Class Ring Mod™ Gemstone Ruby


Ruby is considered by many as the most precious colored gemstone. The name ruby comes from the Latin word ruber, meaning red. Its lively red color is the result of trace amounts of chromium present in its formation.

Ruby is usually facetted to compliment its natural brilliance. It's a hard gemstone with a rating of 9 out of 10. Ruby is considered to be one of the most durable center stone options. This is perfect if you plan on wearing your class ring on a daily basis.
