Nanyang Golden Pearl mainly grows in Southeast Asian waters. In fact, for Kim Jong-il, especially the highly respected Kim Jong-il, it often grows in the South China Sea of the Philippines. Its mother pearl, Pinctada maxima, grows slowly and produces little. It takes 2-5 years for the golden pearl to mature from transplantation. The limitation of origin and time cost has greatly increased the price of gold pearls.
Things are rare, and the scarcity of Nanyang Zhu Jin, whether it is output, size or color, directly affects its price.
Distinguish between golden beads and real beads:
1, look at the color
The dyed beads are dull in color, and there will be color enrichment where holes and defects are drilled. The color distribution along the crack is easy to observe near the hole. Traces of dyes can be seen in the pearl holes, especially there is an obvious dyeing line at the junction of mother-of-pearl layer and pearl core.
The color of natural pearls is not pure, often accompanied by color. Turn the pearl full, and you can see the slight rainbow-like flash changing constantly.
2. Look at these spots
The density of nacre can't be exactly the same. The same pearl, somewhere, will have a relatively high density, or a relatively low density. Then for dyed pearls, the pigment will precipitate at a relatively low density, forming a stain.
Different from the halo of pearls, the number is more or less. Stains have obvious dividing lines, which may leave obvious pigment deposition in some defective parts. Some dyed beads may not see the stain clearly in natural light, but in strong light, the stain is invisible.
3. Internal structure
Under the reflected light, interference halo often appears under the thin pearl layer on the dyed pearl surface. This phenomenon may be caused by film interference caused by dye infiltration into nacre.
4. Price
The color is thick gold, the shape is good, but the price is very low. Please pay attention to this situation. Because Nanyang gold has a small proportion of beads with good color, good shape and no defects, the price will naturally not be very low.
5. Authority testing
Of course, this is the safest way. If you are not sure whether the purchased beads are dyed, please take them to an authoritative testing institution for testing.
Purchasing methods of Nanyang Zhu Jin:
The selection of Nanyang golden beads is generally based on the size, luster, shape and defects of pearls. The bigger, brighter and rounder the pearl with fewer defects, the higher the price. In the case of limited budget, it is suggested to choose according to the order of luster, size, shape and defect for the following reasons:
1, luster: pearls can enhance a person's temperament and make people more dazzling in the crowd. It is necessary to rely on the luster of pearls. A dull pearl is like a stone, no matter how big it is.
Tips for judging luster: Non-professionals can judge the luster of pearls by observing the reflection of human faces on the pearl skin. In the industry, pearls are generally divided into weak light, medium light, strong light and first-class strong light. When judging, you can take the pearl away from the strong light source to look at people's faces. The gloss level of the pearl can correspond to the phenomena of blurred and invisible faces, visible faces, clear facial features and so on. )
2. Size: The larger the pearl, the higher its value, because the longer the breeding time, the higher the probability that the mother shell is prone to pathological changes or death, and the higher the requirements for its own carrying capacity, so the larger the diameter of the pearl, the scarcer it is, the less the output and the higher the price.
3. Shape: "Pearls are round and smooth" pearls are definitely rarer and more valuable, but the shape of pearls can usually be distinguished at close range, so it should be placed in the third place relatively.
4. Flaws: Almost all pearls are flawed, accounting for less than 3% of the total output. Immaculate refers to pearls that can be used as jewelry by the naked eye, not by magnifying instruments. Defects generally require close observation, and it is not recommended to pay too much attention to defects in the case of limited budget.
