Our Platinum
At USA Jewels, we use only the highest quality platinum in every piece we manufacture. Platinum is one of the rarest precious metals on earth—roughly 30 times rarer than gold—and its natural white luster, extraordinary durability, and hypoallergenic properties make it the premier choice for fine jewelry. Unlike white gold, which requires rhodium plating to achieve its bright finish, platinum is naturally white and will never yellow or fade. That inherent color is why platinum has become the standard setting metal for diamond rings and high-end jewelry: it enhances the brilliance and fire of diamonds without competing with their sparkle.
Platinum is also the densest precious metal used in jewelry. A platinum ring feels noticeably heavier than the same ring in gold, giving it a sense of substance and permanence that many customers describe the moment they pick one up. That density contributes to its strength—platinum prongs hold diamonds and gemstones more securely than gold prongs, which is why we recommend platinum settings for all valuable stones. When a gold prong wears down, the metal is lost; when platinum wears, the metal is merely displaced, meaning it stays on the piece rather than wearing away.
What Makes Platinum Different from Gold
Gold and platinum are both excellent jewelry metals, but they behave differently in ways that matter to the wearer. Color is the most visible difference. Yellow gold has a warm tone, white gold is plated to appear silvery-white, and platinum is naturally white with a slightly cooler, more gray undertone than rhodium-plated white gold. Over time, white gold will show its underlying yellowish alloy as the rhodium wears off. Platinum never changes color.
Weight is the next thing people notice. Platinum is about 60% heavier than 14K gold. A platinum chain or bracelet has a satisfying heft that many customers prefer. For platinum chains, that extra weight translates into a drape and feel that lighter metals cannot replicate.
Durability sets platinum apart in a practical way. While gold is a harder metal on the surface, platinum is far more resistant to metal loss over time. Gold scratches and loses tiny flakes of metal with every scratch; platinum scratches too, but the metal simply moves from one part of the surface to another without being lost. This is why a platinum ring worn for 20 years retains virtually all of its original metal, while a gold ring loses a measurable amount. For pieces worn daily—especially rings and bracelets—this longevity matters.
Hypoallergenic is another key advantage. Platinum jewelry at 95% purity contains almost no alloys that trigger skin reactions. People with nickel sensitivities or metal allergies can wear platinum with confidence. This makes it an especially good choice for wedding bands and engagement rings that are worn around the clock.
Platinum in Jewelry
Platinum's combination of strength, beauty, and rarity has made it the metal of choice for the world's most important jewelry for over a century. The Hope Diamond, the Star of Africa, and many other legendary gems are set in platinum. Cartier, Tiffany, and other prestigious houses adopted platinum in the early 1900s because no other metal could hold intricate filigree work and micro-pavé settings as securely.
For everyday jewelry, platinum performs exceptionally well in several categories. Engagement rings and wedding bands are the most popular platinum pieces because the metal's strength protects center stones and withstands a lifetime of daily wear. Platinum chains are available in styles ranging from delicate cable chains and box chains to substantial rope chains and curb chains. The natural white color makes platinum chains particularly striking against darker clothing and skin tones. Platinum earrings are ideal for anyone with sensitive piercings, and platinum pendants in Franco or wheat chain settings provide a secure, elegant showcase for diamonds and gemstones.
Platinum Patina
One characteristic unique to platinum is the development of a patina—a soft, satiny finish that forms naturally as the surface accumulates fine scratches over time. Unlike scratches on gold that remove metal, platinum scratches simply redistribute the metal across the surface, creating a matte, lived-in look that many jewelry enthusiasts actually prefer to the original mirror polish.
This patina is a matter of personal taste. Some customers love the way a patina gives platinum jewelry a warm, vintage character and a soft glow rather than a sharp reflection. Others prefer the bright polished look and bring their platinum pieces to a jeweler periodically for repolishing. Either way, the metal is not being damaged—it's simply changing its surface texture. A jeweler can restore a mirror finish to a patinated platinum piece in minutes, and no metal is lost in the process.
Platinum Jewelry Care
Platinum is one of the lowest-maintenance precious metals, but a few simple habits will keep it looking its best. For regular cleaning, soak platinum jewelry in warm water with a few drops of mild dish soap for 15 to 20 minutes. Use a soft-bristle toothbrush to gently scrub around settings, inside chain links, and any textured areas where oils and lotion accumulate. Rinse under clean running water and pat dry with a lint-free cloth.
What to avoid: Remove platinum jewelry before using harsh chemicals, bleach, or chlorine-based cleaners. While platinum itself is highly chemical-resistant, gemstones set in platinum may not be. Take off platinum rings and bracelets before heavy manual work or the gym—not because the metal is fragile, but because impacts can loosen stone settings over time. Swimming in chlorinated pools is generally fine for platinum metal, but we recommend removing pieces with gemstone settings as a precaution.
Professional maintenance: Bring your platinum jewelry to a jeweler once or twice a year for inspection. They will check prong integrity, tighten any loose stones, and offer polishing if you prefer the bright finish over the natural patina. For platinum rings worn daily, an annual prong check is especially important to ensure your center stone remains secure.
Platinum Purity and Markings
Platinum jewelry sold in the United States must meet strict purity standards established by the Federal Trade Commission. At USA Jewels, all of our platinum jewelry is manufactured from 950 platinum—95% pure platinum by weight, with the remaining 5% consisting of complementary alloys such as iridium, palladium, ruthenium, or cobalt. These alloys are carefully selected to enhance workability and hardness without compromising platinum's natural properties.
The platinum standard is measured in parts per thousand, where 1000 parts equals 100% purity. Only jewelry containing at least 950 parts per thousand of platinum can be stamped simply as “Platinum” without further qualification. Jewelry containing 850 to 949 parts must identify the specific alloys used. Below are the most common platinum alloys found in fine jewelry:
| Purity |
Metal |
Description |
| 95% |
Platinum |
950 parts per 1000 of platinum and 50 parts other metal. This is the standard for fine platinum jewelry in the US. Commonly stamped as “Platinum”, “Plat”, “Pt”, “Pt950”, or “950Pt”. This is the purity USA Jewels uses for all platinum jewelry. |
| 90% |
Platinum |
900 parts per 1000 of platinum and 100 parts other metal. Slightly harder than 950 due to higher alloy content. Commonly stamped as “900Pt”, “Pt900”, or “900Plat”. |
| 85% |
Platinum |
850 parts per 1000 of platinum and 150 parts other metal. Must be stamped with the alloy name, such as “850Pt 150Ir” (platinum with iridium) or “850Pt 150Pd” (platinum with palladium). |
Platinum vs. White Gold
This is one of the most common questions we hear from customers, and the answer depends on your priorities. White gold is a gold alloy (typically mixed with palladium or nickel) that is plated with rhodium to achieve a bright white finish. It is lighter than platinum, less expensive, and widely available. However, the rhodium plating wears off over time—usually within one to three years depending on wear—revealing the slightly yellowish alloy underneath. Re-plating is a quick and inexpensive service, but it is an ongoing maintenance requirement.
Platinum is naturally white and never needs plating. Its color is permanent and consistent throughout the entire piece, not just on the surface. Platinum costs more upfront, but you avoid the recurring cost and inconvenience of rhodium re-plating. For customers who want a truly white metal that stays white forever, platinum is the clear choice. For those who prefer a lighter feel on the finger and want to save on the initial purchase, white gold is an excellent alternative—explore our gold rings to compare styles and pricing.
Is Platinum Worth the Investment?
From a pure metal perspective, platinum typically trades at a premium to gold on the commodities market, though prices fluctuate. A platinum piece contains more precious metal by weight than a comparable gold piece, which supports its resale and melt value. But the real value of platinum jewelry goes beyond the metal market. Platinum pieces last longer, require less maintenance, and retain more of their original metal over decades of wear.
For engagement rings and wedding bands that will be worn every day for a lifetime, platinum pays for itself in longevity. The prongs hold tighter, the band loses no metal, and the natural patina tells the story of years worn. If you are starting from scratch, our design your own diamond ring tool lets you build a custom platinum setting around the perfect stone. For chains and pendants, platinum offers a distinctive look and weight that gold cannot match—browse our platinum chain collection to see the full range of styles available. For customers who appreciate the best and plan to keep their jewelry for generations, platinum is the finest choice you can make.
