Diamond Supply Co was founded in 1998 in San Francisco by Nick Tershay AKA 'Nicky Diamonds’. The brand started out as a skateboard company, but then expanded to apparel too. Keep an eye out for graphic prints, music references and bright colors within this preowned selection on Depop. Pick up a never-worn Diamond Supply Co hoodie to throw over your casual looks. Or scout out a secondhand t-shirt that will become your new favorite.
