A: The 333 jewelry mark means 8k gold, slightly less than 9k gold (375 gold). The 333 jewelry mark denotes the parts of pure gold out of 1000; in other words, 333 parts of pure gold out of 1000 total units equals 8k gold.
375 – 9 karats. 333 – 8 karat gold (typically the lowest one will find in German markets)
333 is 8k (8 karat) gold, slightly less than 9k gold which is called 375. The number denotes the parts of pure gold in 1000 parts of other metal. In other words, there are 333 parts of gold in your necklace, the balance being made up of other metals.
If a gold product contains the hallmark '375', that means your gold is 9 karat – or 37.5 per cent pure. The remaining 62.5 per cent of the product is an alloy of different metals, like nickel, copper, or in some cases silver.
Also, if the item appear to be a gold alloy, then 835 would equal 20 Karat (or Carat in the UK and Europe) gold.
Q: WHAT DOES 835 STAMPED ON JEWELRY MEAN? A: One of the many marks used to identify European silver jewelry is 835, which stands for 83.5% silver and 16.5% copper.
Much like an 935 silver mark, an 835 mark means that 835 parts out of 1000 are sterling silver, or the item is 83.5% pure sterling silver.
You may notice that some jewellerybox items have a 925 or 375 stamp. Although indicative of the metal purity, these stamps are not hallmarks and should not be taken as a guarantee of fineness. Beware of fake hallmarks that look all too legitimate from a distance.
If your gold is inscribed with the '375' hallmark, it means that it is 37.5 per cent pure, or 9 karat gold for short.
The angel number 333 encourages to set plans into action and let your personal strength be the guide; to trust yourself and put thought into your choices. This angel number also is connected with optimism, creativity and intuition.
333er gold has a fine gold amount of 33.3%. Jewellery made of 333er gold is often mixed with a very high percentage of copper. This jewellery is often recognizable by a slightly reddish gold tone. 585er gold has a fine gold amount of 58.5%.
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.
9ct gold contains 37.5% pure gold. 18ct gold contains 75% pure gold. The remainder is an alloy of other metals. The other metals are dependant on the colour of gold.
The more gold in the mix, the higher the carat weight and the higher the cost. Generally speaking, 18ct gold costs around twice as much as its 9ct gold.
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.
9ct gold is 9 parts pure gold or 37.5% pure, hence the stamp 375 found inside pieces made of this alloy. Due to this metals lower durability and tendency to tarnish, corrode and react with its wearers skin, Metal Urges choose not to work with it.
Look for a Letter Mark
If the item of jewelry has the letters GP, GF, or GEP stamped on it, these indicate that it is not made of real gold. GP means it is gold plated, GF means it is gold filled, and GEP means it is gold electroplate. That is, the jewelry is made of some other metal with a thin layer of gold on top.
It is an industry standard mark. It refers to the percentage of gold in the alloy. In this case it 32.5% (by weight) gold. This translates into 8kt gold.
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.
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.
