Difference Between Pearl And Coral Gemstone- Pearl.org.in

Pearl gemstone and coral stone are quite identical in nature. The reason for the above statement is that both stones are being captured from seawater. And, both are organic in nature.

Moreover, pearls and coral stone is fragile in nature on the moh scale, they barely score 3.5 which is an extremely low number.

Both stones are immensely attractive and widely being embedded in wedding and engagement jewelry.

However, there are certain differences between coral and pearl stone. Hence, in today’s article, we would like to throw light on the differences which exist between coral and pearl stone.

A coral gemstone is formed by living organisms, on the other hand, pearl stone development takes place inside the oyster when an irritant is either intentionally placed or naturally implanted inside the oyster. This blog delves deep into the differences between these two captivating gemstones, exploring their origins, types, cultural significance, and uses.

Origins and Formation

Pearl Formation

Pearls are formed within the soft tissue of a living shelled mollusk, primarily oysters and mussels. When an irritant, such as a grain of sand or a parasite, enters the mollusk, the creature secretes layers of nacre, a combination of aragonite (a form of calcium carbonate) and conchiolin (an organic protein), around the irritant. Over time, these layers accumulate and form a pearl.

The process can take several months to years, depending on the species of mollusk and the environmental conditions. Pearls can be found in both saltwater and freshwater environments.

Saltwater Pearls: Typically come from oysters found in oceans. The most famous types include Akoya, South Sea, and Tahitian pearls.
Freshwater Pearls: Usually come from mussels found in rivers, lakes, and ponds. They are often more irregular in shape compared to their saltwater counterparts.

Coral Formation

Corals, on the other hand, are formed by marine polyps, tiny animals that live in colonies on the sea floor. These polyps secrete calcium carbonate to form a hard skeleton, which over time becomes the coral structure.

Corals grow very slowly, often taking hundreds to thousands of years to form significant structures. The most prized corals for gemstones are found in the Mediterranean Sea and the Pacific Ocean, particularly around Japan and Taiwan.

Types and Varieties

Types of Pearls

Akoya Pearls: Known for their high luster and relatively small size, Akoya pearls are predominantly produced in Japan and China. They are usually white or cream-colored with overtones of pink, silver, or green.
South Sea Pearls: These are among the largest and most valuable pearls. They come in white and golden varieties, primarily harvested in Australia, Indonesia, and the Philippines.
Tahitian Pearls: Often referred to as black pearls, they are actually available in a variety of colors including black, gray, green, and blue. They are mainly cultivated around the islands of French Polynesia.
Freshwater Pearls: Found in a range of shapes and sizes, these pearls are primarily produced in China. They come in various natural colors, including white, pink, lavender, and peach.

Types of Corals

Red Coral (Corallium rubrum): Highly prized for its deep red color, red coral is mainly found in the Mediterranean Sea. It has been used in jewelry for thousands of years.
Pink Coral (Corallium japonicum): Also known as Angel Skin coral, it is valued for its delicate pink color and is primarily sourced from the waters around Japan and Taiwan.
Black Coral (Antipatharia): This coral is notable for its dark color and has been used historically for carvings and jewelry. It is primarily found in deep waters.
Blue Coral (Heliopora coerulea): Known for its distinctive blue color, blue coral is less commonly used in jewelry but is valued by collectors.
