, พลอยวรินทร์ ) is a very rare principally girly, but very seldom boy's first name. The given name พลอยวรินทร์ is characteristic of South-eastern Asia, particularly Thailand, where it is a rare predominantly girly, but very infrequently masculine name. Much less frequently, พลอยวรินทร์ is the last name as well as the forename.
