AU is the symbol for gold... 925 refers to the purity of that particular piece...
925 Au refers to gold that is 92.5% pure, which is equivalent to 22 karats. The remaining 7.5% typically consists of other metals, such as silver or copper, to enhance durability. Therefore, 925 Au is not 22 karats, but rather a way to denote the gold content in a piece of jewelry or metal.

Those are the initial of the company or maker.
925 usually refers to sterling silver, being 92.5% silver with 7.5% copper. However, Au is the chemical symbol for gold. Being that gold purity is usually marked in karats, it may indicate gold-plated sterling silver.
I had the same question. And there seems to be some contradiction in AU. I have found a maker of the name Archibald Ure a silver and gold smith from Edinburgh, Scotland 1700-1730. However, I don’t believe the earrings I have, and are marked 925 AU c, are from 1700s. I haven‘t found any other makers with the copyright AU yet.
"925-10k au" refers to the purity of gold in jewelry or other items. "925" indicates that the item is made of 92.5% silver and is often associated with sterling silver, while "10k au" signifies that the gold content is 10 karats, meaning it contains 41.7% pure gold. Together, this notation suggests that the item may contain a combination of both sterling silver and 10-karat gold components.
The "au" on a 10k necklace indicates that the piece is made of gold, as "Au" is the chemical symbol for gold on the periodic table. The "10k" signifies that the gold content is 10 karats, meaning it contains 41.7% pure gold and the rest is made up of other metals. This alloying process enhances durability while still maintaining some gold qualities.
