Gao Yan value opal to prevent "facelift" fraud
In October, the peak season of jewellery consumption came as expected. In the urban retail market and the auction market, Opal Jewelry once again received attention. At the October auction of a large jewelry auction house in Dongfeng Road, Guangzhou, 7 pieces of Opal products were auctioned by more than a dozen collectors and all were sold.
At present, Opal is in the stage of starting and rising in the Chinese market. Recently, a reporter from the Guangzhou Daily visited the Australian main production area in Australia and found that Chinese collectors still have misunderstandings about opal.
Comparing the common diamonds and jadeites, Opal is not only high in value but also full of features: it has the visual effect of “live color†that follows the changing sun, and the light waves overflow and the pearls are precious. Moreover, at present, the Chinese market is at a stage of initial and rising, and the price is relatively low.
Guangzhou Daily reporter visited the major opal production area in Australia and found that Chinese collectors still have misunderstandings about opal: black opal is not black opal, opal “live color†comes from sunlight diffraction rather than internal color; The value of the parking texture and cutting work is worthy of the attention of collectors.
Origin market PK Guangdong market: Australia market price is 35%~50% cheaper
During the autumn season, the reporter visited the opal market in Melbourne and Sydney, Australia. 95% of the world's opals are produced in Australia, and the retail market price is indeed cheaper than the Guangdong Province, which is the global jewelry production and sales base.
In the brand-name jewelry store operated by the Chinese in the rocky district of Sydney's downtown area, the black opal semi-finished product weighing 6.2 carats is equivalent to RMB 32,100, while in Shuibei Jewelry City in Shenzhen, China (the number of opels in the commercial area is large), similar The price of the product is between 50,000 and 60,000 yuan.
For white opals that are not so high-end, the price of 8.8-carat semi-finished products is only about 9,800 yuan, but in Shenzhen, China, the price of the same products is around 18,000 yuan. Considering that Shenzhen Shuibei Jewelry City is a wholesale-oriented, retail-oriented shopping mall, the price is relatively cheap. In the Australian domestic market, the price of opal is at least 35% to 50% cheaper than the opal in the Chinese market.
At the same time, Australia is also a major diamond producing region, and its diamond price in the retail market is generally 50% cheaper than the price of diamonds in the Chinese retail market.
The Guangzhou Daily reporter learned that there are many opal collectors among the local residents of Australia. Most of Opal's auctions at Christie's and Sotheby's in Hong Kong are directly obtained from private jewellery lovers in Australia.
Tan Lian, chairman of the Guangdong Fair Auctions, told the Guangzhou Daily reporter that unlike the “good†(like big size) preferences of collectors in mainland China, local Australians value the quality and cut of opal, and the texture is good. Black Opal, which is low in color saturation, is the most sought-after variety; and similar to diamonds, the opal is exquisitely cut and completely preserves the natural characteristics of Opal, which is favored by everyone.
At the same time, the Guangzhou Daily reporter also found in the Australian market that Australian residents are more affirmative of the “monochrome†opal than the mainland Chinese residents, and the opal stone with insignificant characteristics such as dark blue and royal blue is not good. Less, you can sell a higher price than the typical "live color" opal (that is, the multi-color flicker change on the surface of the gem).
In China's Shenzhen Shuibei Jewelry City and Guangzhou Kangwang Road Jewelry Street, only the "live color" opal is the best seller. The people who know the monochrome opal are not many, and everyone is worried about fakes. In Australia, the well-known crystal opal, animal and plant fossil opal, is even more traded in China.
Opal stone
A main producing area in Australia with "color change" characteristics of inorganic gemstones, most opal stones show fluorescence multi-diffraction effect under sunlight, Moss hardness is 5~6, the English name means "all gemstones are brilliance One body."
It was discovered by Europeans in Australia in 1840 and was highly sought after by collectors. It is one of the emerging categories in the international jewelry market.
Three misunderstandings:
Opal "live color" comes from external diffracted light and does not fade
Compared with the Australian market, Opal is still in its infancy in the Chinese jewelry market. Both consumers and collectors often have misunderstandings:
Myth #1: Many people often think that the black opal often said to be black opal. In fact, black opal is the dark opal of the embryo body, not the whole gem is black, but mostly dark blue, sea blue, royal blue, deep purple as the background color, accompanied by various patterns of colorful changes. Black Opal is produced in Leiden Ninrich, New South Wales, Australia. It is the most famous and expensive opal variety, and is highly sought after in terms of color and gems.
Myth 2: The colorful changes of Opal are transmitted from the inside, so the glare will make the Opal fade. In fact,
Opal's colorful changes are caused by the diffraction of natural light, which diffracts white light to present color, so sunlight does not fade the opal. This can be used as one of the methods to identify true and false opal. Only the "live color" that is rich in the sun is the true opal, and the opal, which has little change in the color angle of the conversion angle, is probably a fake opal.
Misunderstanding 3: Some domestic merchants believe that immersing the opal in the water after the glycerin and toothpaste rub will make the opal regain its brilliance. But in fact, the effect is not great. The hardness of Opal is actually not high. Moss hardness is only 5~6, which is half of the diamond. For this reason, Opal is a gem that is relatively easy to be scratched and damaged. After many years of use, it needs to be re-polished to make it heavy. Now brilliance, ordinary wiping, soaking effect is not big.
Identification and collection suggestions: "pin method" can be identified
Guangzhou Daily reporter consulted Guangdi Jewelry and Guangdong Gold and Silver Jewelry Testing Center and found that as a new imported opal, the phenomenon of fraud has appeared. The main reason is the low-level fraud method of “splicingâ€. The surface of the gemstone is true opal, mud iron. The bottom of the mine is made of two layers of stone, which sells high prices together; or the three-layered stone made of glass topping, opal for interlayer and mud iron ore, which is deceptive.
Director Xiang Xianyi of Guangdi Jewelry recommended the identification method: the magnifying glass looks at the side of the gemstone. If the joint seam can be seen, it must be a splicing product. Bubbles can also be seen on the joint surface of similar products; carefully use the tip of the needle to test the tip. Poke into the seam, the true opal density is high, the hardness is too high, it is impossible to insert the needle.
For the collection of Opal, domestic jewellery collectors have a different opinion. The more consistent views are: colorful opals with obvious color changes, large flashes and even lines, which are still the main products of the market.
Among them, Lin Zhaohui of Guangdong Huayou Auction House compares the Chinese and foreign auction market data and believes that the color category in black opal has been steadily rising from 2010 to now, with strong value-added potential, currently in international The transaction price in the market has reached more than 30,000 yuan / carat, which is not comparable to the ordinary opal of 3,000 to 12,000 yuan / carat.
In addition, Chairman Hong Hanfeng of Guangdong Zhongchuang Jewelry Design Center believes that the collection standards of Australian local residents are more rational and objective, and the processing value of Opal cannot be underestimated; the same opal raw materials are only perfect in shape, well polished, and symmetrical and smooth. It can reflect the changing color of Opal to the greatest extent, which is similar to the law of the diamond market.
