchandising for a brand Signet wants at the top of its hierarchy.

Signet's brand ladder

Hilson described the intended pecking order plainly. The top of the house would be Blue Nile, then Diamonds Direct, then Jared, with Kay and Zales serving the mid market. That ordering is the stated goal of Signet's broader brand strategy.

The Blue Nile work falls under Signet's Grow Brand Love strategy, which aims to differentiate four core brands, Kay, Zales, Jared and Blue Nile, with more design-led assortments, a stronger bridal business, centralised functions and some consolidation in pursuit of efficiency and agility.

Cloud said Blue Nile has for more than two decades transformed diamond shopping through transparency, innovation and trust. She called Royal Asscher one of the most respected names in diamond craftsmanship, and pointed to Curated by the Asscher Family as a mark of trust.

That mark, she explained, reassures customers that stones have been cut for the most beautiful light return possible. The framing ties Blue Nile's long-running transparency pitch to the Asscher family's own emphasis on cutting, rather than grading, as the measure of a diamond.

The Asscher family and its heritage

The Royal Asscher Diamond Company was founded in Amsterdam in 1853 and has been run by six generations of the Asscher family. It pioneered the Asscher Cut, and in 1908 Joseph Asscher cleaved the 3,106-carat Cullinan Diamond, the largest gem-quality rough diamond ever discovered.

Some stones cut from the Cullinan are in the British Crown Jewels, a heritage Hilson sees as usable in the American market. She said there is some level of familiarity with the Royal Asscher name and a significant opportunity to market it in the US.

Hilson argued that being the exclusive retailer and putting Signet's scale behind the Royal Asscher name is what will grow Blue Nile overall. The exclusivity itself, rather than simply carrying the product, is the point of the arrangement in her telling.

Lita Asscher, copresident of Royal Asscher, said Cut for Beauty is not a new idea but a philosophy that has shaped six generations of diamond innovation. She noted that in 1902 Joseph Asscher designed the original Asscher Cut, a diamond design recognised around the world.

More than a century later, she said, the family's responsibility is not simply to preserve that heritage but to keep innovating. Her brother Mike Asscher, also copresident, said the family's six patented cuts draw on generations of knowledge about proportion, symmetry, light and beauty.

Mike Asscher framed the work as a continuing question: not simply what a stone's grade is, but whether it is beautiful. That is what Cut for Beauty means to the family, he said, and it is the standard Blue Nile is now licensed to retail exclusively.

No start date for the collections was given in the announcement, and neither side disclosed the financial terms of the licensing agreement. Hilson added that Signet will use its scale to market the Royal Asscher name to American customers, who she believes already recognise it to a degree.
