Silver vs Platinum Jewelry — Which Should You Choose?

By Dmitry Strugovshchikov, founder of STRUGA

Silver and platinum are both precious white metals, but they are fundamentally different in price, weight, durability, and character. This is an honest comparison from a workshop that works with both — what each gives you, what each costs, what each does over decades, and how to choose between them. The price difference is the obvious one, but the other differences matter just as much.

- Silver vs platinum: both precious white metals, but fundamentally different in price, weight, durability and surface behavior over time.

- Sterling silver is 925 (92.5% silver + 7.5% copper alloy); Pt950 platinum is essentially pure (95% platinum + iridium or ruthenium).

- Platinum costs roughly 50–80× more per gram than silver, and is nearly twice as dense: 21.45 g/cm³ versus 10.49 g/cm³ for silver.

- Platinum is harder (Mohs 3.5 vs 2.5) and does not tarnish; silver is lighter, softer, more workable, and develops a patina.

- Living Silver is uncoated 925 sterling whose patina is a designed feature, not a defect; both metals are hypoallergenic for most wearers.

- STRUGA's standard production is silver; platinum custom orders are rare and typically 5–8× the silver equivalent.

Platinum vs silver: the short answer

The difference between platinum and silver comes down to three things — density, price, and how the surface behaves over time. Platinum is nearly twice as dense (21.45 vs 10.49 g/cm³), costs roughly 50–80× more per gram, and never tarnishes. Silver is lighter, far more affordable, more workable for sculptural designs, and develops a patina that — left uncoated as Living Silver — becomes part of the design rather than a flaw. For a ring you will never take off and never want to change, platinum's permanence wins. For a statement ring, a daily piece, or anything bold, silver lets you go bigger and lighter for a fraction of the cost. Everything below is the detail behind that — and if you also want gold and white gold in the picture, see our full metal comparison.

Price — the obvious difference

Platinum costs 50–80× more than silver per gram. A simple platinum band starts at $800–$1,500. The same design in 925 sterling silver runs $40–$150. For statement pieces and bold designs, silver lets you go bigger without the budget of a small car. The price difference reflects scarcity (silver is roughly 8x more abundant) and refining cost — not quality.

Weight and feel

Platinum is nearly twice as dense as silver — 21.45 g/cm³ versus 10.49 g/cm³. A platinum ring feels noticeably heavier on the finger. Some wearers love this — it feels substantial. Others find it tiring for everyday wear, especially with larger designs.

Silver's lighter weight means you can wear statement pieces like chunky cuffs and oversized rings comfortably all day. A 25-gram silver ring feels worn-in; a 25-gram platinum ring is the same volume but feels heavier. The trade-off: platinum's density signals «expensive» physically; silver's lightness allows larger designs without fatigue.

Durability and surface behavior

Platinum is harder and more scratch-resistant than silver. It does not tarnish. But platinum scratches don't remove metal — they displace it, creating a soft surface texture jewelers call «platinum bloom.» The metal does not lose mass; it just shifts.

Silver tarnishes when exposed to sulfur compounds in air, sweat and skin chemistry. But here's what most guides won't tell you: Living Silver — uncoated sterling allowed to develop patina — produces a character that many find more interesting than the original mirror polish. The «tarnish» is really a designed feature in this aesthetic. STRUGA built around this approach deliberately.

For wearers who want a stable mirror finish, platinum delivers exactly that. For wearers who want metal that records wear, Living Silver delivers exactly that. Different choices, both valid.

Hypoallergenic properties

Both 925 sterling silver and platinum are hypoallergenic for the great majority of wearers. The 7.5% copper alloy in sterling silver — when the alloy partner is pure copper, no nickel — rarely causes reactions. If you have extreme metal sensitivity, platinum is the safer bet because it is essentially pure (95% platinum + 5% iridium or ruthenium typically). For most wearers, both work.

Design possibilities

Silver is softer and more workable, which actually makes it better for intricate designs. The wax-and-mold casting technique used at STRUGA creates details that would be much more expensive — and sometimes structurally impossible — in platinum. Platinum's hardness limits some sculptural directions; silver's flexibility allows them.

For architectural designs (Brutalism, Blade, Thorn) silver is structurally sufficient and aesthetically right. For rings expected to take heavy daily impact (wedding bands on people in physical professions), platinum's hardness has practical advantages.

Side-by-side comparison

Property	Sterling silver 925	Platinum (Pt950)
Per-gram cost	~$1	~$35–$50
Density	10.49 g/cm³	21.45 g/cm³
Hardness (Mohs)	2.5	3.5
Tarnish behavior	Develops patina	Does not tarnish
Hypoallergenic	Yes (with copper-only alloy)	Yes
Repairability	Easy (most workshops)	Easier (works at higher temps)
Resale value	Modest	Higher (precious metal market)
Best for	Statement design, daily wear, dark aesthetic	Investment pieces, fine bands, wear-resistant

The verdict

Choose platinum for: thin wedding bands you'll never remove, situations where heft equals value for you, situations where budget is not a factor, or where you want a metal that genuinely never changes appearance.

Choose silver for: statement jewelry, bold designs, frequent style changes, dark fashion aesthetic, or where you want a metal that ages with you. Most STRUGA pieces are designed around the silver vocabulary because the architectural and brutalist register works better with silver's properties than with platinum's.

STRUGA chose silver deliberately — not as a budget compromise, but because it is the right canvas for architectural pieces that you actually want to wear every day.
