Will Nanyang Jinzhu fade? Natural golden Nanyang beads may fade a little with the passage of time, but they are basically minimal. If it is a lot of fading, nine times out of ten it is fake, and it is the color dyed by the merchant!
Why did Nanyang Zhu Jin decline?
Nanyang golden beads, whether dyed or natural in color. Wear it for a long time and the luster and color will change! Pearl is a very delicate organic fossil jewelry. Too much human sweat in the natural environment will cause oxidation or some chemical reactions, which will lead to changes in the luster and color of pearls! This phenomenon will also happen on gold and silver ornaments.
But the faded Nanyang Golden Pearl in the picture below is fake, I can see it.
Most of the dyed Nanyang pearls on the market are called Nanyang Golden Pearl because of their golden color. The mellow, pure, huge, natural beauty and dazzling luster of Nanyang Golden Pearl show unparalleled elegance and romance, and it is one of the most popular pearls in the world. Nanyang Golden Pearl generally has a pearl diameter of 9- 16mm, which is mostly champagne color between yellow and white, with a small amount of golden yellow, which is precious. Just as China's yellow symbolizes the supreme imperial power. But at present, most of the colorful gold beads in shopping malls are dyed.
At present, the dyeing methods of dyed pearls in the market are mostly based on the physical principle: infiltration. Infiltration is to use the principle of osmosis to infiltrate dyes into the surface of pearls, so as to achieve the purpose of dyeing.
Generally, the color of Nanyang golden beads is not as strong as that of gold, and the pearl texture of freshwater beads is soft, and the expected effect can be achieved in a few hours or days. The quality of seawater pearls is hard, it takes about 2 months, and the cost will be much higher. However, the nacre of Nanyang pearl is denser, and it must be supplemented by strong light to accelerate the penetration and uniform distribution of dyes. This is the meaning of the terms "laser dyeing", "radiation dyeing" and "baking" that we have heard.
Dyed Nanyang Golden Beads are more beautiful than natural ones. Because the dyed Nanyang gold beads have a metallic fluorescence under the long-term irradiation of strong light, the color has reached golden yellow or deeper, and the appearance looks more beautiful than the natural colored gold beads. In mainland China, Beijing and Shanghai are the main destinations for dyeing gold beads. At the worst time, more than half of Nanyang Golden Beads in Beijing and Shanghai were dyed, so everyone should be careful.
Matters needing attention Therefore, how to distinguish the quality of Nanyang Jinzhu should be divided into four points: roundness, luster, cleanliness and volume. Look at the marked quality grade and shop around. We should choose businesses with real photos and real data descriptions of products to avoid being confused by some exaggerated descriptions, so as to select truly high-quality Nanyang Golden Beads.
