The FTC requires all diamond under HPHT to be labeled as such.

Synthetic colored diamonds are also available. They are chemically the same as natural diamonds but are created in a laboratory. The key to making diamond was discovered in 1950, when diamonds were synthesized almost simultaneously by Swedish and American researchers.
