Created by oysters in saltwater environments such as oceans and seas. Popular types include:

Akoya Pearls: Cultivated primarily in Japan and China, Akoya pearls are known for their round shape, high luster, and typically white or cream color.

Tahitian Pearls: Cultivated in French Polynesia, Tahitian pearls are notable for their larger size and distinctive dark colors, including black, gray, and green.

South Sea Pearls: Cultivated in the waters of Australia, Indonesia, and the Philippines, South Sea pearls are among the largest cultured pearls and are prized for their size, luster, and often white or golden hues.

Freshwater pearls are a type of pearl that is formed within various species of freshwater mussels, primarily in rivers, lakes, and ponds:

Chinese Freshwater Pearls: Often available in a variety of shapes and colors, Chinese freshwater pearls have become increasingly popular and are cultivated in various regions of China.

Biwa Pearls: Historically associated with Lake Biwa in Japan, these pearls were initially produced in Lake Biwa, but cultivation has shifted to other locations due to environmental changes.

Edison Pearls: Named after inventor Thomas Edison, Edison pearls are a relatively recent development in freshwater pearl cultivation. They are known for their large size, round shapes, and vibrant colors, making them particularly appealing to those seeking a bold and modern look.

Pearls formed in the wild. Natural pearls are considered rare and valuable due to the unpredictable and uncontrollable nature of their formation. Harvesting natural pearls involves searching for them in the wild, typically by divers. This traditional method is labor-intensive, and the yield of natural pearls is limited. When available, they are highly sought after by collectors and enthusiasts for their uniqueness and historical significance.

Due to the scarcity of natural pearls and the development of cultured pearl farming techniques, the vast majority of pearls available today are cultured. Natural and cultured pearls form through the same processes.

Pearls come in a variety of natural colors, including white, cream, pink, peach, lavender, peacock, and various shades of gray. The color is influenced by the mussel's environment, or can be dyed.

Luster is a crucial factor in a pearl's beauty. High-quality pearls can exhibit a lustrous, iridescent surface. The luster is a result of the layers of nacre and how they interact with light.

Pearls can vary in size, typically ranging from 2mm to 16mm or more. Larger pearls are generally more valuable.

Blemishes, spots, or irregularities. Pearls with a clean, smooth surface are considered more valuable than those with noticeable imperfections.

Nacre is the iridescent substance that forms the layers of a pearl. Pearls with a thick layer of nacre are considered higher quality and more valuable. Thicker nacre tends to enhance the durability and longevity of the pearl.

The geographic origin of a pearl can influence its value. Some regions are known for producing pearls with specific characteristics. For example, pearls from certain Japanese or Australian waters may carry prestige and command higher prices.

Whether a pearl is natural or cultured can affect its value. Natural pearls, formed without human intervention, are rare and often more valuable.

Some freshwater pearls are nearly spherical, resembling traditional Akoya or South Sea pearls. These are classic and timeless, suitable for various men's pearl jewelry styles.

Baroque pearls have irregular and non-symmetrical shapes. They can vary widely and may include twists, turns, and unique contours. Baroque pearls offer a more artistic and organic look, suitable for creative and eclectic men's pearl jewelry designs.

These have a flattened appearance, resembling a button or a disc. Often used in earrings or other designs where a flat back is desirable.

Potato, or 'off round', is a subset of baroque pearls categorized by their nearly-round shape. These pearls often have a slightly textured or dimpled surface, which adds to their natural and organic appearance. The surface imperfections can give each pearl a unique and individual character.

These pearls are small and typically elongated, resembling rice grains or "Rice Krispies." They are available in various colors and are often used in contemporary and casual jewelry designs.
