Variety: The value of seawater pearls is more expensive, because the output is scarce, and the output of freshwater pearls is more, and the relative price is cheaper. Of course, good quality or rare freshwater pearls are not cheap. Among seawater pearls, Tahiti pearl necklaces or Nanyang pearl necklaces are particularly expensive, ranging from thousands of poor quality to tens of thousands of good ones. Akoya Haizhu necklaces are usually thousands, and good ones are 10,000 to 20,000. Freshwater bead necklaces are relatively cheap, hundreds or thousands.
Shape: The rounder the pearl, the more expensive it is, because the output of round pearls is less, and things are rare, and the value of round pearls is the highest, followed by nearly round pearls, ellipses, oblate pearls, steamed buns and steamed buns, which are relatively low, because the output of such shapes is high. For example, the 7-8mm freshwater pearl necklace of steamed bread is generally 1,265,438 +0 strings, while the round freshwater pearl necklace costs 6,700. Those that are not so round are usually three or five hundred.
Size: The bigger the pearl, the less precious it is. Every 0.5- 1 mm difference in diameter will make the price different. More expensive varieties of pearls, such as Nanyang pearls and Tahiti pearls, are slightly different in size and will cost more. Take the round freshwater pearl necklace as an example. Generally, the price of 7-8mm is 600-700, and that of 8-9mm is 1000.
Quality: after considering the above factors, consider the influence of quality on price. Quality mainly depends on gloss and skin defects. Gloss is generally an important factor in judging quality. Pearls with good luster have aura and higher quality value. Then look at the defects. Generally, every pearl necklace has some natural defects, which are hard to avoid. Very few are perfect, and the price is relatively high. The shape is relatively less round because there are more pearls, so there are fewer defects. However, the output of round pearls is very small, and there are basically some defects.
Therefore, the price of a real pearl necklace should be judged by comprehensive factors.
