Understanding Opals at Their Origin

Early inhabitants of Australia, the aborigines, tell of the Creator descending to earth on a rainbow bringing a message of peace to all mankind. The very spot where his foot alighted became infused with rainbows hues--and thus opals were born.
Still today, it's said that 95% of all opals are mined in Australia. Their story began millions of years back when water and silica covering a vast area of that continent created the perfect storm in which to develop these silica rich natural gems.
Opals are in fact a silica gel, and depending on the specimen, its water content can range from 3 to 10% of the total stone. The mechanism behind Opals' rare and shimmering play of color is traced to the crystal configuration. Remember the multi-hued soap bubbles that fascinated you as a child? Precious opal is structured by microscopic spheres packed closely together. This results in opal breaking up light into its various rainbow colors, a completely different way than how transparent gemstones glisten.
The result; a spectacular light show.
Yael Designs knows a thing or two about spectacular light shows. Take a look at their chic double drop opal pendant. The coup is how they manage to find such exquisitely matched vibrant blue opals to pair into one splendid pendant.
