Blackened Silver — the dark side of STRUGA
The first thing you notice in a STRUGA piece is the colour. Not the bright shine of classic silver, but a deep, dark tone — as if the metal had passed through time and earned its history. This is the blackened finish — oxidised silver, the visual signature of the brand.
What blackened silver is
Blackening (oxidation) is a controlled chemical process on the surface of 925 sterling silver. Under specific compounds the silver takes on a dark, almost black tone. It is not a coating, not a paint — it is a chemical change in the metal's outer layer.
Unlike rhodium plating or galvanic finishes, oxidised silver lives and changes over time. Raised surfaces gradually lighten through skin contact, building a natural contrast between dark recesses and bright edges. We call this process Living Silver — a philosophy in which the piece is not a static object but evolves with its wearer.
Blackened versus plain silver
Standard silver chases brightness — it is polished, plated, defended against tarnish. STRUGA goes the other way: we deliberately build a dark surface and accept its natural evolution.
The blackened finish exposes texture and relief. Where polished silver smooths detail under its shine, blackened silver lays bare every edge, every thorn, every irregularity. That is why this approach belongs to STRUGA's brutalist, minimalist language.
The patina philosophy
The Japanese tradition has a concept — wabi-sabi, the beauty of imperfection and the marks of time. STRUGA's philosophy meets it halfway: we do not fight patina, we welcome it. Every scratch, every shift in tone is not a flaw but part of the piece's story.

The Blackened collection
The blackened finish runs through every STRUGA line, but it is most fully expressed in the RITUAL Blackened collection. Here dark silver meets raw stones and organic forms — objects on the edge between jewelry and artefact.
If you want a piece with a specific depth of blackening or a particular character of patina, send a request through the order form. We will build the object to your vision.
How blackened silver gets its color
Blackened silver is silver that has been treated with a sulfur-based solution to chemically darken the surface. The active layer is silver sulfide (Ag₂S), the same compound that forms naturally as tarnish — applied deliberately, with control over depth and uniformity, as a design choice rather than a defect.
The treatment is typically liver of sulfur (potassium polysulfide) or proprietary darkening solutions. The artisan immerses or paints the solution onto the piece, watches the surface darken to the intended depth, and then selectively removes the darkening from raised surfaces with fine abrasives. The result: dark recesses with bright highlights — the dramatic light-shadow contrast that defines the aesthetic.
The technical depth of blackened silver
- The dark layer is real silver chemistry. Silver sulfide is structurally part of the metal surface, not a coating sitting on top.
- Depth is controllable. Light treatment produces grey; longer treatment produces near-black. Different artisans calibrate the depth based on the design intent.
- The treatment doesn't seal the metal. Below the blackened layer, the underlying silver is still real 925. Repair and refinishing are possible.
- Selective removal creates contrast. The artisan polishes raised surfaces back to bright while leaving recessed areas dark. This is sculpture, not just chemistry.
- Each piece's blackening is unique. The same design treated by different artisans, or by the same artisan on different days, produces subtly different results. Variation is part of the character.
How blackened silver ages with wear
Over time, the blackened surface interacts with skin contact and ambient conditions:
- Contact points brighten. Where skin touches the silver regularly — knuckles on rings, contact areas on bracelets — friction wears through the surface darkening over months and exposes the brighter metal beneath.
- Recesses stay dark. Areas that don't contact skin retain their darkening almost indefinitely.
- The pattern is unique to the wearer. Two identical blackened pieces will look different after six months on different wearers.
- Re-blackening is possible. If the contrast fades too far, the piece can be sent back for re-application. STRUGA offers this as part of lifetime refinishing.
STRUGA's specific approach
STRUGA uses both intentional blackening (the Blackened Silver collection) and natural Living Silver patina (most other pieces). The choice is design-led: pieces where the design intent is dramatic light-shadow contrast get intentional blackening; pieces where the design intent is gradual character development get Living Silver.
The technical approach is consistent across both. The 925 sterling alloy is the same. The hand finishing is the same. Only the surface treatment differs. A buyer who wants to switch a Living Silver piece to blackened, or vice versa, can have it done — both directions are possible through the workshop.
Care for blackened silver
- Gentle cleaning only. Aggressive polishing removes the darkening from intentionally darkened recessed areas.
- No silver-dip solutions. Commercial silver dips strip all darkening — designed for bright pieces only. Will permanently remove intentional blackening.
- Selective polishing only. Use a polishing cloth on the highlighted bright areas if you want to refresh contrast, but never on the recessed dark areas.
- Re-application possible. If the darkness fades unevenly, any competent silversmith can re-apply liver of sulfur to restore the original character.
- Avoid pool water and salt water. Chlorine and salt accelerate uneven wear on blackened surfaces.
Frequently asked questions
Is blackened silver different from oxidized silver?
Same fundamental process — chemical darkening with sulfur compounds. «Blackened» usually implies darker, more dramatic treatment; «oxidized» can refer to milder treatment. The terms are often used interchangeably.
Will the blackening rub off?
Yes, gradually, on contact points. This is the design — high-contact areas brighten while recesses stay dark. The piece does not «lose» its blackening; it gains a wear pattern.
Is blackened silver safe for skin?
Yes. Silver sulfide is hypoallergenic and structurally part of the silver. STRUGA's nickel-free 925 alloy is safe regardless of finish.
Can blackened silver be polished back to bright?
Yes. Aggressive polishing or silver dip removes the blackening completely, revealing the bright silver underneath. This destroys the design intent of the piece, so it's a last resort, not a routine cleaning method.
Why does my blackened ring look different from the photo?
Two reasons. First, photographs are taken at a specific point in the piece's life; your piece may be at a different stage. Second, blackening varies slightly between pieces because each is treated by hand. Both are intended.
Can I have a Living Silver piece blackened?
Yes through the workshop. The treatment can be applied retroactively. STRUGA offers this as part of lifetime service.
Is blackened silver more allergenic than bright silver?
No. The blackened layer is silver sulfide — same skin compatibility as untreated 925. STRUGA's alloy is nickel-free regardless of finish.
About STRUGA. STRUGA is a dark silver jewelry brand founded by Dmitry Strugovshchikov and Ekaterina Strugovshchikova, handcrafted with Balinese and international silversmiths. Every piece is 925 sterling silver, naturally oxidized or hand-patinated. The darkening is part of the design. It is a brutalist object that reacts and changes through contact with the environment and the wearer.
