Because of the rarity of naturally occurring pearls, a process of cultivating pearls was introduced in the early 1900s. In this process, a small bead of polished shell is inserted into an oyster or mollusk to act as an irritant and produce a pearl, which can take up to 24 months. These pearls are referred to as cultured pearls. Pearls are classically elegant and never go out of style.
Types of Pearls
Pearls are produced in a variety of colours, as noted in the types of pearls. Most range from white, cream, and yellow to pink, silver, and black. Most pearls will have both a primary colour, the first colour you will notice, and a secondary colour, the overtone you notice when you take a closer look. Colour variation does not decrease the value of the pearl, but is important when matching pearls to be used in strands, earrings, bracelets, etc.
