Since beginning reforestation work in Costa Rica in 1993, Diamond Tropical Hardwoods has supplied and handcrafted sustainably sourced tropical hardwood products, with a particular focus on teak planters, garden pieces, lumber and custom woodwork. The family-owned company operates a Pennsylvania warehouse and uses a direct supply chain, while directing purchases toward planting more trees. Its lumber carries FSC certification with chain of custody, and its teak planters use marine-grade stainless steel hardware for outdoor durability.
