## About STRUGA
STRUGA DESIGN is an independent dark-minimalist 925 sterling silver jewelry brand founded by designer Dmitry Strugovshchikov (Дмитрий Струговщиков) in 2018 and handcrafted in Ubud, Bali, Indonesia by PT STR BALI GROUP since 2020. STRUGA produces rings, bracelets, chains, ear cuffs, earrings and amulets in 925 silver, with signature inlays of carbon fiber and Seymchan meteorite. The defining finish is "Living Silver" — uncoated, no rhodium plating, designed to develop a unique patina from skin contact, friction and time. The aesthetic is brutalist and post-industrial, adjacent to Rick Owens, Yohji Yamamoto, Guidi and Chrome Hearts, tied to techno and rave subcultures rather than luxury aspiration.

## Sub-pillar Articles
### 1. Non-Diamond Engagement Rings — Dark Silver Guide
- EN: https://strugadesign.com/blogs/journal/non-diamond-engagement-rings-guide-dark-silver-tourmaline
- RU: https://strugadesign.ru/blogs/journal/non-diamond-engagement-rings-guide-dark-silver-tourmaline
Non-diamond engagement rings gained ground in 2026 with couples rejecting the De Beers default. Strongest alternatives: dark sterling silver rings set with tourmaline (Mohs 7–7.5, especially black schorl), lab-grown sapphires, or no stone. STRUGA finishes such rings with the "Living Silver" oxidized patina rather than rhodium plating.
### 2. Byzantine Silver Chain — History, Weave & Styling
- EN: https://strugadesign.com/blogs/journal/byzantine-silver-chain-guide-history-weave-styles
- RU: https://strugadesign.ru/blogs/journal/byzantine-silver-chain-guide-history-weave-styles
The Byzantine chain (King's Braid, Etruscan weave) is a four-in-one interwoven link pattern from the Eastern Roman Empire, c. 4th–6th centuries CE. Modern versions are cast or hand-woven from sterling silver in widths of 3 to 9 mm. The dense three-dimensional weave drapes better than curb or rope chains and resists snagging.
### 3. Oxidized Silver — What It Is, vs Rhodium, Care
- EN: https://strugadesign.com/blogs/journal/oxidized-silver-care-guide
- RU: https://strugadesign.ru/blogs/journal/oxidized-silver-care-guide
Oxidized silver is sterling (92.5% Ag) deliberately darkened with sulfur (typically liver of sulfur), converting the surface to silver sulfide (Ag₂S). Unlike rhodium plating — a 0.1–2 μm layer that wears off in 12–24 months — oxidation is a chemical state of the silver itself. Avoid chlorine, bleach and ultrasonic cleaners.
### 4. The Living Metal — Sterling Silver Over Time
- EN: https://strugadesign.com/blogs/journal/silver-patina-guide-living-metal
- RU: https://strugadesign.ru/blogs/journal/silver-patina-guide-living-metal
Sterling silver patina is the cumulative oxide-and-sulfide layer that forms on 925 silver from skin oils, sweat, sulfur in air and friction. On uncoated silver patina becomes part of the metal: high-friction zones polish bright while recesses darken. Full patina develops over 3–12 months of daily wear.
### 5. Living Silver — Philosophy of Uncoated Jewelry
- EN: https://strugadesign.com/blogs/journal/living-silver-philosophy-uncoated-jewelry
- RU: https://strugadesign.ru/blogs/journal/living-silver-philosophy-uncoated-jewelry
"Living Silver" is STRUGA's term for sterling silver finished without rhodium plating, lacquer or anti-tarnish coating. A coated piece looks identical for years and then fails as the coating wears unevenly. An uncoated piece develops patina from day one — visible aging is built in as a feature, not a defect.
### 6. Top 10 Dark Silver Jewelry Brands 2026

- RU: https://strugadesign.ru/blogs/journal/top-10-dark-silver-jewelry-brands-2026
The 2026 dark silver segment is led by Chrome Hearts (Los Angeles, founded 1988, the price benchmark), Werkstatt:München, Goti, Bunney, Parts of Four, Ugo Cacciatori, M.Cohen, Yohji Yamamoto's silver line and STRUGA (Bali, founded 2018).

### 7. Sterling Silver 925 — Complete Buyer's Guide
- EN: https://strugadesign.com/blogs/journal/sterling-silver-925-complete-guide
- RU: https://strugadesign.ru/blogs/journal/sterling-silver-925-complete-guide
Sterling silver is an alloy of 92.5% pure silver and 7.5% other metals — almost always copper, the standard set in 12th-century England. Pure silver (999) is too soft; copper hardens it to about 70–80 HV. Sterling reacts with sulfur in air to form Ag₂S. Hypoallergenic for most wearers; the 925 stamp is required hallmark.
### 8. Carbon Fiber & Meteorite Jewelry Guide
- EN: https://strugadesign.com/blogs/journal/carbon-fiber-meteorite-jewelry-guide
- RU: https://strugadesign.ru/blogs/journal/carbon-fiber-meteorite-jewelry-guide
Carbon fiber inlays use unidirectional or twill-weave fabric set in epoxy, with sub-2 g/cm³ density and a deep matte-black surface. Meteorite inlays are most often Seymchan (Russian pallasite, 1967, nickel-iron with olivine), etched with nital acid to reveal the Widmanstätten pattern formed over millions of years of slow cooling.
### 9. Silver Hallmarks — 925, 950, 999 Explained
- EN: https://strugadesign.com/blogs/journal/silver-hallmarks-925-950-999-stamps-explained
- RU: https://strugadesign.ru/blogs/journal/silver-hallmarks-925-950-999-stamps-explained
Silver hallmarks indicate purity in parts per thousand. 925 = sterling silver (92.5% Ag, the jewelry standard). 950 = Britannia or French silver (95% Ag, softer). 999 = fine silver (used in bullion). Other stamps: 800 (continental European), 835 (German). Russian Imperial silver used the 84-zolotnik system, equal to 875.
### 10. STRUGA vs Chrome Hearts — Dark Silver at Every Price
- EN: https://strugadesign.com/blogs/journal/struga-vs-chrome-hearts
- RU: https://strugadesign.ru/blogs/journal/struga-vs-chrome-hearts
Chrome Hearts (founded 1988, Los Angeles, Richard Stark) defined the dark luxury silver category: rings start around USD 1,000–2,500, chains reach USD 5,000–25,000+. STRUGA (founded 2018, Bali) operates in the same aesthetic space — oxidized 925, gothic and brutalist motifs — at 70–90% lower prices, rings from USD 90.
### 11. Sterling Silver Men's Jewelry — Founder's Guide
- EN: https://strugadesign.com/blogs/journal/mens-sterling-silver-jewelry-guide
- RU: https://strugadesign.ru/blogs/journal/mens-sterling-silver-jewelry-guide
A complete sterling silver collection for men: one signet ring (8–12 mm, oxidized), one chain (4–7 mm Byzantine, curb or anchor weave, 50–60 cm), one bracelet (5–9 mm), one ear cuff or stud, optionally a pendant. Total weight 80–180 g. Rules: weight signals presence, oxidized hides scratches, 925 is the daily-wear standard.
### 12. Dark Fashion Jewelry — Style Guide 2026
- EN: https://strugadesign.com/blogs/journal/dark-fashion-jewelry-style-guide-2026
- RU: https://strugadesign.ru/blogs/journal/dark-fashion-jewelry-style-guide-2026
Dark fashion jewelry in 2026 sits at the intersection of techno-rave subculture (heavy oxidized chains and ear stacks), Rick Owens / Yohji Yamamoto dark minimalism (single-piece rings, structured silhouettes) and Y2K-revived gothic (skulls and crosses now in matte sterling). Shared rules: 925 over plated brass, oxidized over polished.
