So, what does a 925 mark mean when stamped on jewelry? The 925 stamp indicates that the piece of jewelry you're holding has been created with sterling silver. Sterling silver is an alloy that is made of 92.5% actual silver, with the rest of the metal made up of base metals like copper.
Here are some of the most common jewelry hallmarks: Karat (KT or K) - Indicates the purity of gold, the higher the karat number, the purer the gold. Fine Silver (FS) - Indicates that a piece consists of at least 99.9% pure silver. Sterling Silver (SS) - Indicates that a piece consists of at least 92.5% pure silver.
Sk9 stamps denote that a piece of jewelry is made out of platnaire. Platnaire is a hypoallergenic alloy. Platnaire consists of 5% platinum, 92.5% silver, and 2.5% other elements. This metal never contains nickel, which is why it is considered safe for sensitive skin.
If you see 925 engraved on the ring, that means it's a sterling silver setting. Usually, engagement rings with a larger center diamond won't be set in sterling silver because it's too soft. And if you see a stamp that says "CZ," you're looking at a cubic zirconia stone, rather than a real diamond.
925 silver oxidizes when exposed to air leading to chemical changes in its wake. Using a soft white cloth, rub a small part of the jewelry, if the surface produces a black mark it would mean that the product is sterling silver. On the other hand, the color change would be absent in fake merchandise.

These stamps stand for sterling silver. This means the piece of jewelry should be 92.5% pure silver mixed with another metal, usually copper. Silver on its own is very soft and needs another metal added to make solid jewelry.
What is the stamp for diamonds on a ring? It depends on whether or not the diamond is natural or lab-created. If it's a real diamond, you can expect to see a stamp with carats and points. If it's made of synthetic gemstones like Cubic Zirconia, you may see a CZ mark.
In fact, 92.5% is not a recognized value for gold. If you find a piece of gold jewelry with 925 or some variation stamped on it, odds are very good the piece isn't solid gold. It's instead likely the piece's base is sterling silver and gold has been plated or otherwise applied atop the base.
Not necessarily. If you have a gold piece with a 925 mark, it's most likely sterling silver underneath gold plating. You'll normally see this kind of stamp on a gold vermeil (pronounced as "ver-may"), meaning that it's sterling silver that has gold plating.
925 silver, often referred to as sterling silver, is, in fact, real silver though it is an alloy rather than pure silver. 925 silver means your item is 92.5% silver and 7.5% another metal, such as copper. This means that your 925 silver is valuable and can be sold.
SK means "It's OK" and "Spawn Kill." The abbreviation SK is widely used online and in text messaging to mean "It's OK." It is also used in online gaming to mean "Spawn Kill."
"SK" is a morse code prosign meaning "silent key," indicating the last transmission from a station.
Sterling silver is an alloy made up of 92.5% pure silver and 7.5% other metals, usually copper or zinc. Sterling silver pieces are stamped with 925 to mark their authenticity.
In 18ct. white gold, the mix is three parts gold to one part palladium, hence the stamp “750” in 18ct.
Sterling silver, also known as 925 sterling silver, is a metal alloy used in jewelry and decorative household objects. Traditionally, it is 92.5% silver (Ag), and 7.5% copper (Cu).
10K gold is the least pure, least expensive, yet most durable, form of gold used widely in jewelry today. With its 41.7% gold purity, it's the most impure gold available on the market that can still legally be called “gold” in the US and most other countries.
Look for Stamps or Hallmarks in Your Gold Jewelry
Most real gold is stamped with a hallmark that indicates its purity, aka its karat. The karat is the unit used to measure the purity of gold. The higher the karat, the purer the gold. The most common karats you'll see are 10k, 14k, 18k, 22K, and 24k.
Specific Gravity of Gold
Specific gravity (SG) is used to compare the density of different materials in relation to water. If a given volume of a substance has a specific gravity of 2 it means that it is twice as heavy as the same volume of pure water.
What to do: Hold the magnet up to the gold. If it's real gold it will not stick to the magnet. (Fun fact: Real gold is not magnetic.) Fake gold, on the other hand, will stick to the magnet.
Apply a drop of acid to the scratched surface only.
Alternatively, use a drop of vinegar (which is highly acidic) on the scratched piece. If it's real silver, the surface won't get tarnished. If the silver is fake, it will tarnish.
No, silver is not magnetic. Test your jewelry with a strong magnet. Slowly move the magnet closer. If your piece snaps to the magnet, then it is not true sterling silver.
