[As our factory is self-sufficient in pearl cultivation and jewelry production, all pearl sizes are produced in limited quantities. Due to the time required for pearl harvesting and potential impacts from cultivation conditions, certain sizes may become temporarily unavailable. Therefore, some styles may experience temporary stock shortages. Please inquire about availability before placing an order.] Our pearls, depending on the variety, are sourced from two major production regions, Japan and China, and are processed in our professional jewelry workshops in China, ensuring stable quality and exquisite craftsmanship to perfectly showcase the pearls' natural luster and charm. 🔹 Japanese Origin | Akoya Saltwater Pearls, True Hanadama Pearls Akoya pearls are the most representative type of saltwater pearls, known as "Agoya" 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. As the oyster is relatively small, each shell can only yield one pearl, requiring approximately 3 years of meticulous cultivation. Consequently, their production volume is relatively scarce, and their quality and price are correspondingly high. Akoya pearls are nucleated, exhibiting high roundness and a cool, brilliant luster. They are hailed as the "little light bulbs" of the pearl world and are highly favored in fine jewelry. Their surface often displays a natural "orange peel" texture. For specially selected grades (accompanied by a Japanese certificate), they are nearly flawless with even more luminous shine. Colors include Sakura pink, snow white, rose-blue, cool blue, aurora gold, and queen color. Additionally, there are rare True Hanadama colors, a variant with a natural pink-purple iridescence, beloved 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 provinces. Freshwater pearls are primarily cultured from large mussels such as the triangle-lip mussel, where a single mussel can yield dozens of pearls simultaneously, resulting in a much higher output than saltwater 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 roundness, nacre compactness, and luster. Although nucleated cultivation is less common, 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 saltwater pearls or Chinese freshwater pearls, all products are crafted in our Chinese processing workshops, ensuring that every piece meets jewelry-grade standards from raw material to craftsmanship, adding elegant quality to your daily life. https://live.staticflickr.com/65535/54586131810_8f2fee49cc_b.jpg (In the Pearl Grading Guide: the circled sections can serve as reference standards for the pearls in our store) https://live.staticflickr.com/65535/54586035868_cf01f90df0_b.jpg https://live.staticflickr.com/65535/54585793436_ddd2e63e51_b.jpg https://live.staticflickr.com/65535/54585797431_701d282b24_b.jpg Wearing and Care Recommendations It is recommended to put on pearls as the last step of dressing, avoiding direct contact with cosmetics or perfumes. Not recommended for wear during bathing, hot springs, swimming, or sports to prolong the jewelry's lifespan. After each wear, it is advised to wipe with a soft, dry cloth and store separately in a velvet pouch to prevent scratches from friction. Avoid wearing with 18k gold gemstones or jade bracelets (e.g., on the same wrist) to prevent scratching the pearls. 💖 Follow us for the latest gemstone product information 📌 Latest arrivals on Pinkoi 💌 If you like specific colors or types of gemstones, feel free to message us for custom orders. Unsure whether to choose freshwater or AKOYA pearls? Here's a comparison: I. Origin & Cultivation Akoya Pearls Akoya pearls are saltwater cultured pearls, primarily from Japan, but also cultivated in Vietnam and China. The Akoya pearl's mother oyster is the Pinctada fucata, which requires growth in marine environments with high salinity and complex currents. Typically, one mother oyster yields only one pearl. Akoya cultivation cycles are relatively long, about 3-5 years. Akoya's annual output is lower, accounting for about 10% of global pearl production (total saltwater pearls). Akoya was the world's first commercially produced saltwater cultured pearl, beginning in the early 1900s. Saltwater cultured pearls (including Akoya) are usually nucleated, with a spherical bead core inserted into the mother oyster. Freshwater Pearls Freshwater pearls are cultured in freshwater environments such as lakes and rivers, mainly in the lakes and rivers of China's Yangtze River basin, like Zhejiang, Hunan, and Jiangsu. The primary mother oysters for freshwater pearls are the triangle-lip mussel, with stable and controllable water quality for growth. One mussel can yield 10-40 or 30-50 pearls. Freshwater pearls are mostly formed naturally within the oyster, without a bead core (primarily non-nucleated cultivation), which leads to more irregular shapes. The cultivation cycle for freshwater pearls is relatively shorter, about 1-3 years. Freshwater pearls account for the vast majority of global pearl production, about 95%. Nucleated freshwater cultured pearls are also known as "Edison" pearls. Natural pearls and non-nucleated cultured pearls are almost entirely composed of nacre. II. Appearance - Shape & Size Shape: Due to the insertion of a round bead core during cultivation and a relatively thin nacre layer that helps maintain roundness, Akoya pearls typically achieve very round shapes with a high rate of perfect roundness. Over 90% of high-quality Akoya pearls are nearly perfectly round. The roundness of Akoya pearls accessible to consumers is generally good. Freshwater cultured pearls (mainly non-nucleated) 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 lower proportion of perfectly round ones. Due to non-nucleated cultivation, perfectly round freshwater pearls are extremely rare; near-round is considered the highest roundness grade. Nucleated freshwater cultured pearls (Edison pearls) are similar in size to saltwater pearls but have lower roundness. Size: Akoya pearls are smaller, with pearls typically ranging from 6-9mm. Commercial production often falls within the 6-8mm or 5-8mm range. 8mm is considered a good size, with the largest Akoya pearls reaching 10-11mm. Larger Akoya pearls are more precious. Even a difference of 1mm, such as between 7-8mm and 8-9mm Akoya pearls, can result in a significant price difference. The diameter range for freshwater cultured pearls is typically 5-12mm. 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 greenish-yellow, with pink being the most popular. Akoya also comes in blue tones (like True Hanadama) and yellow tones (like Aurora Queen, Aurora Gold). Saltwater pearls (including Akoya) do not have purple hues. Pearl colors originate from minerals or natural pigments secreted by the mother 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-lip mussel. Nucleated freshwater cultured pearls (Edison pearls) can exhibit deep purple and bronze colors. Freshwater pearls do not have pure black or deep gold colors. Some colors may undergo bleaching or dyeing treatments. IV. Appearance - Luster Pearl luster is one of the key factors determining quality, even considered its soul. Luster is related to the thickness and quality of the nacre layers. The stronger the luster, the more precious and expensive the pearl. Luster is the most important value factor of a pearl. Akoya pearls are renowned for their very high and beautiful luster, often called "little light bulbs of the human world." Their luster is strong, capable of sharp reflections and clear imaging. In top-quality comparisons, Akoya's mirror-like luster can surpass that of South Sea pearls. High-quality specimens can reflect a human face. The luster of freshwater cultured pearls is relatively softer, primarily diffuse reflection, appearing silky and gentle. Some high-quality freshwater pearls can achieve good luster, reaching 70%-80% of saltwater pearls. Certain high-grade freshwater pearls can achieve "very 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 typically have minor surface blemishes. The fewer the blemishes, the higher the quality. Perfectly flawless pearls are extremely rare and expensive. Akoya pearls have a higher surface smoothness, with blemishes often appearing as tiny pinpricks. Freshwater pearls may exhibit growth lines such as spiral patterns or indentations on their surface. Surface quality is divided into four grades: Very good (near flawless), Good (minor blemishes), Fair (moderate blemishes), and Poor (numerous blemishes). Blemish level 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. Too thin a nacre layer can affect luster, and wear may lead to loss of luster or even "skin peeling." Akoya pearls have relatively thin nacre compared to other types of saltwater cultured pearls, typically between 0.15mm and 0.55mm. 0.5mm is considered a thick nacre for Akoya. According to GUILD standards, Akoya pearls with a nacre thickness greater than 0.4mm are of better quality. Akoya is most sensitive to nacre thickness. The thinner nacre of Akoya helps in achieving a rounder shape. Freshwater cultured pearls (mainly non-nucleated) typically have a nacre thickness of 0.3 to 0.8mm. The internal structure of non-nucleated freshwater pearls is almost entirely composed of nacre. Prolonged wear of freshwater pearls may gradually lead to a loss of luster due to friction, resulting in a relatively shorter lifespan. Nucleated freshwater cultured pearls (Edison) have thicker nacre, ranging from 0.8-3mm. Overall, saltwater pearls have thicker nacre and a longer lifespan. Saltwater pearls (such as South Sea and Tahitian pearls) typically have nacre ranging from 0.8-3mm. South Sea pearls can have nacre up to 2mm, which is 60 to 100 times that of Akoya. VII. Daily Wear & Suitability Akoya pearls, with their high luster, roundness, and classic white hues, are a very popular choice for everyday wear. They are suitable for versatile necklace designs that exude elegance, sophistication, and classic charm. They are also appropriate 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 uniquely shaped pearls), are a popular choice for daily commutes and casual wear. High-quality freshwater pearls (with very strong luster, near-round shape, and minimal blemishes) are visually indistinguishable from saltwater pearls to the naked eye and offer excellent value, making them ideal for everyday wear. They are suitable for students, new professionals, or lovers of uniquely shaped pearls. If you have a limited budget and primarily wear pearls daily, high-quality freshwater pearls are an excellent option. From a purely functional perspective, there is very little difference in the wearing experience between high-quality freshwater pearls and saltwater pearls.
