Jet Black pearls with silver, dark green and various shades of gray undertone are quite spectacular. In nature, it is quite difficult to find black pearls – pearls are rarely formed by Pinctada margaritifera oysters. It is way easier to find cultured black pearls, although it is relatively rare and costy and exclusive.
Black pearls are formed when that piece of sand gets stuck in the body of a very specific type of oyster. The interior shell of most oysters is usually a glossy white or silver.
Even if each mollusk is potentially capable of creating a pearl, the stimuli necessary for this are not included in most clams. Normally, only one out of ten thousand oysters produces a pearl. A black pearl appears in the body of one oyster of fifteen thousand. The color of the pearl depends on the color of the liquid that the oyster produces and which hardens around the grain of sand forming a pearl.
Noways, most of the black pearls are grown in the lagoons of the Pacific and Indian Ocean. It may take up to 5 years to give birth to a fabulous black pearl.
Glitter is often the most important factor that experts assess when considering a pearl.
Another important factor is the pearl’s shape. Everyone knows, that pearls are live creatures and its shape may be very diverse. Actually, almost perfect spherical shapes of pearls are very rare, which dramatically increases their value. Well, there might be a reason why round pearls were considered the most valuable for many centuries.
Since black pearls are very beautiful themselves. That is why, when choosing black pearl jewellery, it would be better to stick to minimal design of the metals surrounding the pearl: that will not distract attention from the natural beauty of the pearls.
