What ring is printed with S925 and d0.01ct? Is it direct?

Classification of gold

1. [Full gold] and [thousands of full gold]

the national standard has very clear provisions on the fineness of gold content in gold products, that is, each gold jewelry sold by merchants must be marked with its gold content and weight. The gold content of not less than 99% is called full gold, which is deep Huang color, commonly known as two 9s. If the gold content is not less than 999, it is called thousand gold, which is the highest value in the naming of jewelry fineness. The mark is thousand gold, 999 gold, gold999 or g999. The marks of gold jewelry include manufacturer code, material and purity, such as: X gold 990, xau990, X full gold, etc.

2. [platinum]

strictly speaking, platinum has nothing to do with gold. Platinum is an extremely rare metal, white, hard in texture, never fade, and has permanent value preservation. It is generally matched with diamonds. Also known as platinum symbol: according to PT national regulations, only jewelry with platinum content of 85% or above can be called platinum jewelry and must bear the PT mark. Platinum jewelry usually has purity marks of pt850, PT900, pt950, pt990 or pt999 (thousands of platinum). 850 represents 85% purity, and so on

3. [3D hard gold]

3D hard gold or hard gold refers to the improvement of pure gold in the process of processing through process improvement (through the improvement of gold content, pH value, working temperature, organic brightener content and stirring speed in the electroforming solution, the hardness and wear resistance of gold are greatly improved), so that it has high hardness, good color of finished products and is easy to be polished into various shapes, It overcomes the disadvantage of insufficient hardness of pure gold. It will be more expensive because of the complex processing technology. However, hard gold jewelry can not be repaired if there are cracks, flaws, gaps and falling pieces. The most fatal point is that hard gold cannot be recycled (the vast majority of the actual inquiries do not recycle hard gold)

4. [K gold], [white K gold]

[K gold] is a sign of gold jewelry with different gold content. The gold content of 1K is about 4.166%, so the gold content of 24K, 22K, 20K and 18K is 99.99% (pure gold), 91.65%, 83.32% and 74.98% respectively. The rest can be obtained by multiplying 4.166% by K number. [white gold] white gold is not gold but platinum. Its main component is gold, which is white after adding other metals

5. [gold plating]

I won't say much about gold plating. A layer of gold is sprayed on the metal surface

6. [color gold]

color gold is also called color gold. It is melted by adding a variety of color metals to the gold. The price will become more expensive with the rarity and uniqueness of the color (it can be understood that the process is complex and expensive). It is different from hard gold. It can be recycled.

cleaning and maintenance of gold.

1. Keep the luster of gold jewelry. Apply a thin layer of nail polish on the gold jewelry

2. Avoid wearing gold jewelry when doing heavy work, especially rings

3. When swimming, take off the gold jewelry to avoid chemical changes on the surface after touching the seawater or pool water

4. Gold jewelry must be kept away from chemicals. (my "pan" fun)

5. After wearing, the gold jewelry often loses its luster due to the infection of dirt and dust. At this time, just put the gold jewelry in a neutral detergent, soak it in warm water and clean it, then take it out and wipe it dry

6. Do not touch pure gold jewelry with high volatile substances such as perfume and hair gel, or it will easily cause the gold jewelry to fade

7. If the gold ring and the platinum ring are worn on the same hand, it is easy to cause the two to rub against each other, making the surface of the gold ring partially rub against the platinum and turn white. As for the white gold jewelry, it can be polished with an agate knife or rubbed with rough cloth (such as canvas) to restore the brightness of the gold

8. If there is a black silver film on the surface, use 2G of salt, 7g of baking soda, 8g of bleaching powder and 60ml of water to prepare a "gold cleaner". Put the gold jewelry in a bowl and pour the cleaner. After 2 hours, take out the gold jewelry, rinse it with water (preferably not hard water), bury it in wood chips and dry it, and then wipe it with a soft cloth

9. The luster can also be restored by wiping with toothpaste or hot concentrated rice soup

10. The easiest and convenient way to clean gold jewelry is to use soap and soft brush with gentle nature

11. Frequently worn gold jewelry should be cleaned and inspected once a month.

D0.01ct refers to a 1-minute diamond (0.01 carat) inlaid. If it is custom-made, it is about 50 yuan. If it is not custom-made, add 20 yuan. A diamond with a score of 1 is 100 good and 20 bad. This ring is basically below 200, which is more cost-effective. It also depends on the brand. If it is a big brand, it will cost several hundred yuan. If it is not a brand, it will be worth more than 100 yuan.
