Precious Metals for Jewelry
Gold, silver, platinum and palladium
Precious metals are the rare, chemically resistant metals treasured for jewelry, coinage and art across civilizations: principally gold, silver, platinum and palladium, with rhodium, iridium and ruthenium used in smaller jewelry roles such as plating and alloying. Gold brings its warm yellow color, malleability and freedom from tarnish, measured in karats. Silver brings bright white luster at the most accessible precious price, in sterling form for jewelry. Platinum and palladium bring natural whiteness, density and durability, with platinum the premier setting metal for important stones. This guide covers each precious metal's properties and jewelry uses, purity systems, hallmarks, prices in relation to one another, and the care each asks, including silver tarnishing, the one maintenance task precious metals impose.
Precious metals are a category of metallic elements that hold a unique and enduring allure due to their rarity, beauty, and inherent properties. These metals have been treasured by various civilizations throughout history for their use in currency, art, and jewelry. The primary precious metals include gold, silver, platinum, and palladium, while other elements like rhodium, iridium, and ruthenium are also considered precious but are less commonly used in jewelry. Here's a detailed look at each of these precious metals and their traits:
Gold:
- Gold is one of the most coveted precious metals and is known for its stunning yellow color and malleability.
- It is highly corrosion-resistant and does not tarnish or rust.
- Gold is a great conductor of electricity and is used in electronics.
- It has been used for thousands of years in jewelry, coins, and religious artifacts.
- The purity of gold is measured in karats, with 24-karat gold being 99.9% pure.
Silver:
- Silver is characterized by its shiny, white luster.
- It is less expensive than gold but still highly prized for its beauty.
- Silver is more malleable and ductile than most other metals, making it ideal for intricate jewelry designs.
- Like gold, silver has antibacterial properties, making it suitable for use in medical instruments.
- Sterling silver is a popular alloy consisting of 92.5% silver and 7.5% other metals, typically copper.

Platinum:
- Platinum is a dense, silvery-white metal known for its rarity and durability.
- It is hypoallergenic and highly resistant to corrosion and tarnish.
- Platinum is often used in engagement and wedding rings due to its durability and purity.
- It is more expensive than gold, making it a symbol of prestige and luxury.
- Platinum jewelry is typically 95-99% pure platinum.
Palladium:
- Palladium is a silver-white metal closely related to platinum.
- It is lightweight, strong, and hypoallergenic.
- Palladium is often used as an alternative to platinum, especially in men's wedding bands.
- It is less dense and less expensive than platinum but still valuable.
Among these precious metals, gold and platinum are the most popular choices for jewelry due to their timeless appeal and durability. Gold, in particular, is available in various colors, including white, yellow, and rose, allowing for a wide range of design possibilities.
In terms of cost, platinum is generally the most costly precious metal used in jewelry design due to its rarity and density. Gold comes in various price ranges, with 24-karat gold being more expensive than lower-karat alloys. Silver and palladium are relatively more affordable options.
The historical significance of using precious metals in jewelry compared to non-precious metals is profound. Precious metals have been associated with wealth, power, and status for centuries. They were used to create intricate and valuable adornments for royalty, nobility, and religious figures. The rarity and beauty of these metals symbolized luxury and excellence.
Non-precious metals, on the other hand, were historically more common and accessible to the general population. They were used for more utilitarian purposes and often lacked the luster and durability of precious metals. As a result, jewelry made from precious metals has held a special place in human culture and continues to be cherished for its symbolism and aesthetic value.

Value That Outlasts Fashion
Precious metals hold a dual position no other jewelry material matches: a piece is simultaneously an ornament and a store of metal value, which is why gold and platinum jewelry is repaired, restyled and inherited rather than discarded. Their chemistry supports that permanence. Gold and platinum barely react with air, water or skin, silver tarnishes only at the surface, and all of them can be melted and reworked indefinitely without loss, a recyclability jewelers have relied on for thousands of years.
For buyers, the practical system is stamps and weight: confirm the karat or fineness mark, feel the density that distinguishes platinum and gold from plated substitutes, and pay for workmanship knowing the metal itself retains value. The companion guides cover the non-precious metals that now compete with precious metals on performance, and tarnishing in detail. A precious-metal piece bought with its marks understood is the closest jewelry comes to a permanent possession, and its pages in this section, for gold, silver and platinum in every jewelry type, show what that permanence can look like.
Common Questions
Which metals are considered precious in jewelry?
Gold, silver, platinum and palladium are the four jewelry precious metals. Rhodium, iridium and ruthenium belong to the same platinum family and are precious, but in jewelry they appear mainly as rhodium plating over white gold and silver, and as alloying metals that harden platinum and gold, rather than as the body of a piece. Scarcity, resistance to corrosion, beauty and a long monetary history are what define the group.
How is the purity of precious metals measured?
Gold is measured in karats, with 24 karat being pure and common jewelry at 18, 14 and 10 karat, also stamped 750, 585 and 417. Silver jewelry is usually sterling, 92.5 percent silver, stamped 925. Platinum jewelry is typically 95 percent platinum, stamped 950, and palladium similarly 950. These stamps, together with a maker's mark, are the buyer's guarantee, and reputable precious-metal jewelry always carries them where the design allows.
Why does platinum cost more than gold in jewelry?
Platinum is rarer, denser, so a piece uses more metal by weight, harder to work, requiring higher temperatures and specialist tools, and used at higher purity, 95 percent against gold's 58 to 75 percent in common karats. Those factors together usually price platinum jewelry above comparable gold pieces, though market prices for the two metals move independently and the metal-price gap alone does not tell the whole story. Palladium shares platinum's family and whiteness at a lighter weight.
