Since the 1930s, Akoya pearls have been among the most renowned worldwide. Known for their typically round, spherical shape and exceptional luster, these pearls are produced by the small oyster Pinctada fucata, found in the seas of Japan and China. They generally range in size from 2mm to 10mm. The pearl industry has long cherished Akoya pearls and are often the preferred choice for brides on their wedding day.

Tahitian pearls, also known as black South Sea or simply black pearls, are highly esteemed for their remarkable exotic colors and mirror-like luster. Unlike other types of pearls, which typically come in limited colors, Tahitian pearls exhibit vast overtones, showcasing breathtaking hues such as peacock green, silver green, blue, and aubergine. These pearls are produced by the Pinctada margaritifera oyster, found exclusively in Tahiti and a few other islands in French Polynesia.

White and golden South Sea pearls are highly prized for their classic colors and exceptional sizes. These rare gems are produced by the large oyster Pinctada maxima, found in deep offshore waters. White South Sea pearls are commonly found along the coast of Australia, typically exhibiting a creamy white color with silver overtones. High-quality golden South Sea pearls are usually sourced from the Philippines, with a color range that spans from light gold to deep gold.

Mabe pearls, named after the mollusk Pteria penguin (also known as the 'penguin shell'), are called 'mabe-gai' in Japanese. These cultured blister pearls differ from other cultured pearls in their growth process. Unlike traditional pearls that develop inside the mollusk’s body, mabe pearls form inside the shell. This results in a pearl with a domed shape and a flat back, which is why they are sometimes called 'half-pearls.' Mabe pearls provide the allure of South Sea pearls with a large, magnificent dome at a more affordable price. Their flat backs make them popular for elegant earrings, rings, and pendants.

Conch pearls are beautiful and lustrous, formed from calcium deposits produced by the Queen Conch (pronounced 'conk'), a large edible sea snail. The highest-quality specimens are typically pink and oval-shaped, featuring a wavy 'flame' structure on their surface. They have a creamy, porcelain-like appearance and unique luster.

Unlike pearls harvested from oysters, conch pearls are non-nacreous, similar to other natural pearls (including melon and giant clam pearls). This means they are not composed of nacre, the substance that gives traditional pearls their iridescent sheen. Therefore, technically, they are not considered 'true pearls,' though they are still referred to as 'genuine pearls.'

Today, most pearls are cultivated by introducing irritants into mollusks and controlling their growth. However, conch pearls are a completely natural phenomenon with no human intervention.

Harvested by teams of fishermen, a single elusive conch pearl can be found in every 10,000 to 15,000 shells, with fewer than 10% being gem-quality. This rarity, combined with their unusual colors, makes conch pearls highly sought after.
