How to distinguish the materials of jewelry?
The material of jewelry can be divided into alloy, stainless steel, acrylic, rhinestone, 925 silver and other major types
There are many types of alloys, such as copper alloy, lead-tin alloy, zinc alloy, etc., in terms of their material texture and composition.
At present, lead-tin alloys are mainly used in the market. The superior properties of lead-tin alloy materials, such as good toughness, strong plasticity, and low melting point, and low material prices have brought a strong foundation for the popularization of the popular jewelry industry.
The nature of alloys is not classified as a "precious metal" because it cannot resist acid and corrosion. Once worn, it will turn black or rust when exposed to acidic solutions such as sweat, perfume and hot springs. However, alloys The cost is lower, so it is generally used in popular styles.
What is an alloy? Simply put, it is composed of two kinds of metals or non-metals. Substances with inherent metallic properties are "alloys". Some alloys also have great changes in chemical properties. All in all, it is a mixture, or synthetic metal, containing various components such as zinc, iron, silver, etc. The higher the tin content, the better the alloy quality. In addition, the reason why some people have allergic symptoms when wearing alloy jewelry is caused by the "nickel" in the alloy. (But because nickel can make the product smoother, more shiny, and low cost.)
2). Stainless steel
Stainless steel jewelry is a very special kind of metal jewelry. The texture is very tough, but it is also very corrosion resistant. It will not turn black like silver, and it will not be allergic to jewelry like copper, and it will not be like alloy jewelry because Lead is poisonous, and stainless steel jewelry always maintains its own color tone for life at room temperature.
The stainless steel jewelry is made of the same material from the inside to the outside, and has passed the artificial sweat test. Its characteristics are completely non-corrosive, and resistant to strong acids and alkalis, without discoloration, no fading, no allergies, no deformation, hard and bright.
It is a green high-grade environmental protection jewelry that will not produce any side effects and harmless to the human body. However, the price of stainless steel is relatively expensive compared to alloys.
Acrylic is a new type of material that has emerged in recent years. Its appearance is like jade, and its patterns, patterns, and colors are not restricted by alloy jewelry. It has become another popular fashion for hair accessories.
Rhinestones are often favored because their appearance and effect are very similar to those of diamonds. At present, the rhinestones on the market are mainly named and distinguished by the place of origin.
The first choice is Australian rhinestones, which are superior in quality and craftsmanship, but the price is relatively high. Next is the Czech rhinestones; the Guomao rhinestones are correspondingly poor, and their brightness refraction is not ideal enough, but the price is relatively cheap, which is lower in the market.
In addition, there is a more high-end diamond-like material than rhinestones, zircon, which has a high degree of imitation, and is often used to make some high-end sterling silver and gold-like jewelry. Other cheaper materials are acrylic rhinestones, turquoise and other materials.
Weighing silver with a silver content of not less than 925 per thousand. Also known as "925 silver", pattern silver is usually made by mixing 92.5% silver with 7.5% copper.
Because of the incorporation of copper, the polished luster of its finished products is dazzling and beautiful than pure silver, so it is often used as a jewelry material and silverware. This is the commonly used raw material for silver jewellery on the market.
In order to increase the gloss of 925 silver jewelry and reduce its oxidation degree, some manufacturers will also plate a layer of platinum on it (note that it is platinum instead of platinum). Such products are commonly known as real gold and silver products in the industry.
