rhodium jewelry set suppliers Tips for buying pearls (phần 2)

Đăng trên qua Kingjy

Kích cỡ: The size of a pearl is measured based on the diameter and width of the pearl, usually in centimeters. The larger the pearl, the rarer, the higher the price. Different types of pearls have different sizes. South Sea beads are larger than Japanese beads and freshwater beads. The common size is between 11 Và 18 cm. Although there are South Sea beads over 20 cm, they are not many and the price is high; Japanese beads Beads from 6 cm to 8 cm are more common, while Japanese beads over 8.5 cm are more expensive.

Shape: From a market perspective, the rounder pearls are more expensive. The reason is that cultured pearls are biological phenomena and cannot be controlled by humans. Perfectly round pearls account for only about 5% of the total output. The higher the asking price in the market. But now other shapes of pearls are gradually being favored by consumers, and their value is becoming more and more attractive.

Ánh sáng: The surface luster of a pearl is related to the thickness of the nacre. If the nacre is solid and thick enough, the surface luster is sharp and bright. On the whole, South Sea pearls generally have better luster, and high-quality pearls have a shiny surface like a mirror. To achieve mirror-like luster, the thickness of the bead layer must be at least 1 cm. To evaluate the luster, you can use the light spot of the lamp tube reflected on the surface of the pearl to observe. Tất nhiên rồi, the light spot is sharp and even the lamp tube is clearly visible, tất nhiên rồi, the luster is very good!

Flaws: The flawless high-end pearls are of course the best, but the price is relatively high. The truly flawless pearls are hard to come by. When selecting pearls, it is not necessary to be overly perfect for the natural flaws of the pearls, because minor flaws are inevitable. The important thing is to achieve the most beautiful state after making jewelry.
