If you enjoy wearing fashionable jewelry, you may want to know if the jewelry you’re buying is made of stainless steel. This is especially important if you have allergies to other types of metals.
Next, we’ll share some simple tips to help you identify whether a piece of fashion jewelry is made of high-quality stainless steel.
Ask the Seller
If you’re unsure about the composition of fashion jewelry, asking the seller is always a good option. They can provide more information about the jewelry.
Feel Your Jewelry
Stainless steel is a heavy and dense metal, and you can judge by its weight. If a piece of jewelry feels heavier compared to similar pieces, it might be steel. Note that jewelry of different designs and sizes can vary significantly in weight, so this method is more applicable when comparing similar types and sizes of jewelry.
Inspect the Surface
The surface of stainless steel jewelry is very smooth and polished. If you notice a dark color or significant fading, it’s likely not stainless steel. Stainless steel jewelry has a bright, shiny finish after polishing, which is a major distinguishing factor.
Hardness Test
Stainless steel is very hard and resistant to scratching. You can lightly scratch the surface of the jewelry with a softer item like a copper coin or a key and observe if it leaves any marks. If the surface easily scratches, it might not be stainless steel.
Finding Marks
A quick and simple method is to check for marks on jewelry. For example, look for markings like “SS,” “316L,” or other numerical indicators to verify if the jewelry is stainless steel. Many stainless steel jewelry pieces are labeled with “Stainless Steel” or “SS,” indicating the grade of stainless steel used.
Gold Marks
For gold jewelry, the numbers inscribed on it will tell you if it’s pure gold or gold-plated silver, and the karat of the gold. If it bears one of these numbers, it’s pure gold:
375 = 9 karat
585 = 14 karat
750 = 18 karat
916 = 22 karat
990/999 = 24 karat
If the numbers on your gold jewelry match those listed under silver marks in the next section, it indicates it’s made of gold-plated silver. Thus, the piece will be classified as silver for recycling. If your gold jewelry lacks markings, it’s likely gold-plated brass.
Silver Marks
Silver numbers differ from gold numbers. If you find one of these numbers on your silver jewelry, it indicates it’s made of silver:
800
925 (Sterling Silver)
958
999
Stainless Steel Marks
- Numerical Markings
One common marking on stainless steel jewelry is a number, often indicating the specific type of stainless steel. The most common numerical markings include:
316L
304
- Alphabetical Markings
In addition to numerical markings, stainless steel jewelry may also have alphabetical markings, representing characteristics of stainless steel or the manufacturer’s logo. For example:
SS: Represents Stainless Steel, a general mark indicating the jewelry is made of stainless steel.
SUS: Particularly common in Asian markets, denotes stainless steel (often Japanese standard).
However, note that some unethical vendors may inscribe these markings on non-stainless steel jewelry. Further verification with other methods is advisable.
Magnet Test
The magnet test is a simple and effective method to determine if your stainless steel jewelry is genuine. This method works because authentic stainless steel is not magnetic, whereas other metals like nickel or iron are magnetic. By testing whether your jewelry is attracted to a magnet, you can quickly and easily determine if it’s made of genuine stainless steel.
Steps for Magnet Test
Performing the magnet test is straightforward and requires only a magnet and your jewelry:
- Step 1: Prepare a magnet, which can be a household refrigerator magnet or any other strong magnet.
- Step 2: Bring the magnet close to different parts of the stainless steel jewelry, such as the chain or clasp.
- Step 3: Observe if there is a magnetic reaction. If the jewelry is attracted to the magnet, it is likely not made of genuine stainless steel. If the jewelry is not attracted to the magnet, it is likely made of genuine stainless steel.
Acid Test
Stainless steel exhibits excellent corrosion resistance. You can conduct an acid test by placing a few drops of vinegar on the surface of the jewelry and observing for any color change or rust.
If your jewelry is stainless steel, which contains chromium, it will not react with the acid. However, other metals may develop rust spots in a short time. Note that this method should be used cautiously to avoid unnecessary damage to the jewelry.
Corrosion Resistance Test
A notable characteristic of stainless steel is its corrosion resistance. Conducting a simple corrosion resistance test can help identify the material of the jewelry.
Steps:
- Prepare some warm water and table salt, mixing them to create a saltwater solution.
- Immerse the jewelry in the saltwater solution and wait for several hours.
- Remove the jewelry, dry it off, and observe for any signs of corrosion.
Note that this method has the potential to damage non-stainless steel jewelry, so use it with caution.
Cleanliness Test
If you’re unsure whether an item is made of stainless steel, you can perform a cleanliness test. Stainless steel is easy to clean and resists staining. Try cleaning the item with mild soap and warm water. If the item remains unstained and retains its shine, it’s likely made of stainless steel.
Professional Testing
If the above methods still cannot determine the material of the jewelry, the most reliable method is to have it professionally tested at a jewelry appraisal institution. Professional organizations have advanced testing equipment and techniques to accurately analyze the material composition of jewelry.
