Blue Nile Is Now Selling Engagement Rings With Lab-Grown Diamonds

For years, Blue Nile refused to sell lab-grown diamond engagement rings, but it is now selling them alongside real diamonds on its website.

Although De Beers' Lightbox brand of lab-grown diamonds has long been marketed by Blue Nile, engagement rings have not been among their previous uses. Signet purchased the online retailer in August. The inventory of Blue Nile seems to be a little different from that of some of its rivals. Since the high-pressure, high-temperature (HPHT) approach is thought to be more effective at manufacturing high-color diamonds than the chemical vapour deposition (CVD) method, it appears to be selling a lot more D-color diamonds. China is where most HPHT diamonds are produced. Although Blue Nile officials initially claimed that the site's average sale was approximately $10,000, a large portion of the lab-grown diamonds in its inventory are priced between $1,000 and $2,000.

In keeping with its custom, Blue Nile also seems to be selling them mostly with GIA reports. GIA has been grading lab-grown diamonds since 2020, but the top laboratory for natural diamonds is not well-liked by lab-grown diamond manufacturers. The trade-in policy of Blue Nile, which states that it applies to "any GIA or [AGS Lab-]graded natural and colourless diamonds acquired from Blue Nile," is not quite clear either. However, it also states that upgrades are offered on a like-for-like basis (e.g. lab grown for lab grown or natural for natural). On a case-by-case basis, upgrading from naturally grown to lab grown or vice versa may be suitable.

The way a diamond interacts with light is determined by its cut rather than by its actual form. A diamond's brilliance and shine are influenced by its cut. It takes precise craftsmanship to cut a diamond so that the stone's dimensions, symmetry, and polish maximise its splendour. In order to stand out from the crowd, modern women are straying from conventional cuts and choosing unconventional ones, such as marquise and trapezoid diamonds.

A Signet spokeswoman informs JCK that Blue Nile's trade-in policy "is being examined as well as part of integration and will likely be comparable to James Allen's." You may view James Allen's trade-in policy here, which applies to both lab-grown and untreated diamonds. The website described its lab-grown diamonds as a "sustainable solution" at the time of print. "We've requested the Blue Nile integration team that is assessing their advertising to delete" the remark about the "sustainable alternative," the representative said.

Specifically mentioning the use of the word "sustainable," the Federal Trade Commission warned lab-grown sellers not to make "unqualified general environmental benefit claims" in 2019. The FTC warned that "it is highly unlikely that they can substantiate all reasonable interpretations of these claims."
