A "C in a Circle" stamped on an earring typically indicates that the piece is made by the jewelry brand "Chanel." This mark is a symbol of authenticity and signifies that the earring is a genuine product from the luxury fashion house. It's often found on their jewelry pieces, ensuring that buyers recognize its value and craftsmanship.
GEMHK was a trademark used by Fredrick Goldman on fine jewelry between the years 2000 and 2007ish. Your piece also has a c in a circle meaning copyright
The marking "14kt" indicates that the earrings are made of 14 karat gold, which contains 58.3% pure gold and is commonly used in fine jewelry. The letters "g," "c," and "j" could represent the manufacturer's initials or a specific design code, but their exact meaning may vary by brand or maker. It's best to consult with a jeweler for precise identification.
Common jewelry hallmarking or stamping is indication of purity of the metal. A K is used in stamping gold purity, a C would be used to indicate the weight of a gemstone. 14K indicates that it is 14 parts gold out of 24.
When jewelry is stamped with "C2," it typically indicates that the piece is made of a metal alloy containing at least 92.5% pure silver, which is known as sterling silver. The "C" stands for "coin," indicating that the silver used is of a high quality similar to that used in coins. The number "2" may refer to the specific manufacturer or designer of the jewelry, or it could be a code for the type of silver or the production batch.
MTL could mean 'Metal' however, I also have a ring with MTL stamped on it but I am unsure of what it really does mean. I would advise you to get it checked out at a jewellers and see what it means
A charm stamped "C C O 10k" indicates that it is made of 10 karat gold. The "C C O" may be the manufacturer's mark or initials. The charm is likely made of a gold alloy containing 10 parts of gold and 14 parts of other metals.
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.
"CA" stamped in a ring typically stands for "California." This stamp may indicate where the ring was manufactured, where the metal was sourced, or it could simply be a design choice by the jewelry maker.
The "c" with an arrow symbol on jewelry typically represents "carat," a unit of measurement for the weight of gemstones. The arrow indicates that the jewelry is designed to showcase the stone's weight and quality. This symbol is often used in marketing to signify that the piece contains a certain carat weight of a diamond or other precious stone.
