What does the diamond ring look at the size?

Diamond weight is calculated in carat (also known as card). 1 carat = 200 mg = 0.2 grams.
is divided into one hundred copies, each of which is called one point. 0.75 carats are also called 75 points, and 0.02 carats are 2 points. Under other conditions, as the diamond weight increases, the value of the value is increased in geometric level;
diamonds with the same weight will be far from the difference in color, clarity, and cutting. In each different size and shape, you can find a high -quality diamond. The most important thing is to find a diamond that is suitable and style that makes you like.
1, clarity
The clarity of diamonds usually uses 10 times large mirror to classify the inside of the diamond, surface flaw, and its degree of impact on glorious It is divided into 10 levels of LC, VVS1, VVS2, VS1, VS2, SI1, SI2, P1, P2, P3.
This diamonds are divided into excellent, good, good, and good, generally 5 levels. P -level diamonds are also called Class I diamonds. The following P -level diamonds are generally not used as gems, so they are generally only divided into P1/P2/P3.
2, color
has many natural colors, from precious colorless (white after cutting), rare light blue, pink to common slightly yellow. The more transparent, the more white can penetrate, and the more colorful after refraction and color.
The diamond color grading is in the hierarchical environment of a professional laboratory. The technicians will be determined repeatedly with the standard color of the standard color than the standard color stones.
The whitening diamonds are set as D -episodes (that is, start with Diamond's first letter). The color of diamonds is divided into 11 levels, in turn: D, E, F, G, H, I, J, K, L, M, N.
3, cutting
The cutting of the diamond refers to the accuracy of its cutting ratio and the perfectness of the decoration. Good cuts should be as good as possible to reflect the brightness and fire of diamonds as possible, and try to maintain the weight of the rough. GIA's cutting level from high to low is divided into ID (standard), EX (excellent), VG (good) G (good) G (good),
The national inspection is divided into: EX (excellent), VG (very good (very good) (very good) ), G (good). The best cutting is the "eight hearts and eight arrows". It uses the world's top Cupid -style cutting, which is CEMNI's exclusive and original diamond cut. The perfect and symmetrical eight hearts and eight arrows are stunning.
So in China, ordinary people generally look at the size of the diamond. It is actually unscientific. Because China is more popular. Therefore, the more popular concept is high -quality glory diamonds. High -quality glory diamonds generally grasp the three principles of 4C: clarity, color (color), and cut (CUT), and the three standards must meet certain standards at the same time.
This terminal sales (diamond ring) price of a diamond is usually 3 to 4 times that of the factory price of the finished product, that is, the increase rate of the circulation field is as high as 200%to 300%, and some well -known brands cost 400%~ 500%, even higher.
The expansion data
The origin of the weight of diamond -Clark's history:
, a small and precious diamond, which requires a very subtle and consistent weight unit. Most of the early jewelers used plant seeds with equivalent volume and consistent weight as a unit of scale.
The earliest adopted by the wheat ears and rice beans carobseed. The ears of wheat are a kind of grain, and their weights are neat and consistent. The pearls, Jinquiders, thermal balancing and medicament measurement methods adopted today are derived from wheat ears.
, the beans of rice or spiny locust, the beans that are concluded are still important poultry, domestic animal feed and spice raw materials. The merchant used this bean as a unit of scale, and today's public campaign is derived from it.
three, the weight of carat was only standardized in the early 20th century.

It is loose but not tight. There is a suitable enclosure. Then make a mark at the intersection, remove the thin rope, and measure the length with a ruler. Measure a few more times, calculate the average value, and the thin rope must choose without elasticity. Or measure it with the ring that is wearing, find yourself to wear the most comfortable ring, and then draw this round four -class segmentation point, measure the diameter with a ruler, and find the suitable one according to the ring inch control table.

The size of the ring is particularly comfortable for the ring to wear. When buying a diamond ring, couples should pay attention to accurately measure the size of the ring.

If it is measured by yourself, you can prepare a note or a rope, a pen, and a ruler. Two laps of the thickest positions that need to be measured around the rope or note, and tighten it; then use a pen to sign in the same position of the two ropes in the two laps, remove the rope and spread it. The length, this length is the length of the finger root.
What should I pay attention to when measured the size of the ring
1. Pay attention to the measurement of the measuring inch: the length of the fingers due to the inflation and contraction of the finger, the perimeter in different environments will be different. It is measured when it is too cold in the morning or later or when it is too hot at noon. At this time, the measured ring size measured may not be accurate. In winter, you can choose a slightly larger ring size; in summer, you can choose a slightly smaller ring size.
