Blue Opal is associated with balancing metabolism, helping with mineral absorption and iron deficiency, and easeing fatigue.
 
Peruvian Opals are relatively rare and are the national stone of Peru.  Peruvian opals don't have the same fiery play of light as other opals, they have a random crystalline composition and possess a delicate iridescent quality.  Blue is the most common color and may contain black dendritic inclusions.
