How do oysters create different pearl colors?

Pearl Color

Oysters can create various pearl colors irrespective of their shell colors.

However, black-lipped saltwater oysters mainly create black pearls, and hardly any other oysters produce black pearls. 

The nacre secreted by oysters is the major component of pearls.

The nacre secreted by the oyster often takes the color of the outer shell and oyster lips, which eventually form a colored pearl.

Silver-lipped saltwater oyster creates white pearls with bright white overtones while black-lipped saltwater oyster creates black pearls with silver overtones. 

The extent of the thickness of the nacre can also cause oysters to create different colors.

The thickness and quality of a nacre influence the surface quality and luster of pearls as well as its overtones.

The marine environment of the oysters can also influence the different pearls' color in relation to the nutrients and trace elements present in the water. 

What determines pearl color?

Pearl Color

Many factors determine the different pearls' color created by oysters:

❖The type of oysters is freshwater or saltwater oysters. 

❖The amount of nacre layers present; the more the nacre, the thicker the nacre, and the brighter the pearls' color.

❖The quality and thickness of the nacre layers; thin nacre lining produces less lustrous pearls. 

What is a nacre?

Pearl Color

A nacre is an organic crystal-like substance or mineral that is secreted by oysters on the inner shell linings in response to irritants, foreign substances, and parasites that attempt to enter inside the oyster shell.

In oysters, the nacres are secreted in layers, and over time, multiple nacres are formed, which results in pearls.

What's that color under those layers of nacre?

Pearl Color

One characteristic feature of pearls is their iridescent nature, which occurs as a result of the thick layer of nacre.

When light shines on the nacre, it exudes different colors, causing the eyes to see various colors.

Depending on the nacre and oyster shell, there are different colors formed by the layers of nacre. 

The conchiolin, an organic substance present in pearls that is also responsible for the different pearl colors, also reflects its colors under the nacre, showing various colors. 

Pearl buying tips

Pearl Color

Generally, pearls are expensive; however, naturally occurring colored pearls are more valuable and expensive than cultured ones.

Natural pearls are also very rare and comprise multiple nacre layers, which most cultured pearls do not rarely possess.

Rare colored and exotic colored pearls are more treasured than pearls with regular colors which makes them much more expensive. 

Before buying pearls either in a jewelry shop or in a mall, there are some tips to consider;

❖Although choosing pearl colors is more of a personal preference, there are some pearl colors to take note of.

Multi-colored pearls are perfect accessories to compliment your casual and fun look. For your formal wear and evening attires, black colored pearls are a perfect match for your outfit.

For a touch of feminine but sophisticated and elegant look, soft colors like pink/peach pearls, white pearls, and lavender pearls are good pearls to wear. 

❖Do not hesitate to ask the jeweler about the type of pearl you want to purchase.

Some pearls are cultured and dyed to resemble naturally colored pearls, and unless you're told, you might conclude that they are naturally colored pearls.

This is very common among pearls with deep and exotic colors such as Aubergine, Black, Cherry, Gray, and Pistachio colors. 

❖Always observe the strand of pearls you want to buy and once you notice that it appears uniform, check closely because the pearls are likely to be treated with color dyes.

To confirm this, you can check the drill holes of pearls for residual dye content.

Conclusion

Pearl Color

Oysters can create various pearl colors ranging from white and black, which are very common, to rare colored pearls like gold, blue, pink, yellow, and multi-colored pearls.

The color of the oyster shell, the thickness of the nacre, and the oyster environment, however, determine the variant colors.

Do well to compliment your casual and formal look with multi-colored pearls the next time you're starting; they speak elegance!
