How to distinguish between pure gold and sterling silver in the easiest way

To distinguish between the real and the fake, you need to look at the silver mark, usually engraved in the ring or on the clasp of the chain. One. The meaning of k, k usually means gold content, 24k contains more than 99% gold, 22k is, 20k is 18k is 50%, and 1k is two.

kf and kp for non-pure gold jewelry f--- for imitation gold, (e.g. 14kf for imitation 14k gold jewelry) p--- for gold-plated, (e.g. 14kp for 14k gold-plated jewelry) three. MA said that the gold jewelry was certified by the State Technical Supervision Department and has been inspected by the department with legal effect. Having such a confirmation is generally genuine.

How do you distinguish a national treasure from pure gold and silver?

Summary. The identification methods of sterling silver are:1

Magnetic identification: Sterling silver is a non-ferromagnetic metal that can be identified using magnet testing. 2.

Transparency identification: They can be compared with a translucency meter, and sterling silver has a higher light transmittance. 3.

Resistance test: Their resistivity can be measured using a resistance meter, and the resistivity of sterling silver is lower than that of other metals. 4.

Chemical tests: Some chemical reagents such as sodium hydroxide (NaOH), basic barium sulfate (BASO4), etc., can also be used to identify sterling silver.

Can you add, I don't quite understand it.

5.Observation surface: The surface of sterling silver has a bright silver-white color, no stains and rust, and has the characteristics of bright color.

6.Touch it with your hands: sterling silver has a soft texture and will leave marks as long as you press it, while alloy has a hard and slippery texture and will not leave marks when pressed.

7.Silver test: take a small piece of product, put it in the medicine furnace, add a small amount of silver yellow, ignite, if there is a faint silver-white smoke rising, it means that it is real silver; If the smoke is gray in color, it is not sterling silver.

8.Acidity test: take out the product, dip it in 10% sulfuric acid solution, if there is a powdery substance precipitated out, it means that it is real silver; If there is no precipitation, it is an alloy.

Summary. Hello, I'm glad to answer for you, there are three ways to identify sterling silver: 1. Listen to the sound, the sound of real sterling silver falling to the ground is dull and has no rhyme, and the false sound is crisp and pleasant; 2. Weighing the weight, the real sterling silver has a certain sense of weight, and the fake feel is lighter; 3. Drop nitric acid, the part of the real sterling silver that drops nitric acid on the surface is beige or light green, and the fake one is dark green or black.

Identification method of sterling silver.

Hello, I'm glad to answer for you, there are three ways to identify sterling silver: 1. Listen to the sound, the sound of real sterling silver falling to the ground is dull and has no rhyme, and the false sound is crisp and pleasant; 2. Weighing the weight, the real sterling silver has a certain sense of weight, and the fake feel is lighter; 3. Drop nitric acid, the part of the real sterling silver that drops nitric acid on the surface is beige or light green, and the fake one is dark green or black.

The following methods can also be identified: 1. Look at the mark: Generally, there will be 990 marks on 999 sterling silver, and 925 marks on standard silver. 2. The heavier the weight of the silver, the purer the texture, and there is no obvious feeling of falling when held in the hand, which is easy to be bent, but it is difficult to break.

3. Acidic test silver will change color when it encounters acid, and concentrated hydrochloric acid will be dropped on it, and oxidation reaction will occur, and silver chloride will precipitate. 4. Look at the color of silver is generally slightly yellow silver-white, and the color is too bright or too dull, which is a sign of poor quality. 5. The experimental silver of the magnet will not be adsorbed, and the one that can be attracted by the magnet is not pure silver or doped with some other substances.

1. Acid test: silver will change color or even dissolve when encountering any acid. If a drop of concentrated hydrochloric acid is placed on the inside of the silver jewelry, a white moss-like silver chloride precipitate is immediately formed. This is not the case with other ***.

2. Sound rhyme: The sound of standard silver jewelry is dull after landing, no bounce, no rolling.

3. Look at the color:

When you get a piece of sterling silver jewelry, your first instinct should be to look at the color. Sterling silver jewelry is mostly a silvery-white color with a slight yellowish tinge. The higher the purity of sterling silver jewelry, the whiter it appears. And the surface is delicate and evenly shiny.

2. Listen to the voice:

Listening to sounds, it's a way to identify a lot of things. Some things are true if they have a crisp sound, some things are true if they are dull, some are true if they are loud, and some are true if they are small. When standard sterling silver jewelry hits the ground, the sound is muffled, unlike something that bounces up and doesn't roll.

If your sterling silver jewelry doesn't react to the above and is something else, then you have to doubt its authenticity.

1. Color identification method: Observe with your eyes, look white, shiny, fine workmanship, and print the store number on the jewelry, which is silver jewelry with high fineness; Poor color, poor color and luster, and dull are mostly fake silver jewelry.

2. Bending method: fold silver jewelry lightly by hand, easy to bend and not easy to break; stiff, barely folded with lower fineness; After bending or cracking with a hammer, it will crack for silver-clad jewelry; Those that can't stand light folding, and are easy to break, are fakes.

3. Throwing method: throw the silver jewelry on the table from top to bottom, and the silver jewelry with high color and low bounce and stable sound is high; Thrown on the table and jumping higher, loud, fake or low-quality silver jewelry.

4. Nitric acid identification method: use a glass rod to drop nitric acid on the file of silver jewelry, which is brown beige and slightly green. It is dark green and has a low color of black. 5. Look at the color (also known as looking at the noodle file) test:

The higher the purity, the whiter the silver, the delicate and uniform shiny dough, and the polish. If it contains lead, the dough is tidal with a blue-gray tinge; If it contains copper, the dough file is rough and rotten, and there is a feeling of dryness. Although the oxidized ** has "black rust" on the surface, its color is black and bright, while lead, tin, and white copper have no luster, and their color is twilight.

5. Weight: **The density is slightly larger than that of common metals, generally speaking: "aluminum is light, silver is heavy, and copper is not light and heavy."

Therefore, the weight can be preliminarily judged whether it is **. If the jewelry is large and lightweight, it can be preliminarily judged that the jewelry is other metals.

Summary. There are three identification methods here: silver punch mark method, water drop method, and magnetic pressure method.

Identification method of sterling silver.

There are three identification methods here: silver punch mark method, water drop method, and magnetic pressure method.

You've done a great job! Can you elaborate on that?

1. Silver punching method: Overlap the image of sterling silver with the image of half silver, and then gently hit it with a hammer, the image of sterling silver is easy to produce punch marks of different shades of silver with round and thin colors, and the image of half silver is prone to dents. Second, the water drop method:

Use a sterling silver dropper to drop a few drops of chlorinated water on the silver image in front of you, if the droplets from the dropper are easily integrated into it, and there are no signs of heat or corrosion, it can be concluded that most of it is pure silver. 3. Magnetic pressure method: put the silver image on the table or other non-magnetic objects, and then use a magnetic object to press slightly, at this time, the sterling silver image will not have any traces of heating and electric spark in addition to easy deformation and discoloration, while half silver is not.

The identification methods of sterling silver include listening to the sound, weighing the weight, dropping nitric acid, distinguishing the color, bending method, etc.

1. Listen to sounds.

When the sterling silver is dropped to the ground, the real sterling silver will make a crisp and pleasant sound, and the sound of the fake sterling silver falling to the ground will be slightly crisp and pleasant.

2. Pad weight.

Silver is a very precious metal, its specific gravity is greater than the same color iron, lead, tin and other metals, so the real sterling silver peeling liquid has a certain sense of weight in the hand, while the fake sterling silver feels relatively light.

3. Drop nitric acid.

After dipping nitric acid with a glass rod and dripping it on the surface of sterling silver, the part of the real burning sterling silver that drops nitric acid will be beige or pale green, while the part of the fake sterling silver dripping nitric acid will be black or dark green.

4. Distinguish colors.

If you look at it with your eyes, it looks white, shiny, and finely workmanlike, and the store number is printed on the jewelry, which is silver jewelry of high fineness; Poor color, poor color and luster, and dull are mostly fake silver jewelry.

5. Bending method.

Fold silver jewelry lightly by hand, easy to bend and not easy to break; stiff, barely folded with lower fineness; After bending or cracking with a hammer, it will crack for silver-clad jewelry; Those that can't stand light folding, and are easy to break, are fakes.
