Silver is available in countless forms recently. Keeping up to date on the various types of silver can help you make informed choices about your purchase. In the details below, you can find information on the different types of silver used in the manufacture of gems around the world.
First, it is important to understand that silver is alloyed with other metals or elements during the manufacture of jewelry. There are various reasons for producing different alloys of silver, but these are discussed in the following details.
Second, the quality of the silver can be confirmed through a quality stamp that looks like a finished product. Some companies have dul to fraudulent markings, but these are rare cases. A magnifying glass is required to observe these marks. Also remember that you only need to stamp the gem if there is enough space. Therefore, small jewels may continue to be unengraved, even if they are of good quality.
The following details allow you to gather information on various standards for quality stamps related to silver jewels.
1. Good [.999]
This is the purest form of silver and consists of 99.9% silver. The remaining 0.1% contains traces of other elements. Fine silver is soft. The color is gray. Has a dull appearance. Its luster is known to be more like glass than polished sterling silver items. In addition, scratches and dents are likely to occur. Therefore, they are not commonly used on jewelry because they don't wear properly.
However, using silver has several advantages. Metal can be cast easily. Fuse without soldering. Does not change color easily.
As a result of its soft texture, use in necklaces and earrings is more popular than bracelets and rings that are frequently pulled. Silver clay products are forged into fine silver. They caused an increase in demand for silver jewelry in the United States. Fine silver gems have .999 FS or just 999 stamps. And the silver hill varieties are .999 quality.
2. Sterling [.925]
In the United States and other countries, sterling is the standard quality of jewelry. Sterling silver jewelry contains 92.5% silver. Other metals such as nickel and copper make up the remaining 7.5%.
It is important to add other metals to the alloy to harden the metal, increase durability, and shine the gem-everything is a bid to attract clients.
Most of them are familiar with the silver shade of sterling silver. Although it looks glossy, it is easy to discolor. Sterling silver gemstones must be polished regularly to keep the gemstones clean and long-term.
Comparing the hardness of sterling silver and fine silver, you can see that the former is harder. However, sterling silver is softer than many other metals.
Sterling silver gemstones have a .925 stamp.
3. Unprocessable alloy
Recently, alloys with no discoloration have been introduced. Among many brands, Argentium manufactures these alloys. They are usually composed of 92.5% silver, but some branded items have a high silver content. The remaining alloys are manufactured using metals such as copper and germanium.
Germanium has the ability to harden the alloy and make it resistant to discoloration. However, non-discolored alloys will discolor for a certain period under severe conditions. The good news is that it requires less maintenance than sterling silver. Resistance to discoloration is the main advantage of these metals.
However, it is also worth noting that the metal Argentium does not require soldering for forging. However, there are drawbacks associated with Argentium. This metal is expensive and not easily available compared to sterling silver. Also, the metal has a .925 stamp, so it cannot be distinguished from sterling silver. Jewel producers must also apply to obtain the authority to stamp an Argentine mark on their work. In addition, stamps are large and cannot be used for jewelry.
4.Coin
Coin silver has been a commonly available alloy in the United States in the past. Today, people are confused with their names and are rarely found.
& # 39; Coin Silver & # 39; indicates that the silver content is 90% silver. The remaining 10% is made of copper. Coins are not made of this metal. Rather, it was produced from scrap coins from previous times.
Some countries' money coins do not contain silver, but are composed of other inexpensive metal types. Collectable or investment items contain a large amount of silver. It is marked with a relevant mark and a valid certificate is attached. Coin Silver Jewel is engraved with a .900 seal. Most of these items are antique.
5.Silver
There is a question about jewelry that is advertised as the only "silver". We recommend that you purchase gems that are clearly defined with respect to the quality standards you comply with. Without these markings, the quality of the silver alloy is not high. Jewelery companies typically stamp gems when space is available or tag the finished product with quality tags.
6. Silver filling
The term silver filled is the term used to re-layer gemstones when the percentage of silver increases throughout the recession. Because the metal content of the piece is not uniform, it is not an alloy. Nevertheless, its surface contains sterling silver.
Items filled with silver contain 5-10% sterling silver and are welded to a brass base. This metal has not been standardized in the US due to its new release. Cannot cast because it is hierarchical. Compared to silver plating, the silver layer is thicker. However, the quality is not higher than many silver alloys. In addition, it will change color. They are soldered by precision instruments and trained professionals. It's not commonly seen in the market these days because of the lower price of silver. There are still no stamp quality standards set for these materials.
7. Silver plating
Silver-plated gems consist of a thin silver layer on top and are used in costume jewelry. They contain only a small amount of silver. They are preferred by some people because they are affordable. Nevertheless, they change color quickly. Only the manufacturer's logo is attached, not the quality mark.
8.Nickel
Name & # 39; Silver & # 39; Nickel Silver & # 39; Silver only, not for metal. These are alloys mainly composed of copper. Other metals such as zinc and nickel are also included. Nickel silver is soft, inexpensive and resembles sterling. These alloys can be soldered, but the seams are visible.
Nickel silver is also known as German or Alpaca silver. Costume jewelry is made of these alloys. Some people think it should be defined as a nickel alloy because some people suffer from allergies when exposed to nickel.
9. Tribe
Tribal or Tibetan alloys are also silvery. Pure silver is not included, and the alloy content varies. Some varieties also contain toxic metals such as lead that may endanger our lives. It is therefore recommended to be unstable when choosing these alloys. But they can improve your appearance and should be chosen for the design and not worth the money.
10. Mexico, Thailand, Bali
Countries such as Mexico, Thailand and Bali produce large amounts of silver. However, you must verify the quality stamp before purchasing. It is also known for producing low quality alloys. The country name does not guarantee the quality of the item.
Silver quality test
The amount of silver in the alloy can be determined by performing two tests.
When it comes to X-ray testing, non-destructive, expensive equipment is required and should be performed in the laboratory. The result is moderate accuracy. Due to the metal layer and plating, accurate results cannot be obtained.
Assay testing is recognized as the best way to learn about the silver content of alloys. It is destructive and 0.5 grams of metal must be melted to determine the alloy ratio. The test is accurate when a skilled worker performs in the laboratory.
Neither of these tests serves as a good option for customers who want to test at home. It is advisable to always approach honest and well-known dealers when declaring the materials used in jewelry. Quality seals are also useful for learning about incorporated metals and elements.
