The main types in the price of gold The price of gold in the world there are three main types: market prices, production and the official price. Other kinds of gold prices are derived therefrom. A, the market price Market price includes spot and futures prices. The two prices both contact and there's a difference. Both the price is subject to various factors such as supply and demand and interference, change is big, and the price mechanism is very complicated. In general, the influence factors of spot price and futures price are similar, so the two changes in direction and amplitude are basically consistent. But due to the convergence of market trends, the basis of gold (that is, the difference between the spot price and futures price for gold) can follow the approach of the futures delivery period and constantly decreases, and the delivery period, the futures price and spot price is roughly equal to business. The futures price should be stable, in http://www.ourlovestore.com theory, to reflect the spot price plus specific delivery period of holding costs. As a result, gold futures prices should be higher than the spot price, the forward of the futures price should be higher than the futures price of the recent, basis is negative. But as a result of the key factors of the spot price and futures price is complex, for example: the supply of gold in the near future,, including the size of the annual gold, central Banks selling gold reserves, etc.; Gold market demand, here again including gold actual demand (change in jewelry industry, industrial, etc.), the gold recovery and recycling, etc.; World and the political situation of stability, high and low inflation, interest rates, as well as some emergencies are the main factors influencing the investor psychology, affect the gold price movements; Speculators and utilization of gold price volatility, emergency hype, coupled with various types of hedge funds in the market, manufactured illusion of supply and demand. All this may make gold supply and demand imbalance, the world gold market, the phenomenon of the relationship between spot and futures price distortion, at this time, because gold is in short supply, the cost of holding futures cannot be compensated, even form the basis of the positive cases, lead to spot price is higher than futures prices, futures prices higher than long-dated futures prices recently. With the establishment of the Hong Kong gold market, gold market, gold market all over the world have turned into a continuous whole, trading 24 hours continuously. Due to the role of the above factors, gold prices on world markets often dramatic changes. Only, in the average price for a long time, because of these and speculative factors, is a more objective reflect the market price of gold under the http://www.ourlovestore.com influence of supply and demand was. For example: in the international monetary fund in 1976-1976 of 45 times a gold auction, achieve the average price of $228.56 an ounce, the gold price in the market price is very close to London during the same period the average. Second, the production price Production price is according to the production cost to set up a fixed above the market price of clear and stable prices. At today's exchange rate estimation, gold mining about slightly below the average total cost $260 an ounce (1986, South African gold production cost of about $258 a Troy ounce). In fact, as technology advances, the cost of prospecting, mining, refining, etc have been reduced, gold cost is on the decline. The world gold council statistics show that the present gold in the world each year about 2600 tons, while gold every year demand is greater than the production of 300 tons to 500 tons. But because central Banks since 1996's large-scale gold behavior, the international market prices from the high of $418 an ounce, all the way the downward even dip below $257.60 an ounce, less than a certain period of gold production cost, make each big gold producer suffered huge losses. Third, the official price This is used to the central bank official gold with related activities and use of a price. In the official price, is divided into mortgage prices and billing. All countries in the world, the central bank official total reserves (each country central Banks tend to be the largest holder of gold) in 1998 is about 1998 tons. According to the current production capacity calculation, the equivalent of 13 years of world gold output, and accounts for mining of 24.7% of the total 137400 tons of gold stock, this is to determine an important cause of official gold price. 1, the mortgage price. This is Italian for borrowing from the federal republic of Germany in 1974, with their own gold as Cartier love bracelet replica collateral. On the mortgage price determined in the modern history of jin huang has important significance. On the one hand, in accordance with the international monetary fund per ounce of gold is equal to 35 the regulation of Special Drawing Rights (SDRS), meet again on the other hand holding gold central Banks do not freeze the need of gold. , in fact this price is for gold by the United States not to "monetise" the request, and Europe for gold "monetizing" requires a combination of caution. Borrowing, with gold, gold value according to the market price and give a discount, to a certain extent, gold prices to value, because there are a lot of gold in the mortgage. If the price falls, the issue of interest on a loan is higher than the London interbank offered rate. 2, price of charge to an account. It was in August 1971 after the collapse of the bretton woods system. Due to the powerful attraction to the market price, the market price and the presence of large gap between the official price, because of its official gold reserves pricing for all countries, all raised their own official price of gold, and the result is to determine the accurate officer of official reserves account the price. In operating mainly has three methods: (l) according to different discount standards (at market net price or until a discount of 30%) associated with the market price, according to the different in different period to determine the basis of gold (divided into three months average. At the end of average, etc.). (2) based on the pricing of the purchase price. (3) to official history to determine in some countries, such as the United States in March 1973 set of $42.22 an ounce, some countries according to the international monetary fund (imf) 1969 $35 an ounce. Quasi official price in the world gold trading has become one of the more important the price of gold. The cat's eye - the best gems The cat's eye is a chrysoberyl cat's eye effect. In gem, with the cat's eye effect is a wide variety of gem, such as quartz, scapolite, tourmaline  tourmaline  and apatite, but only in the national standards with replica Cartier love bracelet chrysoberyl cat's eye effect can be directly referred to as the cat's eye, the other is the cat's eye effect of gem is not directly referred to as the cat's eye, want to add the name of the gem in front of the "cat's eye", such as quartz, cat's eye, scapolite cat's eye, tourmaline, cat's eye, and the cat's eye apatite.

Rutile in the refractive index of 2.60-2.90, while the refractive index of a chrysoberyl only 1.745 to 1.755, as chrysoberyl and rutile larger differences in refractive index, reflected in the incoming light the rutile inclusions, concentrated into a light and form the cat's eye. Chrysoberyl more opaque, the red gem filamentous inclusions more intensive, cat's eye effect, the more obvious. On the contrary, chrysoberyl more transparent, cat's eye effect is not obvious. When the cat's eye gems in concentrated light source, such as a torch light, and maintain a certain Angle, gem to light yellow, one side will present milk white while the other half.
