There are several influences to the body color of a pearl. The species of the mollusk, the color of the mantle tissue implant, and the elements present in the water during culturing can all have an enormous effect.
Pearl body colors used to have a very narrow range available. Before the popularity of Freshwater and Tahitian pearls, there were limited colors available which included white or cream colors which were found in Akoya pearls.
Freshwater pearls have brought more colors to the table, with lavender and pink or peach body colors.
The Tahitian pearl can come in a wide assortment of darker colors, such as dark greens, blues, and black. These colors are becoming more popular in North America due to intense marketing campaigns developed over the years.
For example, there was a campaign for “pistachio” pearls – which is a yellowish green to greenish yellow color–found on Tahitian cultured pearls. The demand for this color soared, and the awareness of the many new pearl colors increased. Tahitian pearls may have overtones that are different to their body color and enhance their beauty.
The consumer now has a great deal more choice than he or she had before. Many of the same colors appear in different types of pearls and with various overtones. For example, white or cream colored pearls occur in freshwater, Akoya, and south sea pearls. The consumer now has the ability to choose based on color and type of pearl and size of pearl type his pearl jewelry.
The deep golden colors available in the South Sea pearls are unique, but South Sea pearls come in white with a variety of overtones. When carefully matched for exact color, overtone, luster and other factors a pair of South Sea pearl earrings can be stunning to behold and extremely flattering.
