A new way to improve the color, clarity and luster of rubies has been tested by scientists: put them in the microwave. Rubies are among the world's most popular precious gemstones, and are also used in high power switches and sensors. Most natural rubies are not uniform in colour, and sometimes blue patches can be seen in the red stone. This decreases the value of a stone.
