Chairman's Notes

Because opal has the colors of other gems, the Romans thought it was the most precious and powerful of all. This is a feature that led the Roman naturalist Pliny the Elder to describe precious opals in his Natural History as if they were all the gemstones combined into one: “This most beautiful of gems combines the fire of the ruby, the brilliant purple of amethyst, and the sea-green of emerald; all shining together in glorious and incredible union.”
