レッドスピネル Spinel is a special gemstone in many ways. For centuries it was mistaken for ruby and gained undeserved fame. Today fine red spinel is more rare than ruby but less valuable. That looks like a delayed revenge for its unlucky past. Its name derivation is also ambiguous. Experts are undecided whether it derives from the Greek word for "spark" or the Latin for "thorn".
Due to its excellent hardness (8 on Mohs scale) and high clarity spinel produces fine jewelry in various cuts and shapes. Spinel is never treated in any way and continues to be a great substitute for ruby and sapphire as well as an outstanding stone in its own right.

Many beautiful gems on the site. Love that you are actually shipped the gem that is shown in the photos. Also cool that they give a write up of each gem detailing hardness, characteristics, and best uses for mounting. Great site! Looking forward to seeing these gems in person.
