How to choose a diamond ring

How to choose a wedding diamond ring

Selecting principles

The "4 C" principles of diamonds: cutting (CUT), color, purity, and carat Carat Weight). This is the focus of identifying the quality and value of diamonds.

The cutting

cutting is the only human factor. A skilled diamond cutter can make a good diamond ore dazzling, and he can reflect the internal light to the surface. The cutter wants to cut it as if left and right as if in the mirror.

The good diamond ore may be deserted by the lack of technology of the cutter. An ideal diamond should be round and 58 clear cutting edges, which can reflect light to the greatest extent. A high -quality diamond has high value, strong reflexivity and symmetrical, but its cutting is not perfect. Cutting inferior diamonds may not be cut too deep or too shallow because it is to keep its maximum weight, so it cannot make it shine. Polishing technology will also affect the quality of diamonds. A perfect cutting, symmetrical diamonds may reduce value due to poor polishing.

r

It will display some diamonds used for comparison in some large jewelry shops. Because ordinary customers cannot distinguish the color of diamonds with the naked eye. The color of the diamond is based on colorlessness, and gradually follows the yellow.

The purity

In general, the value of diamonds determined by flaws. More accurate, it depends on how much impurities in the drilling ore. Almost every drilling ore contains impurities, even with good quality drilling ore.

carat

Carat was once considered a decisive standard for measuring the value of diamonds. When someone said that 2 carat diamonds were bought, people would feel incredible. In fact, the cutting, color and purity and weight of diamonds are equally important for diamond value. A 2 -carat diamond with a poor cutting process, yellowish color, and defective 2 carats is much lower than a perfect cutting, transparent and pure diamond. Therefore, the weight of diamonds is not the main factor that determines the value of diamonds. The weight of diamonds still affect its value. It is important to find out whether the weight of the diamond that the jewelry dealer tells you. Therefore, you can measure the weight of the diamond on the spot when you buy it. If the jewelry dealer is unwilling to do this, then go to other shops.

is inlaid

is also an important part. If it is not inlaid, it will cause a lot of trouble, and it may cause the diamond to fall off. Therefore, when buying a diamond ring, be sure to check whether the bracket is firm and whether it is thick enough with the diamond.

r

The more and more styles in the market now, jewelry designers are constantly innovating. But the more classic styles are round, oval, pearl -shaped and square. The shape of diamonds does not affect value and quality. Instead, it also reflects the original shape of the diamond before cutting.

The written description

. Your diamond should have a proof of authenticity, which shows the quality, weight, and cutting technology of the diamond. This is the guarantee for the diamond ring you buy.

The recommendation:

.6.1 Pick diamonds should try to choose more than 0.20 carats, because only diamonds with more than 0.20 carats can begin to show the "fire color" of diamonds, Because the diamonds below 0.20 carats are too small, the optical effect of diamonds appeared is not obvious, and it can hardly be seen. If you have the ability, it is best to buy diamonds over 25 points, and more than 25 points of diamonds "Firecai" starts to appear obvious.

. Avoid integer bits, such as 0.30, 0.50, etc. When buying, think about it for 0.0 carato for so much money. However, you are unlikely to find such stones such as X8 and X9, because as long as the processor modifies the cutting angle slightly and changes within the standard range, you can cut the polar standards to cut the X8 and X9 stones with the stones of the X8 and X9 points. Processing into a 30 -point diamond with a standard cut, so choose the digital insurance of X7.

The diamond grading certificate guidance

.6. 1 Purchasing diamonds must be equipped with a class certificate

6. I can say responsiblely that China's grading standards are stricter than foreign grades, especially the clarity and color grading. Beijing's national prosecutors and heads of the country can sometimes reduce 1-2 large-level international certificates. For example, a client brought the GIA certificates to 50 points, VVS1, F-colors, and VeryGood cutting diamonds. After the XXX gem testing center in Beijing was graded, 50 points, VS2, H-i color, and verygood were cut.

. 6.1 Certificate of grading:

1) Bare diamond grading certificate

2) finished grading certificate

2 certificates Although they are all graded certificates, the difference is large

1) Weight

6.1 Diamonds with naked diamonds can be used to call accurate weight

. The finished product grading can only estimate the weight based on the size of the diamond countertop (because it has been inlaid, the weight is gold diamonds, so it cannot be weighed), but it is estimated that it is inaccurate after all ( Affected by cutting, the estimated premise is the cutting pole standard). If it is a 98 -point stone, the classification is 1 carat after inlaid. It may be more than 5,000 yuan

2) Cleaning

6.1 naked diamond grading is a gradient that can observe diamonds from different angles, improve the diamond The opportunity to see all small bags

. Diamonds with finished product grades have been inlaid on the precepts. The grades can only observe from the table, and may not observe all the bags. And the body, sometimes the diamond bodies are just blocked by the metal inlaid with diamonds, and it is not seen at all. A diamond with a feathers (crack) SI -level SI may be promoted to VS or even VVS level

3) Color

.6.1 The classification of the classmate of the cricket of the naked diamonds observes diamonds from the table and the bottom tip, placed on the diamond -color card for grading, and generally the color stone (diamonds (diamonds (diamonds (diamonds (diamonds As long as the color is observed by the bottom)

.1 finished diamond -grade diamonds have been inlaid on the precepts, and can only be observed by the countertop, and the gold around the diamond will affect the gradientist Judgment (insufficient whiteness of gold, resulting in a decrease in yellow tone of diamonds), the finished grading is based on the experience of the grades

4) 1 The tiester of the naked diamond grading observes diamonds from all directions, and sometimes uses the cutting proportion instrument for cutting. The accuracy rate is high

6. On the top of the precepts, it can only be observed by the table, and the gold around the diamond will affect the judgment of the gradient, and it cannot be accurately cut off. At the same time, it can be seen that the above 4C grades above the 4C grades can be seen. The grading standards are much easier than the naked diamond grading standards, and the grading of the finished diamond is not very accurate. Most of them depends on the experience of the gradient.

. Therefore, the same diamonds, naked diamond grading is Si1, H-i, 28 points, Good cut

finished product grading may be VS1 (VVS2), g (f), g (f) , 30 points, VeryGood cut

Suggestions:

6.1 First, do not blindly pursue international certificates. The domestic grading standards are stricter than internationally.

. Second, try to choose a naked diamond grading certificate. If you have to choose a finished product class certificate, please understand that the level of your diamond and the diamond -grading diamonds of naked diamonds are the same. The actual level is generally lower than the actual level of naked diamond diamond diamonds. (That is to say, the actual value of the finished tiered diamonds is generally lower than the actual value of the same level of naked diamond diamond diamonds)

common diamond maintenance methods are as follows:

1 , Wash the cleaning solution

This with a small bowl or tea cup to make warm water, and adjust the appropriate amount of neutral cleaner in the water. Immerse the diamond in the water, brush it gently with a toothbrush, and then use a net sieve to rinse with warm water under the faucet. Finally, wipe it with a soft cotton puffy cloth.

2, cold water immersion

In a small bowl or tea cup, immerse the diamond in the water for about 30 minutes, and then use a small brush to brush it gently on the front and back of the diamond. Wave in the water for a while, and take it out with a paper towel.

3, fast cleaning method

purchased a bottle of brand -name jewelry cleaning solution, together with the container, washed the diamond according to the instructions.

4, there are some secrets here to help you care for diamonds.

Is when you are doing housework, please do not let diamond jewelry stick to chlorine -containing bleach. Although it does not damage the diamond, it will fade or change color.

5, do not wear diamonds when washing or rough. Although the diamond is hard, it may be scratched if the texture direction is hit.

6. Send your diamond jewelry to the jewelry dealer once a year to check whether the inlay is loose and worn, and fix it and brighten it again.
