Golden Caramel Rock Southern California Quarry. This rock is a beautiful golden and tan caramel colors with patches of chocolate and small amounts of white quartz crystals. This rock is also improperly called Navajo Gold and Mesa Gold by local gravel and landscape supply yards. This 3/4" screened gravel is great for larger portions of the landscape. In smaller landscape and garden planterbeds the 3/8" minus or screened material usually offers better scale of size and a finished look. See more landscapes with this gavel visit our Pinterest page
