Legend has it that Indra once cast the five precious minerals:

1. gold, 
2. silver, 
3. coral, 
4. pearl, and 
5. sapphire or turquoise, into the great ocean. 

These were eventually consumed by various cattle animals such as the

1. bull, 
2. cow, 
3. ox, and 
4. yak , 
5. elephant

which then formed bezoars within their bodies. They have different colors and potencies based on the animal they originate from.
