[#] 14 [Myth] All rubies are valuable. [Fact] 
Some rubies look like gravel and that is true for any gem material. But there are some natural rubies that have been extensively treated to fill in cracks and cover inclusions that make them far less valuable than merely heated treated rubies or the much more esteemed all natural rubies. Even all natural rubies must be over one carat then have very good clarity and color to be valuable.
