The longer the pearl is, the longer the value is, the higher the value is.

The relationship between size and value is very close, but the longer the value is, the longer the value is. The higher the value is, the higher the value of this year's Hong Kong International Jewellery and Jewelry Fair, the four pearl auctions organized by the Japanese team has become a hot spot for attention, with 64 gold pearl necklaces to 210,000. High-priced transactions in the US dollar and products with transaction prices ranging from 50,000 to 150,000 US dollars abound. Coincidentally, the jewelry collection of the late Hollywood star Elizabeth Taylor was recently put up for auction, including the “Wanderer Pearl”, the wedding gift given by the Spanish prince to the Queen of England’s Tudor Mary, estimated at US$200,000.

However, due to the advancement of jewellery processing technology and the popularity of color pearls in the fashion industry, the number of dyed pearls is increasing, and collectors need special attention when buying.

Judging from the current auction of pearl auctions, the price of colored pearls tends to be stronger, and the average price has risen by 20% to 30%. Golden and dark gray pearls have become the most sought-after varieties.

According to Guangxian's Xiangxian Xiang, according to color, pearls are generally white, gold, and black, and golden pearls are difficult to bred, and natural near-extinction is the rarest, so the value is the highest.

Gold is prolific in the Philippines, Indonesia, etc. White is produced in Japan, Nanyang, and China. Black is prolific in Tahiti, which also includes dark gray pearls.

But no matter what kind of pearl, to achieve the collection level, its diameter must be more than 8 mm.

China’s old saying “seven-pointed beads, eight-point treasures” says that a pearl with a diameter of eight millimeters is a “treasure”. It can be seen that the relationship between the size and value of pearls is extremely close. The bigger the more precious.

The size of most black pearls is between 9mm and 10mm, and about 60% of the black pearls do not exceed 11mm in size.

Therefore, generally 11mm is the limit of the treasures of the black pearl, and the fine round black pearl of 15mm or more is very rare and is the most worthy product.

However, since pearls are organic in the final analysis, the longest lifespan is generally not more than 50 years. The longer the age of the pearl, the higher the value.

Tian Pengfei of the Guangdong Provincial Gold Association believes that for freshwater cultured pearls with long-lasting durability, the best collection period is 10 to 20 years, while for Haizhu, the best collection period is only 8 to 15 years; black pearls, golden yellow pearls The collection period is 2 to 5 years longer than white pearls.

Reminder: Pearls have more birthmarks on the surface of birthmarks. The softer the collection, the higher the value of collection. After 1995, a large number of pearls were cultured in mainland China, which drastically reduced the overall price of the world's pearls. For this reason, the phenomenon of pearl fraud has become increasingly scarce. . We now identify pearls. We should mainly select from the texture and find treasures that are suitable for collection.

The Chinese mainland has also begun to cultivate large-scale pearls on a large scale, and some new varieties have been produced. Color-made jewellery is also eye-catching and its collection value is not high. One is a pale gray freshwater pearl that is a variation of white pearls. The difference from Tahitian black pearls is the lack of melanin and the color is not uniform. The other type is dyed pearls. The number has increased sharply at this jewellery exhibition. It is to dye large-grained white pearls into golden or black. The difference from Tahitian pearls is that the colors are too uniform and placed in sunlight. Under irradiation, there is no faint halo.

According to the reporter’s understanding of the Chinese mainland market, the above two kinds of pearls account for 6 to 7 percent of all color pearl products, and investors need special attention.

Whether it is artificial breeding or not, the pearl with thicker bead has a more collectible value. Falling pearls on the ground, the height of bounce and ground height difference of 2 to 10 cm is generally a thick layer of pearl beads.

Furthermore, the two beads can be worn against each other. If pearl powder is produced and there is no worn core, it is a pearl of higher quality.

In the end, there are almost no pearls without flaws, and each pearl has a different birthmark. The more natural the birthmark and the softer the surface glow, the higher the collection value.
