When a large amount of fine mineral called rutile is grown inside the sapphire, the top of the gemstone polished to a convex shape will show six stars. This kind of sapphire is called the same as the star sapphire. Ruby also has this effect. The connotation brings starlight but reduces the transparency of the gemstone, so the star red sapphire is usually translucent to transparent, and the surface of the gemstone has a silky silky texture that is very charming. People are not demanding the color of the star red sapphire, but there is still a certain criterion for starlight: Is the intersection of the six stars of the gemstone in the center of the gem? Is the star line complete and bright? Will the star line move with the light and fingers? The more positive the answer, the greater the value of the gem. The bright red and blue star gemstones are the most valuable. If the star line meets the above conditions and is more transparent, the value is very high.
