Boron, which lends a bluish color, and nitrogen, which adds a yellow cast, are common trace impurities. Two volcanic rocks that may contain diamonds are kimberlite and lamproite. Synthetic diamonds are created in a laboratory, and they sometimes begin as a tiny piece of a natural diamond. As the name implies, lab-grown diamonds are created in a laboratory, rather than harvested from nature.
