Design Concept The Core signet is the fundamental pillar of the Black Rock aesthetic. Hand-sculpted in our Copenhagen atelier, this piece is a visceral tribute to the raw power of the earth. Its surface is characterized by a signature "Rock" texture—deeply eroded, organic, and unapologetically brutalist. This isn't just a ring; it's the core identity of the brand, designed for those who seek a direct connection to the primal elements of nature.

Material & Craft

Material: Heavyweight Solid 925 Sterling Silver, 100% recycled (Hallmarked).
Process: Individually hand-carved "Raw Rock" texture, traditional lost-wax casting.
Finish: Signature satin-brushed matte silver with deep oxidation in the recessed craters to enhance the volcanic relief.
Origin: Locally handmade to order in Denmark.

Artisan Note Each Core signet is an individual sculpture. Because the texture is hand-sculpted without a fixed mold, the specific landscape of ridges and valleys is unique to your piece. This ensures that your ring is a one-of-a-kind relic, a fragment of silver that tells its own geological story.

Service

Shipping: Free, fully insured delivery within the EU (Free EU Shipping). Shipping costs outside the EU are shown at checkout. Import duties or local taxes may apply for orders shipped outside the EU.
Lead Time: Hand-crafted to order. Please allow 8-15 business days for production.
Quality: Solid silver construction (non-hollow) for a substantial, premium feel that lasts a lifetime.

Made-to-Order Policy Each CORE piece is handcrafted to your specifications and is therefore exempt from the EU 14-day right of withdrawal pursuant to Article 16(c) of Directive 2011/83/EU (goods made to the consumer's specifications). This exemption does not affect your statutory rights in the event of defects or non-conformity. If your piece has a defect or does not match your order, we will remake or refund it without question — contact us at vincent@blackrockjewel.com
