摘要

尽管今天的全球淡水养殖珍珠市场主要由中国产品主导，但日本淡水珍珠养殖始于1935年。直到1982年，滋贺县的琵琶湖一直向国内外市场供应各种颜色的珍珠。由于水污染和施莱格里三角帆的枯竭，一些珍珠养殖场从1962年开始搬迁到茨城县的Kasumigaura湖。如今，Kasumigaura湖的大型有核养殖珍珠年产量低于40公斤，其中一小部分供应给国际市场。本报告调查了“Kasumiga珍珠”的养殖，并描述了其质量和产量。对从Kasumigaura养殖的三角帆蚌×三角帆蚌杂交软体动物中采集的六种不同颜色的珍珠进行了紫外可见光谱、荧光测试和化学分析。

Cultured Pearls from Lake Kasumigaura: Production and Gemological Characteristics

Although today’s global freshwater cultured pearl market is mostly dominated by Chinese products, Japanese freshwater pearl cultivation started in 1935. Lake Biwa in Shiga Prefecture supplied pearls in a wide variety of colors to the domestic and international markets until 1982. Due to water pollution and the depletion of Hyriopsis schlegelii , some of the pearl farms relocated to Lake Kasumigaura in Ibaraki Prefecture starting in 1962. Today the annual production of large nucleated cultured pearls at Lake Kasumigaura is below 40 kg, a small portion of which are supplied to the international market. This report investigates “Kasumiga pearl” culturing and describes the quality and production volume. UV-visible spectroscopy, fluorescence testing, and chemical analysis were performed on pearls in six different colors collected from the Hyriopsis schlegelii × Hyriopsis cumingii hybrid mollusk farmed at Kasumigaura.
