916, 917 – 22 karat gold. 833 – 20 karats. 750 – 18 karats. 625 – 15 karat gold.
.833 = 20 carat (Asia) .999 (1000) = 24 carat pure gold. Strictly speaking, 14 carat should be 583 (14/24 = . 583333), but most manufacturers have adopted the European practice of making 14 carat gold slightly over 14 carat. Thus, the fineness mark is 585 in most 14 carat gold jewellery.
'875' gold is just one of many different types of hallmarks. If a gold product bears the hallmark '875', then your gold has been tested and classed as 21 carat or 87.5 per cent pure. The remaining 12.5 per cent of the item is composed of different metals such as nickel, copper, or in some cases silver.
750 means 18-karat gold. 585 means 14-karat gold. 417 means 10-karat gold.
Q: WHAT IS 825 JEWELRY? A: The 825 stamp on jewelry is the same as 19 Karats of gold; for example, an 825 ring represents a purity rating of 82.5 percent, meaning an 825 ring contains more than 82 percent gold.
Also, if the item appear to be a gold alloy, then 835 would equal 20 Karat (or Carat in the UK and Europe) gold.
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.
European gold jewelry is often stamped with a 3-digit number—417, 585, or 750--to specify the purity of the gold. In this case the number refers to how many parts out of 1000 are gold. For instance, a 14K item would be marked “585,” indicating that 585 particles out of 1000 are gold.
Acid test.
An acid test can reveal the karat of solid gold jewelry, but it can also show whether jewelry is solid gold or gold-plated. With an acid test, a small sample of the jewelry is removed and exposed to acid to induce a color change. The resulting colors indicate which type of metal the jewelry is made of.
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.
“Fineness” defines gold content in parts per thousand. For example, a gold nugget containing 885 parts of pure gold and 115 parts of other metals, such as silver and copper, would be considered 885-fine. “Karat” indicates the proportion of solid gold in an alloy based on a total of 24 parts.
The 825 number on jewelry tells us that this gold jewelry is made of real and pure gold, and by looking at 825 number, we can also ascertain the purity of gold. 825 means 82.5 % Pure gold is present in it and it is 19 carats Gold.
Again, “925 gold” doesn't actually exist. This hallmark only indicates the purity of the sterling silver base beneath the gold. Knowing this, you should be aware that gold jewelry with a 925 hallmark or stamp is typically going to be less valuable than solid gold jewelry.
Pure gold is notated as 24K – this is the highest karat level for gold meaning it is 100% pure gold. 18K gold is 75% purity level, 14K is 58.3% purity level, and 10K is 41.7% purity level. As you can see, the higher the karat number, the more pure gold comprises the metal.
24 Karat Gold: 24K gold signifies 99.9 percent purity and also called pure gold as it doesn't contain traces of any other metals. One should know that there is no higher form of gold than 24K.
The answer is yes; you can absolutely pawn gold plated jewellery, but it depends on the base metal. Pawning gold plated jewellery is really only ever worthwhile if the base metal of your item is made of a precious base metal like silver.
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. If that necklace leaps to the magnet, your significant other has some explaining to do.
On the other hand, a piece may be gold plated, but it will not attach to a magnet because its core metal is non-magnetic.

If the piece is real gold, the stamp should bear a manufacturer's mark and a karat marking, such as 14K or 24K. Fake gold may bear a karat mark, but will not have a manufacturer's mark.
83.5% purity – 835 thousandths. 80% purity – 800 thousandths. Purity Verification and Marking.
830 mark used before 1927, denoting the 83% silver content used before going to the sterling standard. Also present is the GI 830S mark as well. Often earlier pieces could be stamped multiple times.
If you see a karat marking like K or k, usually accompanied by a number, the item is made of white gold.
