A lustrous image of a white round object with subtle iridescence is the first thing that comes to mind when the word “pearl” is mentioned.

Technically, a reject of a bivalve, natural pearls are celebrated as a beautiful gemstone, not only due their rarity but also for their minimum processing for jewelry. Even though, pearl culturing gave access to much more common and affordable products. Iridescence, specifically “orient” for pearls has been one of the most desirable features of a pearl regardless of origin.
