One of the most famous gemstones today is Ruby. This precious gem is renowned for its attractive red color. The redder the Ruby, the more popular it is, and it has a very high price.

The most valuable Ruby stone today is the Pigeon Blood Ruby. This stone has a very vivid, bright red color. You will see the red mixed with a slight purple light. If graded on the Mohs scale, Ruby scores 9 points, ranked only behind diamonds. But Ruby is more durable than diamond and more challenging to damage. 

According to Western culture, people only use Ruby stones as sacred engagement objects on their wedding day. However, Southeast Asian people consider Ruby stone a potential mineral, and the most significant quantity is in Vietnam and Myanmar.
