Platinum. Quietly Exceptional.
Platinum doesn't announce itself. It holds a diamond with more security than any other metal, wears without losing material, and never needs replating. Its case is made entirely by what it does.

The metal that moves, not wears.
Platinum is about 30 times rarer than gold. It's also denser — a platinum ring feels noticeably heavier than a gold ring of the same design, a quality many people find satisfying and substantial. That density isn't just about feel. It's structural. When platinum scratches, the metal displaces rather than wears away, which means the ring loses essentially no material over a lifetime of wear. Gold scratches differently — small amounts of metal are actually removed over time.
It's also naturally hypoallergenic and entirely free of the need for surface treatments. There's no rhodium plating, no color to maintain, no replating schedule. The cool, white-grey tone you see in a new platinum piece is the metal itself — and it stays that way. Over time, platinum develops a soft patina that many people come to prefer. It can always be polished back to its original brightness if that's what you want.
- Durability: 5 out of 5
- Tarnish Resistance: None - ever
- Color Permanence: Intrinsic
- Replating Needed: Never
- Hypoallergenic: Yes
- Weight vs. Gold: ~40% heavier
- Best For: Heirloom and bridal
Platinum's density makes it the most secure setting material for diamonds. The prongs hold their shape and grip over decades of wear in a way softer metals gradually can't match.
Understanding
platinum grades.
Unlike gold, platinum isn't measured in karats. It uses a parts-per-thousand system — Pt950 means 950 parts platinum per 1,000, or 95% pure. The remainder is typically ruthenium or iridium, added for hardness. All three grades are considered fine platinum; the differences are subtle.
Pt850
85.0% PLATINUM
The hardest of the three grades due to a higher alloy content. Less common in fine jewelry but durable. The color reads the same as higher grades — cool, white-grey, and consistent.
Pt900
90.0% PLATINUM
A balance between purity and hardness. Used in a range of fine jewelry and some watch components. Shares the same visual character as Pt950 with slightly more alloy reinforcement.
Pt950
95.0% PLATINUM
The most common grade in fine jewelry. Nearly pure platinum — almost entirely the metal itself, with minimal alloy. The standard for engagement rings and wedding bands where longevity and purity matter most.
Platinum vs.
white gold.
They look similar on the surface. The differences are in what happens over time — and they're meaningful enough to be worth understanding before you choose.
Platinum
The color is the metal.
No rhodium plating. No replating schedule. Platinum's white-grey tone is its natural state and stays that way permanently. It develops a soft patina over years — subtle, and polishable if preferred. The metal itself doesn't diminish with wear; scratches displace rather than remove material, preserving weight and structure over a lifetime.
White Gold
Brightness maintained through care.
White gold achieves its bright finish through rhodium plating — a surface treatment that gradually wears and needs periodic renewal. It's a straightforward service, and white gold remains an excellent choice for many pieces. But for rings worn daily for decades, particularly engagement and wedding rings, platinum's permanence is a meaningful practical advantage.
Caring for
your platinum.
Platinum is the lowest-maintenance precious metal in fine jewelry. It doesn't tarnish, doesn't need replating, and holds its structure indefinitely. A few simple habits keep it looking its best.
01 — Clean
Mild soap. Soft brush.
Warm water and a gentle dish soap handle everyday buildup. A soft-bristled brush reaches around prongs and settings. Rinse thoroughly and dry with a lint-free cloth. No special products needed.
02 — The Patina
It's a feature, not a flaw.
Over time, platinum develops a soft, slightly frosted surface called a patina. Many people find it becomes more beautiful with wear — a lived-in quality that feels personal. If you prefer the original brightness, a professional polish restores it completely.
03 — Store
Separate from other metals.
Even platinum can be scratched by harder materials or stone edges. Store each piece separately in a soft pouch or lined compartment. Platinum's durability is about long-term structure — a little care in storage protects the surface finish.
