Well, for lack of experience of the ordinary Tibetan family, how to distinguish sapphires, blue diamonds and blue fluorite do?
PK Market Price: Sapphire Blue Diamond steady upward increase
Widely in jewelry, general manager of Mr. Hou Shunyu presented blue sapphires and diamonds are not value-free city of mainland China's demand has proven year by year growth trend.
Sapphire is basically gradual positive development over the years, from 2000 to 2006 time period, prices rose 120%, after 2007, despite the financial crisis, but little price change. Blue diamond prices appear after the first wave and then fall line flat, with 2008 as the watershed in the previous five-year period, the price rises more than 2 times, while basically the same as in 2008, at the end of 2008, a diamond carat weight blue top has a large volume fell 35%, the small size of the blue diamond prices by at least 15%.
In the market of Guangzhou, general point of view, a price of 5,000 carats sapphire yuan more than 2 million the price of a one carat blue diamond is more than 50,000 yuan from top to bottom, while the weight the prices of a one carat diamond white as high as RMB 70.000 ~ 100.000. On the contrary, is known as semi-precious blue stones especially parts fluorspar prices to calculate the period of almost a year in Guangzhou City, prices of blue fluorite massive drop of almost a double.
Rating PK: Levels of Blue Diamond or less
Diamond Blue and white, like, weight, cut, color and clarity are key indicators to measure its value. However, showed a pale blue diamond sea blue levels, or less, to measure the color of blue diamonds, the current row in the consensus of opinion. It is generally believed that the gem table control of the spectrum, white and blue in color between the "is light blue" is considered the most valuable blue diamonds. In addition, impurities less bright gray better the more expensive price of the product.
Compared to Blue Diamond, Sapphire's value even more difficult to measure because that the system of international pricing, ruby and sapphire have been much less in the specifications of the diamond. However, sapphire and blue colors will call "it" contains precious little melanin as possible, sapphire blue sea, in general, more worth the money, because the former is more beautiful color. In addition, the sapphire is also a corresponding weight clarity, cut and targets, with fewer impurities, which better reflects the value of the most expensive sapphire.
With sapphire, blue diamonds, compared with blue fluorite is not a problem, the value of a variety of colors is quite close to each other not much difference between value. Clarity is a measure of blue fluorite most important criteria, cracks, impurities, as well as blue fluorite largely determine the price sale. The weight of blue fluorite in direct proportion to its price is not developed, but an exponential decay, a size of 5 × 5 × 5 cm in the market price blue fluorite over 200 to 400 per hour, but if you Carved in size from size 10 × 10 × 10 cm, although the big eight times the size of price but also to reach a maximum of 1,000 yuan.
