Semi-precious stone countertops are another form of exotic countertops. Being made of semi-precious stones, these countertops offer an exotic look, like no other. Semi-precious countertops are made by individually cutting many semi-precious stones and then binding them together to form a continuous solid surface. The colors and finishing effect depend heavily on the types of semi-precious stones used. To add to the majestic look of the semi-precious countertop, you can opt to add under surface lighting to really bring out the beauty of the stones.
