Unlock your inner-adventurer with a Rare AAA Mexican Fire Agate Gemstone Necklace in Hammered Sterling Silver! Iridescent hues glimmer across the rainbow-landscape of this fire agate - an opal-like sparkle with everyday-wear strength. Formed in the neck of hot springs and geysers, these phenomenons are only found in the Sonoran desert of the SW US and Mexico, and only a select few show their brilliance when cut by a master. What's most stunning is the way color moves within the stone - your own personal dragon's scales or boiling cauldron!
