A Stockton snack line, then Snyder’s-Lance, Campbell and Flagstone.

Emerald is a brand of snack nuts that began inside Diamond Foods, the company that grew out of a California walnut growers’ cooperative. English Wikipedia says the business was founded in 1912 as Diamond Walnut Growers, a member-owned agricultural cooperative; that it centralised its operations in Stockton, California, in 1956; that it took the name Diamond of California in 1999; and that it converted to a corporation and became the publicly traded Diamond Foods in 2005. The walnut and baking-nut name that came out of that cooperative has its own guide, Diamond of California.

Wikipedia dates the launch of the Emerald line of snack nuts to 2004, and the brand’s present owner gives the same year: Flagstone Foods said in May 2023 that Emerald had been providing branded snack nuts since 2004. Wikipedia describes the range sold under the Emerald name in the Diamond years as trail mix and roasted, glazed and flavoured snack nuts, along with other snacks, with 100 Calorie packs among the pack sizes. The brand was run from Stockton in that period; MediaPost’s Marketing Daily described Diamond in January 2007 as a Stockton, California, company and named Andrew Burke, its vice president of marketing, as the executive speaking for Emerald’s advertising.

Emerald then followed its parent through a series of sales. Wikipedia says Snyder’s-Lance acquired Diamond Foods and the companies under the Diamond Foods name in 2016, and that Snyder’s-Lance sold the Diamond of California culinary nut business to Blue Road Capital in 2017. Campbell Soup Company said in a press release dated 30 May 2023 that it had acquired the Emerald nuts business as part of its 2018 acquisition of Snyder’s-Lance, Inc.

That same release announced that Campbell had sold the Emerald nuts business to Flagstone Foods, and said the terms of the transaction were not disclosed. Flagstone confirmed the deal in its own announcement, issued through PR Newswire from Minneapolis on the same day, saying it had acquired Emerald Nuts from Campbell Soup Company. Flagstone Foods has owned Emerald since 2023.

Glazed nuts, grab-and-go packs and a private-label owner.

In its May 2023 announcement, Flagstone Foods described itself as a manufacturer and distributor of private label snack nuts and trail mixes, and listed its plants in Robersonville, North Carolina, El Paso, Texas, and Dothan, Alabama. The same announcement said Flagstone was acquired by Atlas Holdings in 2019, and that in late 2022 it hired Harry Overly as chief executive to accelerate its growth as what it called a snacking solutions provider. Atlas Holdings republished the release on its own news page.

Overly framed the purchase as a new route to the same customers. “Adding Emerald Nuts to our portfolio establishes a new avenue for Flagstone to service our customers with innovative snack products,” he said in the release, adding that Flagstone looked forward to continuing to drive growth for itself and its retail partners. The company described Flagstone as a maker of snack nuts, culinary nuts, trail mixes and other nut-based snacks for retailers in the club, mass, grocery and drug channels.

Flagstone said Emerald was known for items such as grab-and-go 100 calorie packs and assorted glazed nut products; Wikipedia, describing the Diamond-era range, likewise lists glazed and flavoured snack nuts and 100 Calorie pack sizes. Campbell, announcing the sale, described Emerald as the Emerald nuts business it had acquired with Snyder’s-Lance in 2018.

The brand’s website, which in October 2026 carried a Flagstone Foods copyright line, presents the glazed products prominently. Emerald says its Kettle Glazed Pecans are glazed by hand in small batches in flame-fired kettles, and invites visitors to try them for themselves.

Design and documentation.

The brands in this group sell nuts, rice and chilled side dishes, three kinds of food that reach the shelf in very different packages. A nut brand may speak through a tin, a jar or a resealable bag; a rice brand through a printed sack or a box that sits in the cupboard for months; and a side-dish brand through a tray or tub in the refrigerated case, where it is seen for a few seconds beside its neighbours.

In each case the pack carries most of the identity: a name, a colour that can be spotted from the end of an aisle, and often a picture of a place, a farm or a person. Behind that name, the company may have changed owners, moved its kitchens or plants, or grown from a single shop or farm into part of a much larger food group.

Each guide separates what independent sources record from what the company says about itself — its founding story, its owners over time, where its food is made and how its packs and labels have changed — and marks plainly what rests only on the company’s own word.

Goodby, Silverstein and Partners, an acrostic and Robert Goulet.

In the Diamond years Emerald was advertised on television during the Super Bowl. The commercials came from Goodby, Silverstein & Partners, the San Francisco advertising agency. The Associated Press, previewing the Super Bowl advertising in January 2005, ran a still from an Emerald nuts commercial in which a unicorn strolls into a living room. On NPR’s All Things Considered in February 2006, the host Melissa Block said Emerald Nuts had become known for “nutty ads,” and introduced the author Warren Berger, who called this kind of commercial “oddvertising.”

The 2006 spot was built on the brand name itself. The Commonwealth Times, the student newspaper of Virginia Commonwealth University, reported on 6 February 2006, citing the Richmond Times-Dispatch, that the Emerald Nuts commercial shown during that year’s Super Bowl used all of the letters in “Emerald Nuts” to create a sentence and a scene. Stacy Milrany, a senior art director at Goodby, Silverstein & Partners who worked on the spot, told the newspaper: “The client challenged us to be different and bold and brave.”

In 2007 the brand turned to a celebrity. MediaPost reported on 8 January 2007 that Emerald’s Super Bowl spot from Goodby would feature the entertainer Robert Goulet, backed by online, print, billboard and in-store elements. Chief Marketer described the finished spot in November 2007: Goulet shimmies down a rope into a man’s office and wreaks havoc on those who do not take a nut break at 3 p.m., eating a Post-It note, throwing papers and dancing on desks. The same report said Emerald would not run a Super Bowl television ad in 2008. “We will have great retail promotions and really drive our business during Super Bowl,” Burke, by then senior vice president of marketing, said on an analyst call. “We’re just not going to run a Super Bowl ad.”

The brand returned to the big game alongside a sister snack. Radio & Television Business Report wrote on 21 January 2010 that Diamond would show a commercial for both Pop Secret popcorn and Emerald Nuts during CBS’s coverage of Super Bowl XLIV, featuring a flamboyant dolphin trainer on top of a volcano in a marine park who shouts “Let’s Get Aquatic!” before the line “Awesome + Awesome = Awesomer.” Michael Mendes, then Diamond’s chief executive, said in the report: “We have used Super Bowl advertising very effectively over the years to drive broad awareness and growth of our Emerald brand.”

For a design guide, Emerald shows how a brand launched in 2004 used the letters of its own name as advertising material, spelling out “Emerald Nuts” in a scene before moving on to a celebrity spot. Compare it with Diamond of California and Planters. For this guide we use emerald green, deep forest, roasted almond and kernel cream with a geometric sans, an unofficial interpretation; no product or logo is reproduced.
