STAR RUBY -STAR-R1

STAR RUBY 9.5ct opaque cabochon. Rubies are a variety of the mineral corundum, which also constitutes sapphires since they are one and the same save for the red colouring. A ruby is considered a Star Ruby when a three-point or six-point asterism, or star if you will, appears within the stone. This star is created when tiny fibers of rutile, also known as “silk,” have light reflected off of them in such a way that a star shape is formed.
