All these factors together make conch pearls extremely rare as well as expensive. Did you know? Natural pearl colour is an important factor that affects the value of a pearl. It has three components: bodycolour, overtone, and orient. In underwater pearl farms, the cultivators carefully insert pieces of mantle tissue and mother-of-pearl seeds or shell beads into the interiors of bivalve mollusks, such as oysters. The animals secrete nacre to coat the irritants, just as they would in nature. The composition and structure of this nacre is essentially identical to that which forms naturally. Global water temperatures are rising, and local habitats are changing, both of which will affect mollusks and could threaten all types of pearl making.

Shape: Most pink pearls are round or nearly round, but they can also come in a variety of other shapes including oval, button, drop, and baroque.
