Diamond

Diamond Supply Co. was founded by skateboarder Nick Tershay (aka Nick Diamond) in 1998 in San Francisco, initially selling skateboard hardware such as bolts and bearings from his apartment. Over time the brand expanded into apparel, accessories, and streetwear while remaining closely tied to skate culture. In 2000 the company moved operations to Los Angeles where it continued to grow. The brand’s visibility soared following the 2005 collaboration with Nike SB on the “Tiffany” Dunk, which played a major role in expanding its reach in both skateboarding and streetwear. The company also established flagship stores on Los Angeles’ Fairfax Avenue and later in San Francisco and New York.

Diamond Supply Co. retains its core identity in skateboarding, emphasizing authentic design, quality materials, and community connection. Signature elements include its diamond logo, Tiffany‑blue accents, and recurring products like heavyweight tees, hoodies, hardware, skate decks, and footwear. The brand remains active globally and continues releasing collections that draw from its heritage while engaging with broader street and skate cultures.
