Diamond K Supply, Ltd. 3671 Mount Diablo Boulevard, Lafayette, CA 94549

"Easy delivery options, the guys are always nice for a large or small order. I'm a Realtor in town and always pop by with lots of random questions. Ordering is the same whether you spend $100 or $5000. I really like the staff. Easy to park, easy to navigate. We are lucky this is right in town."

"Kevin, Oscar and the entire Diamond K Team are always extremely helpful! Their dedication to hard work is one of the only things that allows Halcyon to function at the high level of output that we do, while keeping consistency with their great products! Thanks again Diamond K!!!!"

"It's less and less common to have such a great resource like Diamond K close by. For landscape professionals and homeowners alike it's a godsend. They stock everything you'll need to develop a landscape except low voltage lighting and wood for decks and fences etc. If you need stone, boulders, brick, slate, soil, decomposed granite drainage rock and pipe, filter fabric or weed barrier or irrigation parts or masonry supplies and tools...etc.. etc... you are in luck! They have much more than that as well I'm certain. They deliver and are open early. The staff are knowledgeable and kind. Shop Local. We need businesses like Diamond K to remain!"

"Diamond K carries varieties of rocks, bricks, gravel, decomposed granite, and landscaping tools and supplies (i.e. for drainage, irrigation). The guys who work there are very helpful and knowledgeable. They deliver locally."

"If you need rocks of any kind or size, this is the place! Wonderful selection, great prices and the service is even better. Update... They seem to now not really care. So sad they used to be much better. Their prices are higher now, too."
