There is a tale that goes as follows; a little girl, no more than 10 perhaps, received a stone from her grandmother. The girl was embarrassed for carrying a rusty rock with her but kept it with her at all times for the sake of her grandmother. One day the little girl wandered off a trail and lead herself into the forest where she got lost and scared for her life. While thinking of a way to get back, she took out her stone without much thought.
The moment she took it out, a fairy sprung from the nearest Dahlia flower patch and started admiring the stone held by the frightened girl. The fairy was so moved by the intense beauty of the stone, having not seen such an enchantment in a millenium, that she kissed the eyes of the girl as a gift for showing her something so enticing and divine, promising that she will now see beauty in things that mere humans couldn't even dream of.
Suddenly the girl blinked her eyes open and realized she had been deep asleep and was just dreaming all along. She reached for the stone under her pillow and was stunned to discover a gleaming opal that was so vibrant that it seemed like there was colors dancing on it. The girl gawked in awe at the beauty of the opal that she had initially dismissed, now infatuated with the striking opal. Such an opal was recreated to rest upon your finger, recreating the gentle and utopian feeling of the tale.
