Mountain Star Ruby Collection

Star rubies are the rarest variety of ruby.

I discovered the unique qualities of star gemstones when I was researching Carole Lombard’s brooch - shown above.

Star gemstones were all the rage during the height of Hollywood film industry. These gems made popular by the Hollywood stars who wore them in the 30's and 40's. During our research for the making of the Carole Lombard reproduction brooch we discovered several star ruby gemstones.

The star in the image below is rather strong and bright. This type of star is found in nature. Capturing the intensity in glass was very difficult.

Stars are more commonly seen in blue sapphires than in rubies. The luminous star pattern is 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 fibers 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.
