This invention relates to synthetic garnite tiles made essentially from garnite sand and a process for the production of synthetic garnite tiles essentially from garnet sand which is a by-product of beach sand from rare earths extraction, said process comprising mixing beach sand garnet, feldspar and clay thoroughly; pressing the mixture using a press at a pressure in the range of 40-80 MPa to form tiles of desired shapes and sizes; drying the tiles so formed at a temperature of 100-120.degree. C.; firing the dried tiles at a temperature in the range of 1050-1250.degree. C. with a soaking for a period ranging from 1.5 to 2.5 hours, and polishing the resultant tiles.
