Silver is a precious metal second only to gold, but it is cheaper than gold. The color identification of sterling silver jewelry is also relatively simple. The main methods are:

Color discrimination: high fineness silver is white and shiny, low fineness silver is yellowish or gray and not smooth. Generally speaking, the color of silver copper alloy jewelry is yellowish white, the lower the color, the more yellow; The color of silver-white copper alloy is grayish, the lower the final color is gray or even gray black, such as 800 silver is gray, 700 silver is gray, 500 silver is black gray.

Test toughness: silver toughness is good, the result of high bending is not easy to break. Low finish is not easy to bend but easy to break.

Hardness: the hardness of enough silver is lower than that of gold. It can be carved with nails. If the jewelry is soft but not tough, it may be tin or lead.

Look at the stamp: regular manufacturers of Silver jewelry generally have a stamp, international practice with thousands of fractions plus "S" or "silver" or "silver" words to indicate the silver jewelry and its color. For example, "800S" or "800 silver" are said to be 80% silver jewelry. Silver-inlaid items are referred to as SF (SilverPill). The correct identification of the stamp can identify whether the ornament is silver or not and the color of the silver.

Listen to the rhyme: the sterling silver ornaments fall to the ground sound, no elasticity, there will be a "da da da da" sound. The lower the color, the lower the sound, and the higher and higher the sound will be rhyming; If it is copper, its sound is higher and shrill, the rhyme is short and rapid; If it is lead. If it's made of tin, it's going to make a dull sound. Short and unelastic.

Weight: the density of silver is slightly larger than the general common metal, generally speaking: "aluminum light. Silver is heavy. Copper is neither light nor heavy." So weighing it can make a preliminary judgment on whether it is silver. If the volume of the jewelry is relatively large and the weight is relatively light, it can be preliminarily judged that the jewelry belongs to other metals.
