A Princess cut lab diamond is square on the top, features four beveled sides and comes in at a point (like an upside-down pyramid) beneath the shiny surface of the ring. If you want maximum sparkle in a modern design, this is the ring cut for you. The clean lines keep the ring looking contemporary. The princess-cut diamond was invented by Betazel Ambar and Israel Itzkowitz in 1980.
Princess cuts are also a popular alternative to round brilliant diamonds in studs.
