While buying pearls, its color is one of the key factors to understand. Here in this post, we will discuss on how pearl can acquire its natural color. You can find pearls in rainbow of all-natural colors from white to black, blue and also violet!
Do you know from where your pink pearl necklace got these colors in the pearl?
Pearl color is mostly influenced by the color of lip of the mollusk, which is the outer part of the shell. As an example, Tahitian pearls will get their light color to dark charcoal-grey colors from black-lipped Tahitian pearl oyster called Pinctada margaritifera.
Another source of getting color of pearls is from the microscopic pigments inside conchiolin layer. This conchiolin is organic “glue” which holds crystalline aragonite layers. Conchiolin will just cement these platelets together
When conchiolin will be pigmented with brown, grey, reddish-brown, black or any other colors, then this pigment will show through thin crystalline layers for giving appearance of blue, yellow, grey, green, black, bronze, pink and orange colors in surface of pearl.
Lastly, aragonite platelets are microns-thin, semi-transparent, and hexagonal-shaped, which make up the prismatic layers of pearl.
As the white light will strike and penetrate the surface of pearl and also its layers, light beam will be refracted back at viewer in all the spectrum, allowing viewer to see all the colors of rainbow.
This phenomenon can also heavily influence the overtone of pearl or certain faint iridescent colors which are visible over body color of pearl.
Now you can see that each of Golden South-Sea pearls can display varying Golden shades of Golden color intensity, however overtone color lying over main body color will influence the overall color of pearl to the viewer.
Though all the science about the pearls is still in evolving stage, and by now we have a fair amount of idea about how a color of pearl is influenced both due to its environment and also by host mollusk.
We do hope that all the information provided in this post, you must have found it quite fascinating and the science about the pearls and also their unique colors will continue to amaze and astonish us.
