Desert Diamonds actually consist of an extremely high grade Quartz, which when correctly cut and treated have the appearance and lustre of far more costly real diamonds. When ‘rough’ they look similar to the pebbles that you would find in a river, except that when held up to the light they are translucent.omething the whole family can enjoy in the fresh air and get a long lasting memento or two, free of charge at the same time. Why not go on a desert diamond hunt. Don’t forget to take a picnic and plenty of water.
