My ring is G750 red gold, please what does D0 10ctd0 28ct mean on the back of my diamond ring

G750 Red Gold is an alloy composed of other metals. This alloy has a ** content of 75%, so it is called red gold and is a common material used to make jewelry.

On your ring, and is the weight of the diamond. Indicates that the weight of the main diamond is carat (10 points) and that the weight of the secondary diamond is carat (28 points).

A carat is a unit of weight for a diamond and is often used to measure the weight of a diamond. One carat is equal to a gram. In the diamond industry, diamonds weighing less than one carat are often expressed in points, where one point is equal to one-tenth of a carat.

Therefore, on your ring, and indicate that the weight of the main diamond and the secondary diamond is 10 and 28 points respectively.

The notations for 18K gold are: G750, AU750

G750 stands for 18K gold.

Red gold should be 18k red (also meaning 18k rose gold) The English word for diamond is diamond,; D is the first abbreviation for diamond;

It is 10 points for the main diamond.

It is a secondary diamond of 28 points, that is, there are 10 main diamonds + 28 secondary diamonds, which means a total of 38 points.

The label on the ring is a formal marking method, indicating that the diamond is heavy carats, but whether the ring is real or not cannot be seen from the logo alone.

For the general public, the most important way to distinguish the real from the fake is to see if there is a corresponding certificate and whether it matches.

1 Inspect the gloss and disperse the colored light.

A well-polished diamond has a more brilliant brilliance than a rough diamond. At the same time, a diamond with a standard cut can better express the uniqueness of its strong dispersed band color, which is manifested as a colorful and pulsating "fire". Compared with imitation diamonds, which have the same unique characteristics of high dispersion band color, the light of the dispersion band color of diamonds is soft, while the light machine of the dispersion band color of imitation diamonds is dazzling.

However, it takes a lot of practice to accurately control the difference in light between the dispersion zone color of diamonds and imitation diamonds.

2 Line Diamond Grading Test.

Because diamond cuts are usually canonical, there is almost no light energy to travel through the process pavilion facets, so when the diamond table is placed face down on a piece of paper with black lines, the black lines on the paper are not visible on it. The same phenomenon can occasionally appear on diamond imitations with a high refractive index, such as artificially made strontium titanate and synthetic rutile, and the black line can not be seen, which is to be paid attention to; But for those imitations with a lower refractive index, a bent black line can be seen.

3 Haqi diamond identification experiment.

If the moisture on the appearance of the sample dissipates quickly and feels fresh, then the sample is declared to be a diamond; Conversely, if the moisture in the appearance of the sample disappears very slowly, it is a declaration that the sample is an imitation of a diamond. This is due to the high thermal conductivity of diamonds. This is also known as the "breathing experiment" or "fog water experiment".

For this experiment, if the sample is small, it should be inspected with a magnifying glass. In addition, because the water vapor evaporation rate is greatly affected by room temperature, this method is not suitable for summer.

4 Perspective effect.

This is a diamond identification method for determining the relative refractive index of clear round diamond-type jewelry, especially for jewelry samples with a refractive index greater than . The method of measurement is to put the table or bottom tip of the sample to be measured down on the paper with handwriting, and look through the sample to see the scale of the legible handwriting, if the scale of the legible handwriting is smaller, it indicates that the refractive index of the sample is larger.

5 Shadow Diagram Diamond Identification.

The shadow diagram method is a method used to identify imitation diamond samples with a refractive index greater than single refraction and cut: [is a canonical round diamond pattern. With the help of diiodomethane solution, the jewelry table is completely submerged in a flat-bottomed vessel containing diiodomethane and with a white color background, and a pen torch or other strong single-colored light source is used to shine the jewelry downwards above the vessel, and the shadow pattern projected by the jewelry on the white scene can be inspected, and the diamond and its imitation can be distinguished by comparing the shadow patterns of different products in the process.

6. Tropic water test.

Wash the sample thoroughly so that it is free of grease, and then place small droplets on the sample surface, and if the water droplets can maintain the appearance of the sample for a long time, then declare that the sample is a diamond; If the droplets disperse quickly, the sample is a counterfeit of a diamond.

Summary. Hello, these represent G750 for 18K gold, with a gold content of 75%.

Represents diamond carats.

What does the label G750 mean on a diamond ring?

Hello, these represent G750 for 18K gold, with a gold content of 75%.Represents diamond carats.

D is the abbreviation of diamond, which means diamond, and the CT at the back is the weight unit "carat", 1 carat = gram = 100 points, that is, the size of the diamond on this ring is cents. Generally, diamonds with less than 20 points belong to melee diamonds, which are mainly decorative and have no value to retain value.

Summary. AU750 is the so-called 18K gold, which is 75% of the **. FY should be an abbreviation for the brand or company.

And both meanings refer to the total amount of diamonds. This refers to the weight of the center stone, which is the weight of the largest diamond in the ring, and the total weight of the side stones, which is the total weight of all diamonds except the largest diamond. Such a diamond ring can be bought for about 1,000 yuan on the Internet.

If you buy it in a shopping mall, it will be much more expensive, and if you buy it in a brand store, if you don't discount it, the label price will be about 8,000 yuan.

What does it mean inside the diamond ring?

AU750 or stove is the so-called 18K gold, which is 75% of the content of **. FY should be an abbreviation for the brand or company. And both meanings refer to the total amount of diamonds.

This refers to the weight of the center stone, which is the weight of the largest diamond in the ring, the total weight of the side stones, and the total weight of the diamonds except the largest diamond. Such a diamond ring can be bought for about 1,000 yuan on the Internet. If you buy it in a shopping mall, it will be much more expensive, and if you buy it in a brand store, if you don't discount it, the label price will be about 8,000 yuan.

Can you tell us more about that?

This is a diamond punch stone ring, the ring is AU750, that is, 18K gold, the capital is the main diamond, that is, 9 points of diamond, the lowercase is the side diamond, that is, 3 points of diamond, if you buy it now, the market price of Qi liquid is about 5000 yuan.
