Rough diamonds are diamonds in their natural state, as they were removed from the depths of the earth and prior to undergoing the polishing process which lends the stone the glitter and luster that characterize diamonds in the eyes of the general public.
To the uneducated eye, rough diamonds look more like shards of glass washed up on the beach: They are oily and dull, and come in colors ranging from yellow through green to brown. Their price is lower than that of Polished Diamonds. In order to bring out the rough diamond’s breathtaking beauty, a professional polisher must first cut and polish the stone.
