Pearl Essence

Also called essence d'orient. A crystalline substance extracted from fish scales and combined with acrylic resins. Used to make imitation pearls. In better imitations, the essence is applied over opaline glass beads; in cheaper imitations, over plastic beads. Discovered in 1565 by Jaquin, a French manufacturer of rosaries, when he accidentally dipped some pearls into water in which he had washed fish. Refined versions today produce spectacular results.
