Sapphire forensics

It is understood that at the end of April this year, Prince William of England was married, and the wedding ring of Princess Wang was the sapphire ring left by Diana's Princess Wang. This set off a wave of sapphire's popularity in the global jewelry market. Even the merchants selling sapphire in the Guangzhou market have become more and more, in which the price of high-quality sapphire of 2 carats or more has risen by 30%.

More than 2 carats have long-term appreciation space Since the spring of this year, influenced by international fashion trends, major domestic jewelry brands have also competed to attract sapphire business. When the reporter visited the Tianhe City and its surrounding shopping malls, it discovered that among the ten jewellery merchants selling sapphire jewelry, there were four or five. And one year ago, sapphire was still hard to come by.

However, the reporter found that since sapphire is still not a mainstream jewellery such as jadeite and diamonds, businessmen are worried about the backlog of funds. Most of the products sold directly on the counter are low-end and medium-end products. Most products with a price of less than 2 carats are sold at high prices. Between a few thousand and 30,000 yuan.

According to Xiang Xiankai of Guangdi Jewelry, under normal circumstances, only sapphires weighing more than 2 carats and having excellent color and low brightness have space for long-term appreciation. Collectible grade sapphires can weigh up to 3 carats. the above. Otherwise, the sapphire whose size is too small, from the visual effect point of view, it is not clear whether it is blue or black and is not suitable for collection.

For this reason, major merchants in Guangzhou have come up with a compromise solution. If customers have needs, they can entrust the merchants to order a large volume of sapphire. It usually takes two weeks to one month from the time you fill in the order documents and arrive at the payment.

Market Analysis: Sapphire is still in the midst of price depression. The price of sapphire on the Chinese mainland market also shows a polarization trend. The prices of low-grade sapphires, which are dark blue and blue, show a downward trend. Compared with two years ago, prices dropped by two to three percent. The sapphire, with a brighter color and a weight of 2 carats or more, has risen about 30% this year from the same period last year. The three-carat, sapphire in the middle of the color, now sells for 120,000 to 130,000 yuan in the Guangzhou market.

Compared with diamonds, the price of sapphire this year is significantly slower than the former. Taking a two-carat product as an example, the price of a 2-carat white-yellow diamond does not exceed 500,000 yuan, and the price of a 2-carat-class sapphire sapphire is about 60,000 yuan. And this year, high-quality diamond crazy prices, 2 carat white diamond prices have risen to over 1 million yuan, 2 carat sapphire's price but 80,000 yuan up and down, sapphire is still in the price of depression. In the current mainland market, there are some sapphire sapphires, mostly yellow sapphire, and the main component is all three aluminas, but it appears unusual yellow due to the presence of other metal elements in the mineral growth. Some merchants sell for high prices in the name of rare sapphires. However, in fact, these gemstones contain many impurities and their color is not pure. The collection value cannot be compared with blue sapphire. In the international market, only pink sapphire can be sold at a higher price. Dior and Cartier brands have all launched pink sapphire jewellery products.

A magnifier can be used to identify sapphire cracks and visit the market in Guangzhou. The reporter also found that similar to diamonds, the common sapphire in the market is small in size, so it is not easy to identify it. The most secure method is to send it to a professional identification agency for identification. However, according to Zhang Shibai, who has been relied on by Golden Diamond, we can also use the magnifying glass to make the most basic identification.

Shape characteristics: color unevenness First of all, the color is not uniform is the sapphire's largest appearance characteristics, with a magnifying glass to see the depth of the different growth patterns, common blind double crystal pattern, cracks are also many. If the color is uniform and there is no crack, it is definitely not sapphire. Furthermore, the sapphire crystals are not uniformly crystallized. When exposed to sunlight, they can see the ribbons that flow with the light. If there are no ribbons or ribbons that lack dynamic movement in the sunlight, they are not really sapphires. .

In addition, the world’s best sapphire, like jadeite, is still produced in Burma. Because of the titanium-containing color, it is bright blue, containing ruthenium-like rutile and fingerprint-like liquid inclusions. This kind of sapphire is very rare in the Guangzhou market and happens by chance. The price is also above 100,000 yuan. The sapphires that appeared in the Guangzhou market were locally produced in Australia, Thailand, and China. They contained more iron, which was caused by iron and was dark in color. The sapphires were basically blue-black or dark blue. If the market encounters 50,000 sapphire transactions and bright colors of sapphire, most of them are not genuine.
