Diamond Foundry is one of the world's largest manufacturers of artificially created Diamonds. These are not synthetic Diamonds, these are *real* Diamonds, just artificially created. These Diamonds take away the controversy of "Blood Diamonds" that are mined unethically around the world. Their production process is also environmentally friendly compared to typical Diamond mining practises. Many big name investors in this company, but one stand out is good ol' Leonardo DiCaprio. They have a Flagship store in Hongkou, but they want foreigners to visit their highly curated show-room, an enclave inside of their Shanghai Headquarters in downtown.
