Have you ever found yourself deep in a reorganization of your jewelry drawer asking yourself what all the markings on these beautiful pieces mean? I know I have. Though the cryptic nature of the markings may seem romantic to some, I am always curious to know what these marks mean - and how they came to be. These markings remind me of the countless hands that have shaped and molded precious metals into objects of desire and meaning throughout human history.
The lifelong journey of a piece of jewelry begins long before it graces a wearer. It starts deep within the earth, where gold, silver, and other precious metals lie hidden, waiting to be unearthed. The process of mining these treasures is as old as civilization itself, a testament to our enduring fascination with that which shimmers and shines.
Once extracted, these raw materials undergo a scientific transformation that leads to an artistic transformation. They are melted, purified, and combined in precise ratios to create alloys that balance beauty with durability. It is in this alchemy that the markers on jewelry find their origin – each character a silent guardian of quality and composition.
At Jack Weir & Sons, we revere the tradition of jewelry making and know that the numbers and letters stamped onto each piece are not mere afterthoughts but integral parts of the creation process, ensuring that every item we find for you meets exacting standards of purity and craftsmanship.
So as we delve into the meaning behind these cryptic markings, remember that these digits are not simply random but a code – a language that speaks volumes to those who understand it (including you after you read this article!)
Let us begin with the numbers, those seemingly innocuous figures that hold such significance.
SILVER & PLATINUM
925 – This number, perhaps the most commonly seen, indicates sterling silver. It tells us that the piece is composed of 92.5% pure silver, with the remaining 7.5% typically being copper or another metal to provide strength. The Hermes bracelet below is sterling silver and thus would be marked with the 925 tag.
950 – A step above sterling, this marking denotes 95% pure platinum. In the world of platinum jewelry, 950 is the standard of excellence, representing an alloy that is both rare and resilient. The platinum, diamond and sapphire bracelet below would be marked with 950 to denote it's platinum base.
800 – Less common in modern jewelry, this number harks back to a different standard of silver purity, indicating 80% silver content. It's a reminder that standards evolve, much like fashion itself.
GOLD
585 – Here we enter the realm of gold, with 585 signifying 14 karat gold, an alloy containing 58.5% pure gold. This popular choice balances the rich color of gold with improved durability for everyday wear. The gold tubogas necklace below would be marked with a 585 to signify that it's made of 14 karat gold.
750 – Moving up the scale of golden luxury, 750 marks 18 karat gold, boasting 75% pure gold content. It's a number that whispers of opulence and tradition. The Cartier gold band below would be marked with a 750 to denote that it's made of 18 karat gold.
417 – This less common marking indicates 10 karat gold, the minimum karat weight that can be legally marketed as gold in the United States. It's a number that speaks to accessibility without sacrificing the allure of gold. The Retro Sapphire ring below would be marked with a 417 to denote its makeup of 10 karat gold.
333 – In some European countries, this number denotes 8 karat gold, a composition rarely seen in American jewelry but a testament to the global nature of the craft.
K or KT – These letters that come after a number, indicate the karat weight of gold. 14K, 18K, 24K – each a measure of purity and value. A brooch like the one below would be marked 18K to denote that it is made of 18 karat gold.
PLAT – An abbreviation for platinum, the most precious of metals, known for its rarity and durability. The drop earrings below would be marked with PLAT.
STG or STER – Short for sterling silver, often accompanying the number 925.

GF or G.F. – Gold Filled, a technique where a layer of gold is bonded to a base metal, creating a more affordable alternative to solid gold.
GP or G.P. – Gold Plated, signifying a thin layer of gold applied to a base metal through electroplating.
HGE – Heavy Gold Electroplate, a thicker layer of gold than standard plating, offering more durability.
RGP – Rolled Gold Plate, another method of applying gold to a base metal, often resulting in a thicker gold layer than standard plating.
SS – Stainless Steel, a modern alternative in jewelry making, prized for its strength and resistance to tarnishing.
999 – The pinnacle of purity, this number is reserved for fine gold and fine silver, indicating 99.9% purity. It's a rarity in jewelry due to the softness of such pure metals, but it exists as a beacon of uncompromising quality.
As we explore these markings, it's important to note that the language of jewelry has evolved over time, reflecting changes in technology, fashion, and even global events. During the Retro era of the 1940s and 1950s, for instance, jewelry often bore lower numbers and utilized more blended types of metal. This was not a stylistic choice but a necessity born of the scarcity of precious metals during and after World War II. In these pieces, we see history written in gold and silver, a tangible reminder of how world events shape even our most personal adornments.
The stones set within these metal frameworks also tell their own stories. At Jack Weir & Sons, one might find a dazzling array of gemstones – from the fiery brilliance of diamonds to the deep blue depths of sapphires, each carefully selected and set to complement the metal that cradles it. The numbers and letters on the jewelry holding these stones are like silent promises, assuring the wearer of the quality and authenticity of their piece.
When you really take the time to consider what one might find in their jewelry collection, you might be struck by how these tiny markings connect us to a vast network of human endeavor. From the miners who first unearthed the gold to the craftsmen who shaped it, from the assayers who verified its purity to the loved one who chose it as a gift – each digit is a link in a chain that stretches across continents and generations. In the end, the value of jewelry lies not just in its material worth but in the stories it carries. The digits etched into metal are more than a guarantee of quality; they are a form of provenance, a way of tracing our personal histories through the objects we cherish. They remind us that even in our most intimate possessions, we are connected to a larger world of craft, commerce, and human expression.
In the carefully curated selection at Jack Weir & Sons, each piece tells its own story, marked with digits that assure its quality and authenticity. Whether you're drawn to the timeless elegance of platinum, the warm glow of gold, or the cool sheen of silver, understanding these markings allows you to make informed choices and appreciate the true value of your jewelry.
