750, 585, 417 Gold Jewelry Markings and What They Mean

What Do the 750, 585, and 417 Markings on Gold Jewelry Mean?

As a professional gold buyer, I had to know all about jewelry markings in order to buy and resell scrap gold jewelry for profit.

Markings like 750, 585, and 417 often cause confusion among consumers. Most folks don't know what these mysterious combinations of numbers mean. It can be even more confusing if there are letters involved as well.

Caratage and Fineness: Understanding Gold Purity

Since pure gold is too soft to use for jewelry making, it is combined with other metals to make it stronger. Caratage and fineness both refers to the purity of gold in a gold alloy. Caratage signifies the number of karats in it, whereas fineness refers to parts per thousand of gold in an alloy.

Each gold variety (from 8K to 24K) has both a caratage and a decimal fineness. Pure gold equals 24 karats, or 24k, a caratage that can also be expressed in decimal form as .999 fine. Gold can never be 100% pure since there are always some impurities in it. The finest gold ever created was .999999 fine. The decimal is found by dividing the actual caratage by 24, the most carats gold can have.

For example:

  • 14 karat gold is .583 fine because 14/24 = .583.
  • It is 58.3% gold, and 583 parts out of 1000 are pure gold.

Therefore, the gold markings of 750, 585, and others refer to the purity of gold and correspond with a caratage.

Gold Purity Markings: Common Stamps

Here is a list of common gold markings. Notice that the marking 585 is associated with 14K (14 karat) gold. Why? In the example above we found that 14K gold is actually .583 fine. However, a 585 gold marking is also used to indicate 14K gold. The same applies to the marking 417, which indicates 10K gold, and 917, indicating 22K.

Since gold standards vary around the globe, there are some other consistencies like this that you'll find if you continue buying and selling gold.

Other Gold and Silver Markings and Stamps: Hallmarks and Maker Marks

Gold Jewelry Markings & Stamps
Gold Jewelry Markings & Stamps

Common gold stamps may be accompanied by one or more obscure secondary markings. People frequently ask what these other stamps mean. They can be numbers, letters or logos.

Most secondary markings on contemporary jewelry simply indicate the maker. They can also be the initials of a previous owner (in the case of a used item). There are almost as many different makers marks as there are gold rings! If you're dedicated to finding out who made your jewelry piece, it's certainly possible but be ready to do a lot of digging.

The picture shows a gold item with several different marks, including a 750 which means that it's 18K gold. Using the labels at the top of the picture as a key, you can identify the marks.

  • LAO indicates the jewelry maker.
  • The crown indicates the assay office (institutions that test the purity of metals).
  • 750 indicates the gold is 18k.

What to Watch Out for If You Want to Buy or Sell

Some symbols and letters indicate that the piece is not solid gold. See below for some markings that show the gold is electro-plated, filled, or rolled.

Some Other Common Markings and What They Mean

Symbol
Meaning
HGE
Heavy gold electroplate
RGP

Some hallmarks or stamps may indicate that the gold is not real.
