cantera opal
Cantera opal is a type of opal that is the birthstone for October, and refers to opal with a host rock that is mainly produced in Mexico.
Many of them are polished into a round, round, egg-like shape, giving them a unique cuteness.
It is said that the name comes from the Spanish word for the host rock, ``cantera'' (stone quarry).
