Mineral Of The Day #142: Fire Opal
Mohs Hardness Scale: 5-5.5
- The fire opal, like the other opals, consists of silicic acid with a relatively high water content, was named for its red color, which comes from fine traces of iron oxide.
- Fire opals are not strong gemstones, so earrings, pendants, pins, and tie tacks are the safest choice for wearing them. Opal rings should be worn only occasionally.
- Opals love (and need) to be worn a lot, as this enables the stone to maintain its water balance. Opals absorb moisture from the wearer’s skin and from the air.
- The most significant fire opal deposits in the world lie in Mexico. Because of this, fire opals have become the national gemstone of Mexico!
