Pliny the Elder wrote in 75 BCE that opals "display at once the piercing fire of rubies, the purple brilliancy of amethysts and the sea-green of emeralds, the whole blended together and flashing with a brightness that is quite incredible…while others speak of it as resembling the flame of burning brimstone.” In fact, the word "opal" comes from ancient Byzantine Greek word, opallios, which means "to change color." 

These 3mm natural opals are veined with fire, shifting from white to blue to red as the light catches. 

10mm keshi pearls are suspended from a delicate chain, and each pair can be made to order in solid gold.
