项链 - 14K包金 黄金 珍珠

Akoya珍珠，搭配金质扣环，是绝对的珠宝经典，体现了传统的日式品质。Akoya珍珠在Pinctada fucata（Akoya牡蛎）壳内培育，主要在日本。这种珍珠是全球最早实现人工养殖的珍珠，归功于Kokichi Mikimoto。下面是对你这条项链的特征、价值与属性的详细分析。Key Features and Value of Akoya Pearls:
Mirror Luster (Lustre): 盐水 Akoya珍珠因其极其深邃、明亮、几乎金属般的光泽而比淡水珍珠更受青睐。它能完美地反射光线，使珠粒看起来仿佛从内部发光。Perfect Roundness: 在所有珠类中，Akoya珍珠拥有最高比例的完美圆珠。这是因为在牡蛎内部植入了一个圆形的母珠，外壳随后小心地以天然珠母薄层覆裹。Assembly technique: The thread is assembled "through a knot." This is an important marker of premium jewelry. Knots prevent the beads from rubbing against each other and damaging the mother-of-pearl, and if the thread breaks, you won't lose all the pearls. Clasp (Filigree Box): A gold box clasp decorated with a central pearl is an iconic design of the mid-20th century (c. 1950-1980). Japanese export pearls of that period were most often equipped with clasps made of 14-karat gold (585 fineness).
