Techniques to Distinguish Real 925 Ksj Markings from Fakes

Real 925 Ksj markings, also known as sterling silver marks, are unique to a particular piece of silver jewelry. The 925 stands for 92.5%, which is the percentage of pure silver content in an alloyed sample. Ksj is a trademark registered to Joergcheng Jewellery Co Ltd, a company based in Wuxi City, China. Generally, only those pieces of jewelry that pass very strict quality control standards and come with required quality certificates will be stamped with the Ksj mark.

To ensure that your jewelry is marked with a genuine 925 Ksj marking:

1. Check the back of the piece carefully for signs of filing or sanding – fake markings may have been added with these techniques.

2. Ask to see official certificate papers that establish where and when each item was made, and what materials it is made from; such papers should accompany any genuine 925 Ksj marked items

3. Look at the packaging in which your jewelry arrives; usually genuine pieces will be sealed with plastic or have anti-tarnish linings which can provide additional protection against oxidation

4. Examine the detailing of rings carefully – does engraving on bands look authentic? Are there embossing patterns? Genuine pieces often feature quality craftsmanship from very skilled artisans.

5. Compare prices; if you find two identical items for sale at wildly different prices then chances are one isn’t genuine

By taking these steps you can help reduce the risk of purchasing counterfeit 925 Ksj marked pieces and invest in valuable jewelry that is more likely to stand the test of time.

Essential Tips for Preserving Valuable Jewelry with 925 Ksj Markings

925 Ksj markings signify that the piece of jewelry is made from sterling silver. Sterling silver is an alloy, meaning it is a mixture of metals, and it can be composed of many different metals. In this case the 925 indicates that 92.5 percent of the piece is pure silver and that 7.5 percent is another element such as copper or zinc. This makes it strong, durable and less susceptible to tarnishing – a frequent problem with silver jewelry.

To ensure lasting beauty, here are some tips for preserving sterling silver jewelry with 925 Ksj markings:

• Clean the jewelry on a regular basis with a polishing cloth designed specifically for sterling silver – even if no signs of tarnish are visible;

How Do You Clean Stainless Steel Jewelry

• Avoid exposing sterling silver to wearing lotions, hair products and perfumes as these will cause unwanted tarnish;
• Keep jewelry in airtight bags or containers;
• Store away from humid environments which will speed up tarnish;
• Do not let pieces come into contact with hard surfaces; and
• If possible use ultrasonic cleaners to keep your jewelry looking sparkly new!


925 Ksj is a marking that can be found on jewelry, and it signifies that the piece is made of sterling silver. Sterling silver is an alloy that consists of at least 92.5 percent pure silver combined with other alloys, such as copper or nickel. This makes the jewelry more durable than pieces made entirely of pure silver, while still maintaining its appealing look. Identifying the 925 Ksj marking on jewelry serves three key benefits: authentication, durability and protection of your investment.

Authentication – Being able to identify a marking like 925 Ksj means that you can confidently trust the authenticity of that particular piece or set of jewelry. The hallmark indicates to potential buyers and other parties that the item is indeed crafted with authentic sterling silver rather than being made out of a cheaper material like copper or nickel.

Durability – Jewelry marked with 925 Ksj will have excellent durability and will last for many years with proper care and maintenance. It won’t tarnish easily because it is composed primarily from alloy metals, which are less reactive to things in the environment such as humidity or oxygen. Though sterling silver needs periodic cleaning, any losses due to wear-and-tear over time will be less noticeable when compared with pieces fashioned from pure silver alloyed with lesser metals rather than stainless steel alloys as found in 925 Ksj markings .

Protection Of Investment – Knowing what 925 Ksj means also provides reassurance when considering making a large purchase decision when buying jewelry knowing that you are investing in an item that has been crafted genuinely from sterling silver; i.e., one of the most valuable non-precious metals available on the market today. Furthermore, this type of hallmark can provide evidence to potential purchasers should you decide in future years to sell it off or pass it down through generations in your family
