An extraordinary collection of Star rubies will go under the hammer at–Guernsey‘s auction house in New York City.

Smoky Mountain Two Star ruby
The 86.56 carat Smoky Mountain Two Star ruby is unusual in that stars are visible on both the front and the back of the gemstone.

I find the star rubies to be exotic and romantic. Reminiscent of the gems worn by Hollywood stars in the 30’s and 40’s.

Star rubies are the rarest variety of ruby. Stars are more commonly seen in blue sapphires, the luminous star pattern displayed when the gem is cut in a cabochon shape and viewed under certain lights is the result of an optical phenomenon known as asterism. It is inclusions of tiny, needle-like fibres of rutile in the gem that create the distinctive star effect, with six evenly proportioned rays being the most desirable.

What makes this collection truly amazing for me is that it was found in Appalachia North Carolina. Usually they are found in far off places like SriLanka or Burma. This Mountain Star Ruby collection is home gown and 100% Appalachia.
