1, diamond ring brand
It is necessary to choose the brand of diamond ring, and both quality and after-sales are undoubtedly more secure.
2, diamond ring style
Different people like different styles of diamond rings.
Sharp diamond style: a unique sense of "sharp edge" power
The diamond cut in the shape of olive tip drops belongs to the category of pointed diamond. These cutting processes determine that the number of carats of this kind of diamond must not be less, otherwise it will be more difficult to set and produce results. The unique diamond tip has a "sharp" appearance and feeling. Therefore, the diamond-pointed ring is especially suitable for mature women to bring their mature charm to the extreme. For women who are too weak, this style may not be the best choice, and there will be a feeling that they can't suppress their aura.
Unified drilling ring: low-key and versatile.
Perhaps not everyone likes "pigeon eggs", therefore, the lowest-key diamond ring refers to the style that has always existed for them and is enduring for a long time. This kind of ring is not dominated by any diamond, but emphasizes the balance of small diamonds. The whole ring is decorated with starlight diamonds, which is bright but inconspicuous. Daily wear will not appear abrupt, and it can also be matched with other diamond ornaments when dressing up. Can be described as an all-round master.
Six-claw round drill: sense of stability, most suitable for enjoying diamond fire.
Six-claw diamond ring, in design, the round diamond is embedded in the platinum ring, which sets off the diamond to the maximum extent and makes its light refract in all directions with the cutting face, showing its brilliance.
Four-claw round drill: flexible, suitable for a variety of mosaic combinations.
The four-claw round drill inherits the basic style of the six-claw round drill, but at the same time it is not as "full of stars" as the six-claw round drill, and accordingly it is more lively and agile. Because the four-claw inlay does not emphasize the existence of the ring claw like the six-claw inlay, sometimes the size of the ring claw is even deliberately reduced to as small as possible, which not only makes the diamond look lighter, but also can be combined with more small diamonds in different inlay ways.
Square diamond: the best way to show the texture of diamond table top.
Square diamond wedding ring means fashion, luxury, personality and enough shock. Whether it's a princess square diamond or an emerald square diamond, it attracts people's attention with its absolutely wide diamond table.
3. 4C parameters of diamond
4C- Color:
Diamonds are equivalent to prisms. It can divide the light into colored lights and form colored flashes after reflection. Just as we wear colored glasses, the color of diamonds will act as a filter. Thereby reducing the escape of reflected light. The lighter the diamond color, the stronger the flash color. The higher the color level.
The colors of diamonds are divided into two series. Common colorless series include colorless transparent, nearly colorless and light yellow. There are also color series including dark yellow, gray, pink, black and so on. The color classification of diamonds is based on the color classification established by GIA, Gemological Institute of America, from "D" (transparent and colorless, starting from the initial letter of diamonds) to "Z" (yellow). Colored diamond is a kind of rare and extremely expensive diamond. The color grading system is not suitable for colored diamonds. The colors of D, E and F, also called transparent and colorless, are extremely precious and rare, and the difference between them depends on experts' careful identification. The more common color is G to J, which is also called near colorless. It is easy for experts to distinguish, but it is difficult for ordinary people to distinguish, and it is even more difficult to detect if it is embedded in jewelry; The color below k, also called light yellow, may be recognized by ordinary people, but the price is obviously much cheaper.
4C- Clarity:
The clarity of diamonds is determined by professionals according to the content of diamonds under the magnifying glass of 10 times. The clarity of a diamond is the number of defects. Defects that affect the clarity of diamonds are generally divided into two parts, namely internal defects and surface defects. According to the visibility, type, quantity and distribution of defects, the clarity of diamonds can be divided into several grades.
Every diamond contains natural inclusions, just like natural birthmarks. The quantity, size, shape and color of these inclusions determine the purity and uniqueness of diamonds. It must be seen under a magnifying glass of 10 times.
Cleanliness is a grading system for measuring the number of inclusions and defects: from FL/IF (no internal defects/defects) to I (defects).
4C- Cutting:
Diamond cutting-its roundness, depth, width and uniformity of cutting surface all determine the brightness of diamond. Many gemologists believe that the cutting and grinding process of a diamond is the most important diamond characteristic. Because even if a diamond has perfect color and clarity, poor cutting and polishing will make a diamond lose its dazzling brilliance.
Cutting is a grading system to measure cutting and grinding technology: from ideal cutting to poor cutting.
Ideal cut: represents the standard that only 3% of first-class high-quality diamonds can reach. This cutting makes the diamond reflect almost all the light that enters the diamond. Elegant and excellent cutting.
Very good cut: represents about 15% of the diamond cut. It can make diamonds reflect the light of standard grade cutting, but the price is slightly lower.
Good cutting: represents about 25% of diamond cutting. It is the diamond that reflects most of the light entering the drill bit. Much cheaper than VG.
General cutting: It means that diamonds with a roughness of 35% are still high-quality diamonds, but the light reflected by general cutting diamonds is not as good as that of G-cut diamonds.
Differential cutting: This includes all diamonds that do not meet the general cutting standards. These diamonds are cut deep and narrow or shallow and wide, which is convenient for light to escape from the edge or bottom. When the cutting is too shallow, the light escapes from the bottom and the brightness of the diamond is damaged. If the cut is too deep, the light will easily escape from the pavilion, and the brightness of the diamond will be damaged, tarnished and dim.
The cutting ratio of diamond, especially the ratio of pavilion depth to table width, determines the intensity of light reflected and refracted by diamond, which determines the fire color of diamond.
