The precious metal composition of the jewelry is indicated by the metal and purity mark. The number refers to the piece’s refinement, which is expressed in parts per thousand. 

For instance, a ring stamped with CZ indicates the use of cubic zirconia, and 925 indicates the presence of silver. In this article we have gathered all the information you need regarding H, 925 and CZ stamped on your piece of jewelry.  

What does H mean on jewelry? 

The maker’s mark identifies the item of jewelry’s creator or sponsor. As a result, the piece of jewelry may be fully traced. H stands for Hamilton Jewelers which was established in Lancaster, Pennsylvania in 1892. Bienne, Switzerland is now the company’s headquarters.  

What does the H 925 ring mean? 

H is a mark that indicates the name of the company that is Hamilton Jewelers. The 925 stamps on silver rings refer to the silver’s purity.  

It means that out of every 1000 bits of material in a piece of jewelry, 925 parts must be silver, and no more than 75 parts must be a different metal. It is made up of 92.5 percent silver and 7.5 percent another metal. 

What is H 925 jewelry? 

It holds the same meaning as H 925 on a ring. H means the company name that is Hamilton Jewelers. The 925 stamp signifies that the piece of jewelry you’re wearing is made of sterling silver. 

Sterling silver is an alloy that contains 92.5 percent silver and the rest is made up of base metals such as copper. The purity of the silver used is usually indicated by a stamp on most silver objects. 

What is its worth? 

You may come across a gold ring with the 925 hallmarks sometimes. As a result, when the hallmark indicates 925, it means there is silver underlying the thin gold covering. In such instances, you should not pay more than the silver ring’s true value.  

Unfortunately, the slight layer of gold will not add much to its value. CZ does not have the same value as diamond because it refers to cubic zirconia stones.  

Real stones can be found in silver jewelry, although man-made stones are far more popular. This is because silver is delicate and stones are easily misplaced. 


The worth of a ring can be predicted by the marks on that piece of jewelry. Each mark has its unique meaning. In this case, H is the hallmark of its maker called Hamilton. 925 means that the ring is made of sterling silver and CZ is a stone that is made in a lab called cubic zirconia.  

The worth of that ring is less than the gold ring and it will be available at affordable rates since the stone used in it is not diamond but lab-grown gemstone.
