一文看懂海水珠和淡水珍珠的區別
產地不同
海水珍珠主要產自日本近海、法屬波西尼亞大溪地群島、澳洲和印度尼西亞海域。例：日本Akoya、日本馬貝珠、大溪地黑珍珠、南洋白珠、南洋金珠。 淡水珠主要產自中國長江中下游的湖南、浙江一帶的江水和湖泊裡。例：愛迪生珠
產量不同 海水珍珠產量很低，一個珠蚌只產一顆珍珠，養殖過程極為艱辛，時間長、成本高，因此價格比較昂貴。
淡水珍珠產量相比較要高很多，一個珠蚌能產多顆珍珠成本相對較低。隨著養殖技術逐漸成熟，產量也大。中國淡水珍珠的年產量佔全球95%以上。
形狀不同 海水珠是插核養殖，就是將一顆正圓的核插到母貝里成長完結的，所以形狀一般呈比較規則的正圓形。無核培育的淡水珍珠，是經過植入細胞膜來培養的，所以其產出的珍珠多為不規則形狀，正圓的份額較少。雖然淡水珍珠的產量很高，但達到正圓無暇強光的佔比不到千分之一。
顏色不同 海水珠的色彩主要以白色系、金色系、黑色系、銀色系等為主，在有暈彩的前提下更顯顏色層次豐富。淡水珠的主要顏色為白色、橘粉色、紫粉色等。
光澤不同整體光澤順序為：日本akoya>南洋珍珠> 淡水珍珠
市場價值不同 受成珠率以及養殖環境的影響，海水珍珠要珍貴些。大家在選擇珍珠時，主要從珍珠的光澤、大小、形狀瑕疵等方面判斷珍珠的品質，海水珠從這幾方面來看普遍優於淡水珠。但認定淡水珍珠一定比海水珍珠差的說法也是比較片面的，好的淡水珍珠也同樣珍貴。
淡水珍珠冒充海水珍珠？
有些不法商家聲稱自己賣的是海水珍珠，其實是以淡水珠冒充海水珠，如果遇到品質高、價格便宜，而且不帶權威證書的，便要多加注意了！幅照染色：用淡水珠染色去冒充海水珠，一般金色/黑色/深色的珍珠容易做假。例如：南洋金珠/大溪地黑珍珠/真多麻
這種做假珍珠表皮比較厚，皮光毛糙顏色死板，摸上去沒有天然珍珠的順滑感。另外可以透過肉眼觀察珠孔，如果裡面是黑色的，那就是幅照珠了！
如何避雷？ 挑選信譽良好的商家盡量挑選有信譽，並設有實體店舖的商家，能夠親身到店挑選現貨為佳。購買帶權威證書的產品市面上出現愈來愈多新的證書機構，為珍珠進行鑑定，但有些並沒有很高的認受性。以珍珠鑑定來說，較有權威性的只有兩家日本證書機構-真珠科學研究所及真珠綜合研究所，兩者都擁有較長的歷史和行內較高的認受性。 The Differences Between Saltwater Pearls and Freshwater Pearls Different origins: Saltwater pearls are mainly produced in the coastal waters of Japan, the Tahitian Islands of French Polynesia, Australia, and the seas of Indonesia. Examples: Japanese Akoya, Japanese Mabe pearls, Tahitian black pearls, South Sea white pearls, South Sea gold pearls. Freshwater pearls are mainly produced in the rivers and lakes of Hunan and Zhejiang along the middle and lower reaches of the Yangtze River in China. Example: Edison pearls. Different yields: Saltwater pearls have a very low yield. One pearl oyster produces only one pearl. The cultivation process is extremely arduous, time-consuming, and costly, so the price is relatively expensive. Freshwater pearls have a much higher yield by comparison. One pearl oyster can produce multiple pearls, so the cost is relatively lower. As cultivation technology has gradually matured, the yield has also become large. China's annual freshwater pearl output accounts for more than 95% of the global total. Different shapes: Saltwater pearls are cultivated by bead nucleation, which means a perfectly round nucleus is inserted into the mother oyster to grow and complete formation, so the shape is generally relatively regular and perfectly round. Non-nucleated freshwater pearls are cultivated by implanting mantle tissue, so the pearls produced are mostly irregular in shape, with a smaller proportion being perfectly round. Although freshwater pearls have a very high yield, those reaching perfectly round, flawless, and strong luster account for less than one-thousandth. Different colors: Differences between saltwater pearls and freshwater pearls: The colors of saltwater pearls are mainly white series, gold series, black series, silver series, etc., and with overtone, the color layers appear even richer. The main colors of freshwater pearls are white, orange-pink, purple-pink, etc. Different luster: Differences between saltwater pearls and freshwater pearls: The overall luster order is: Japanese Akoya > South Sea pearls > freshwater pearls. Different market value: Influenced by the pearl formation rate and cultivation environment, saltwater pearls are more precious. When choosing pearls, everyone mainly judges pearl quality from aspects such as luster, size, shape, and flaws. From these aspects, saltwater pearls are generally superior to freshwater pearls. However, the claim that freshwater pearls are definitely inferior to saltwater pearls is also rather one-sided. Good freshwater pearls are likewise precious. Some unscrupulous merchants claim they are selling saltwater pearls, but actually pass off freshwater pearls as saltwater pearls. If you encounter ones with high quality, low price, and no authoritative certificate, you should pay extra attention! Irradiation and dyeing: Freshwater pearls are dyed to pass them off as saltwater pearls. Generally, gold/black/dark-colored pearls are easily faked. For example: South Sea gold pearls / Tahitian black pearls / Madama. Freshwater pearls passed off as saltwater pearls: This kind of fake pearl has a relatively thick surface, rough skin luster, and rigid color. It does not feel as smooth as natural pearls when touched. In addition, you can observe the pearl hole with the naked eye. If the inside is black, then it is an irradiated pearl! How to avoid pitfalls? Try to choose reputable merchants with physical stores, and it is best to be able to visit the store in person to select from stock. Buy products with authoritative certificates: More and more new certification institutions are appearing on the market to appraise pearls, but some do not have very high recognition. For pearl appraisal, only two Japanese certificate institutions are relatively authoritative—the Pearl Science Laboratory and the Pearl institute . Both have a long history and relatively high recognition in the industry.
