Diamond quality begins in the fertile soils of California’s Central Valley and other nut-producing regions. Diamond’s grower-owners use the very latest, environment-friendly farming practices. Constant attention is paid to the orchards, from pruning to irrigation to harvest.

Come fall, the nuts are shaken from the trees and swept into bins. Their hulls are removed and the nuts are dried, and then they make the short journey to the Stockton, California facility. There, each nut is carefully selected, sorted and cleaned before shelling and packaging.

Processing Steps

Nuts go through a series of processes before they’re ready for your favorite recipe or holiday nut bowl. Some steps, such as cracking, shelling and chopping, are carried out for your convenience. Some are carried out for the sake of appearance, such as the polishing of pecans. Still others, among them state-of-the-art laser sorting, cold storage and quality monitoring, ensure that the nuts you buy are orchard fresh year-round and wholesome for your family.

Diamond Facilities

Diamond products are processed and packaged at facilities in Stockton, California; Fishers, Indiana; and Robertsdale, Alabama. Approximately 50 percent of the California walnut crop passes through the doors of the Stockton plant each year, the largest and most technologically advanced such plant in the world.

Diamond facilities in Alabama and Indiana process Brazil nuts from the Amazon, along with top-quality in-the-shell walnuts and almonds from California, hazelnuts from Oregon, and pecans from the southeastern United States. In addition, Diamond has four seasonal receiving facilities in California: Live Oak, Linden, Modesto and Visalia.
