How to choose how to choose a diamond to a satisfactory diamond ring
Select the bare drill from the diamond 4C start: size, color, clarity, cut. If you choose a carat below the carat, then the proposed choice of high-color low-clarity, if it is more than a carat, better quality can also add value. In addition, diamond fluorescence should also look at. Ringing, then the general is 18k gold and platinum, the former hard, relatively cheap, the latter is softer, relatively expensive to see the individual like.
The value of diamonds is determined by the 4C, so 4C are very important, from the cost to consider it, we also need to focus on the selection of diamonds, in the case of the size of the first proposed from the cut of this C to consider the degree of cut Directly affect the diamond fire color, all we often say that cutting is the second life of diamonds, followed by the color of this C, the color from the DZ, the more close to the D color, diamonds more transparent, it is recommended to consider the final clarity of this C, VS Level and above as well, because the clarity of the diamond only cause a smaller impact.
Mosaic: the current diamond inlay method about a claw inlay, package Amulette de Cartier Ring Replica inlaid, half-package inlay, folder inlay, nail inlay, different mosaic way to the beauty of diamonds also have different show, the general wedding ring in order to highlight the value of diamonds usually use claws More and more recently more and more new choice of unarmed folder inlaid or semi-package inlay, more suitable for the usual wear, including inlay will have the effect of diamonds, pinning is used for small drill The mosaic. In the study of work or ring style is best to consider the usual wear habits.
Ring size: general K white gold ring size (refers to the Wai) are can be modified, because after marriage or the relationship between children, may become fat or thinner, the original ring becomes too tight or too loose, too tight affect the blood Circulation is not comfortable, too large is easy to lose. If there is no diamond or pattern on the rings of the ring, it is easier to zoom in and out, but there are some models that can not be modified or can not be modified at all because the pattern or circle is broken. Ask the store.
Identification: the domestic jewelry store on the use of gem identification books are different, can be divided into international certificates or general domestic identification of the two opened, the so-called international certificate should be GIA, AGS, HRD, IGI … and so on, other names A similar certificate is in fact similar to a certificate issued by a domestic certificate. It is important to the contents of the identification of the book please explain the details of the store, while most of the jewelry store will be accompanied by a store guarantee, on behalf of this ring is sold by the shop, some stores in the after-sales service will ask to see the guarantee, please And the certificate together with the good custody. So that after-sales service is required to have evidence.
How the diamond is formed
Diamond is formed in volcanic rocks, and mainly produced in kimberlite, another kind of diamond containing the original rock called potassium magnesium lamprophite (lamproite), it is a kind of alkaline magnesite volcanic rocks, mainly by the garnet, volcanic glass Formed, can be pyroxene, olivine and other minerals, the typical origin for the western Australian Argyle (Argyle).
Scientists have studied the diamonds from different diamonds and their native inclusions in the world. The formation of diamonds is generally at a pressure of 4.5-6.0Gpa (equivalent to a depth of 150-200km) and a temperature of 1100-1500 degrees Celsius. Although theoretically, diamonds can be formed in the various periods / stages of the earth’s history, and most of the mines currently mined are mainly formed between 3.3 billion years and 12 to 17 billion years.
Some of the diamonds in South Africa are about 4.5 billion, indicating that these diamonds have begun to crystallize deep in the earth soon after the birth of the earth, and diamonds are the oldest gem in the world.
The formation of diamonds requires a long historical process, which is mainly produced by diamonds on the earth’s ancient stable continental regions. In addition, the extraterrestrial impact on the earth, resulting in an instant high temperature, high pressure, can also form diamonds, such as 1988, the Soviet Academy of Sciences reported in the meteorite found diamonds, but the role of the formation of diamonds is not economic value.
What kind of geological conditions can be formed large particles of diamonds
In the depth of the earth about 150-200 km, pure carbon material in the pressure (4.5-6) × 109Pa, the temperature of 1100-1600 camera under the conditions of crystallization, the formation of natural diamonds. There are only a few places in the deep part of the earth that have www.ourlovestore.com the physical and chemical conditions of diamond formation. In theory, any time can be formed diamonds, as long as the diamond to achieve physical and chemical conditions. From the current mining of the diamond mine, most of the diamonds formed in 3.3 billion years and 12-17 billion years of these two periods.
In addition, the alien impact on the Earth, resulting in high temperature, high pressure can also form diamonds. But this way the formation of diamond particles small, poor quality, can not be used as jewelry gem.
When the earth’s shell to produce tension, solid rock began to move and rupture, then the earthquake, volcanic eruption. When the volcanic lava rises from the depths of the earth to the surface, the deeply formed diamonds are brought to the shallow and surface of the earth. After lava cooling we can find diamonds in the cooled rock. When the diamond is enriched and reaches a certain size, we call the diamond primary ore. Rocks containing diamonds are weathered under natural conditions, and diamonds remain on slopes, rivers, and rivers and are enriched to form deposits, called diamond secondary mines.
Diamonds are formed by geological effects, and geographical distribution, climate conditions are not necessarily linked.
Blue and white diamond: a pure as water-like colorless transparent diamonds, especially with light blue for the best. Such as “Centenary” and so on.
Red diamonds: a pink to bright red transparent diamonds, especially in bright and deep red for rare treasures. Australia is its main source. (In the red diamond grading only one level is Fancy Red, no Fancy Intense, Vivid, Light Red)
Blue Diamond: a sky blue, blue to dark blue transparent diamonds, of which the best for the dark blue. This diamond is different from all other colors of diamonds, it contains boron elements and conductive properties. Because of its particularly rare, it is rare treasures. Such as the world famous “Hope (The Hope)” and so on, South Africa’s Primermo mine is its main source.
Green diamond: a light green to green transparent diamonds, mostly due to deformation of the crystal structure, the color is usually only on the surface of the diamond, green diamonds are not easy to have grassland-like bright colors, of which the value of the most green The The Diamond “The Dresden” is the world’s largest green diamond.
Purple Diamond: A light purple to purple transparent diamonds, three times more expensive than colorless diamonds, especially in purple and purple for the rare treasures, the former Soviet Union is its main source.
A golden transparent diamond is a common variety of colored diamonds. If the color is golden and golden, such as The Tiffany, it is astonishing, and it was estimated in 1983. Has $ 12 million.
How to distinguish the types of diamonds
Orange drill: orange is a mixture of yellow and red, usually dark brown feeling of color, and pure orange in the natural color diamond is rare in rare. October 1977 New York Sotheby’s auction, 5.54ct Fancy Vivid Orange (Pumpkin Diamond) sold for more than 1.3 million US dollars high.
Black Diamond: Black Diamond is usually not as a gem-class diamonds, but the world famous “Black Oloff (The Black Orloff)” is reportedly printed in the Indian temple in the elephant on the diamond, also known as Brahma eyes.
Differentiated diamonds are mainly based on the color, flaws and origin of diamonds.
