Silver jewellery generally with the English abbreviation of silver (” S “or” Sterling “). The mark of Standard Silver is S925. The silver mark is S990. But many countries do not make a mark on silver jewellery.
2 . See the color
The higher the purity of silver jewelry, the more white the silver, and the surface looks evenly shiny and polished. If lead is present, the jewelry will appear bluish-gray; If it contains copper, the surface of the jewelry will appear rough, and the color will not be moist.
3. Weigh by weight
Silver has a slightly higher density than standard metals, about 10.5g/cm. The weight of aluminum is light, the importance of silver is heavy, and the weight of copper is neither fair nor plump. Therefore, weighing the purchased jewelry can make a preliminary judgment on whether it is silver. Suppose the jewelry volume is large and the weight is light. In that case, we can preliminarily judge that the jewelry is another metal.
4. The acid test.
Silver will change colour in contact with any acid and even dissolve. If a drop of concentrated hydrochloric acid dropped on the inside of the silver jewellery, a white mossy silver chloride precipitate would appear immediately. Other precious metals do not have this phenomenon.
5.Judge the hardness
Silver hardness is lower than copper and than lead; tin can use to pin jewelry to inconspicuous places to test, such as needle slip; the surface is challenging to leave traces and can be determined as copper jewelry; If it is made of lead or tin, the trails are obvious, and it can be preliminarily defined as silver jewelry.
6.Listen to the sound
Sterling silver jewelry is vital, not elastic. The lower the color, the lower the sound, and the higher the sound with rhythm; If it is copper jewelry, its sound is more elevated and shrill, rhyme sound is short and rapid; If it is lead or tin jewelry, the sound will be dull, sharp and unelastic.
7.Heating
Heat the silver accessories at a high temperature until they are almost melted, then stop cooling and put them in water. So if it’s not silver, you can see what it’s made of, and if it’s silver, you can figure out the color.
8.Bending method
Fold silver jewellery by hand; it is easy to bend and not easy to break. Stiff, forced folding of low colour; After bending or a few knocks with a hammer will crack for silver-covered jewellery; Can not withstand light folding, and easy to break for the fake.
9.See the fracture
Cut off the silver jewelry and look at the fracture color. If the fracture is white and cotton, the surface of the jewelry is smooth and delicate. After oxidation, the surface color is black and bright, and it can be concluded that its completion color is about 98%. If the fracture is rough and soft, slightly red, the result is about 95%; Fracture is white and gray, somewhat red color is about 90%; Hand bending is complex; if the fracture is light red or gray, its color is about 80%; About 70% of the finished color of silver, it’s surface white yellow and dry, if thefracture slightly red, yellow, complex bending; If the fracture with black, yellow with black, its color has been below 60%. However, this identification method is related to silver-producing silver, requires a certain amount of eye and experience, requires careful examination, and needs to be more accurate.
