🔹 Japanese Origin | Akoya Sea Pearls, Mata Tama Pearls
Akoya pearls are the most representative type of sea pearl, known as "Akoya" in Chinese. They are primarily cultivated in regions of Japan such as Mie, Kumamoto, and Ehime, with the Seto Inland Sea coast being particularly renowned. Akoya pearls are produced by the **Pinctada fucata** oyster. Due to the oyster's small size, each shell can only yield one pearl, and it requires approximately 3 years of meticulous cultivation, making the yield relatively scarce, and thus, their quality and price are high.
Akoya pearls are nucleated pearls with extremely high roundness. Their luster is cool, brilliant, and bright, earning them the nickname "little light bulbs" in the pearl world and making them highly favored in the high-end jewelry sector. The surface often exhibits natural "orange peel" textures. If you choose a special grade (accompanied by a Japanese certificate), they are nearly flawless with even more translucent luster. Colors include Sakura pink, snow white, blue-pink, cool blue tones, iridescent gold, and queenly colors. There is also the rare Mata Tama color series, a variation of Akoya with a natural purplish-pink sheen, highly sought after by collectors.
🔹 Chinese Origin | Freshwater Cultured Pearls
China is the world's largest producer of freshwater pearls, with production concentrated in Zhejiang, Hunan, Jiangsu, and Anhui. Freshwater pearls are mainly cultivated from large bivalves like the triangle sail mussel, where a single mussel can produce dozens of pearls simultaneously, resulting in a much higher yield than sea pearls. In the past decade, with significant advancements in cultivation techniques and selection standards, high-quality freshwater pearls have achieved levels comparable to Akoya in terms of roundness, nacre compactness, and luster.
Although nucleated, top-grade freshwater pearls can achieve near-perfect roundness, a warm and translucent luster, and strong surface sheen, all at a more accessible price point. They are an excellent value choice for everyday wear and designer jewelry.
Regardless of whether you choose Akoya sea pearls or Chinese freshwater pearls, all products are crafted in our Chinese processing workshops, ensuring that every piece, from raw material to craftsmanship details, meets jewelry-grade standards, adding elegant quality to your daily life.

Unsure whether to choose freshwater or Akoya pearls?
Here's a comparison:
I. Origin & Cultivation
Akoya Pearls
Akoya pearls are a type of sea-cultured pearl, primarily from Japan, but also cultivated in Vietnam and China. The Akoya oyster is the Pinctada fucata, which thrives in marine environments with high salinity and complex currents. Typically, one oyster yields only one pearl.
The cultivation cycle for Akoya is relatively long, about 3-5 years. Akoya's annual yield is low, accounting for about 10% of the global pearl production (total sea pearls). Akoya was the world's first commercially produced sea-cultured pearl, beginning in the early 1900s. Sea-cultured pearls (including Akoya) are usually nucleated, with a spherical bead core inserted into the oyster.
Freshwater Pearls
Freshwater pearls are cultured in freshwater environments like lakes and rivers, mainly in the lakes and rivers of China's Yangtze River basin, such as Zhejiang, Hunan, and Jiangsu. The main oysters for freshwater pearl cultivation are the triangle sail mussel, and a single mussel can yield 10-40 or 30-50 pearls. Most freshwater pearls form naturally within the oyster without a bead core (primarily beadless cultivation), which often leads to irregular shapes. The cultivation cycle for freshwater pearls is relatively short, about 1-3 years.
Freshwater pearls account for the vast majority of global pearl production, about 95%. Nucleated freshwater pearls are also known as "Edison" pearls. Natural pearls and beadless cultured pearls are almost entirely composed of nacre.
II. Appearance - Shape & Size
Shape:
Due to the insertion of a spherical bead core during cultivation and a relatively thin nacre layer that helps maintain roundness, Akoya pearls typically achieve a very round shape with a high rate of perfect roundness.
Over 90% of high-quality Akoya pearls are nearly perfectly round. The Akoya pearls consumers encounter generally have good roundness.
Freshwater cultured pearls (mainly beadless) are naturally formed without a bead core, making their shapes more prone to being oval or irregular. Over 80% of freshwater pearls on the market are oval, flattened oval, or baroque shapes, with a low proportion of perfectly round ones. Because they are beadless, perfectly round freshwater pearls are extremely rare; near-round is the highest roundness grade. Nucleated freshwater pearls (Edison pearls) are similar in size to sea pearls but have lower roundness.
Size:
Akoya pearls are smaller, with pearls typically ranging from 6-9mm. Commercial production is often in the 6-8mm or 5-8mm range. 8mm is considered a good size, with the largest Akoya reaching 10-11mm.
The larger the size of an Akoya pearl, the more precious it is. Even a difference of 1mm, such as between 7-8mm and 8-9mm Akoya pearls, can result in a significant price difference.
Freshwater cultured pearls typically range from 5-12mm in diameter. Nucleated freshwater pearls (Edison pearls) can reach 12-20mm. South Sea pearls are commonly 10-16mm, with those exceeding 16mm being relatively rare and precious.
III. Appearance - Color
The body color of Akoya pearls is mainly white. Common overtones include pink, light greenish-blue, and light yellowish-green, with pink being the most popular. Akoya also comes in blue tones (like Mata Tama) and yellow tones (like Iridescent Queen, Iridescent Gold). Sea pearls (including Akoya) do not have purple. Pearl colors originate from minerals or natural pigments secreted by the oyster.
The colors of freshwater cultured pearls are mainly white, pink, and light purple. Purple is a unique color for freshwater pearls, derived from carotenoids in the triangle sail mussel. Nucleated freshwater pearls (Edison pearls) can exhibit deep purple and bronze colors. Freshwater pearls do not have pure black or deep gold colors. Some colors may be bleached or dyed.
IV. Appearance - Luster
Pearl luster is a crucial factor in determining quality, even its soul. Luster is related to the thickness and quality of the nacre layers. The stronger the luster, the more precious the pearl, and the higher its price. Luster is the most important value factor of a pearl.
Akoya pearls are known for their very high and beautiful luster, earning them the nickname "little light bulbs of the human world." Their luster is strong, capable of sharp reflections and clear imaging. In comparisons of the highest quality, Akoya's mirror-like luster can reach levels higher than South Sea pearls. High-quality specimens can reflect a human face.
The luster of freshwater cultured pearls is relatively softer, primarily diffuse reflection, like soft silk. Some high-quality freshwater pearls can achieve good luster, reaching 70%-80% of that of sea pearls. Some higher-grade freshwater pearls can achieve "extremely strong luster." The luster of freshwater pearls is shallower, with weaker refractive effects. GUILD classifies pearl luster into four grades: Very good, Good, Fair, and Poor.
V. Appearance - Surface Quality
Naturally produced pearls usually have some surface imperfections. The fewer imperfections a pearl has, the better its quality. Absolutely flawless pearls are extremely rare and expensive.
Akoya pearls have a higher surface smoothness, with imperfections mostly being small pinpricks.
The surface of freshwater pearls may show growth lines such as spiral patterns and indentations.
Surface quality is divided into four grades: Very good (near flawless), Good (minor imperfections), Fair (moderate imperfections), and Poor (many imperfections). The degree of imperfection is one of the factors in determining pearl quality.
VI. Physical Characteristics - Nacre Thickness & Durability
Nacre thickness is an important factor in assessing the quality of nucleated cultured pearls. Nacre thickness affects the pearl's beauty and durability. If the nacre is too thin, it can affect luster, and prolonged friction may cause it to lose luster or even "peel."
The nacre layer of Akoya pearls is relatively thin compared to other types of sea-cultured pearls, typically ranging from 0.15mm to 0.55mm. 0.5mm is considered a thick nacre for Akoya. According to GUILD standards, Akoya with a nacre thickness greater than 0.4mm is of better quality. Akoya is most sensitive to nacre thickness. Akoya's thinner nacre layer helps it maintain a rounder shape.
The nacre layer of freshwater cultured pearls (mainly beadless) is usually 0.3 to 0.8mm. The internal structure of beadless freshwater pearls is almost entirely composed of nacre. Prolonged wear of freshwater pearls may gradually cause them to lose luster due to friction, resulting in a relatively shorter lifespan. Nucleated freshwater pearls (Edison) have thicker nacre layers, reaching 0.8-3mm.
Overall, sea pearls have thicker nacre layers and longer lifespans. The nacre layer of sea pearls (such as South Sea pearls, Tahitian pearls) typically ranges from 0.8-3mm. South Sea pearls can have a nacre thickness of up to 2mm, which is 60 to 100 times that of Akoya.
VII. Daily Wear & Suitability
Due to their high luster, roundness, and classic white tones, Akoya pearls are a very popular choice for everyday wear. They are suitable for versatile necklace styles, exuding elegance, nobility, and classic charm. They are also suitable for formal occasions, weddings, and business gifts.
Freshwater cultured pearls, due to their affordable price (thanks to China's high production volume and cultivation methods) and diverse colors (especially baroque shapes), are a popular choice for daily commutes and casual wear. High-quality freshwater pearls (extremely strong luster, near-round, very minor imperfections) are visually indistinguishable from sea pearls to the naked eye, offering excellent value and are very suitable for everyday wear. They are ideal for students, new professionals, or baroque pearl enthusiasts. If you have a limited budget and primarily wear pearls daily, high-quality freshwater pearls are an excellent choice. From a purely functional perspective, there is very little difference in the wearing experience between high-quality freshwater pearls and sea pearls.
