Lost-Lace Cast Silver and Bronze Jewelry

Joyería con Encaje Fundido

Casting real lace directly into silver, so that a ring or cuff carries the exact negative impression of the textile: an openwork, web-like relief that carving or stamping cannot reproduce. The documented practitioner, Adriana Guelfi Herera, also works in bronze, gold plating, leather, wool and semiprecious and native stones, mostly as unique pieces, aiming to 'traducir la magia de los ciclos de la Naturaleza' (translate the magic of nature's cycles); she packages her work in fabric printed with natural dyes and boxes of native Uruguayan wood.

Geographic Center
Not specifically detailed beyond general Uruguay in available sources; flagged for follow-up direct documentation of the workshop's physical location
Community / Ethnic Group
Uruguayan contemporary jewelry-artisan community
Estimated Origin
Not specifically dated in available sources beyond Guelfi's own individually developed practice; flagged for follow-up
Cultural Function
Guelfi explicitly frames each piece as arising from 'una búsqueda consciente e interactiva dentro de la Naturaleza' (a conscious, interactive search within Nature), positioning her jewelry as 'un legado fiel de la Naturaleza' (a faithful legacy of Nature) rather than purely decorative object-making
Primary Materials
Silver 925, bronze, gold plating (baño de oro), worked using a technique that casts real lace textile directly into metal
Primary Tools
Standard investment-casting equipment, adapted specifically for lace-textile lost-pattern casting
Process Overview
Genuine lace textile is prepared and invested for casting, then burned away in a process analogous to lost-wax casting, leaving silver, bronze, or gold-plated metal cast in the exact negative impression of the original lace's threads and openwork pattern; Adriana Guelfi Herera produces predominantly one-of-a-kind rings and cuffs using this lost-lace casting technique, alongside pieces incorporating leather, wool, and semiprecious and native stones, framing her practice as a conscious translation of natural cycles into wearable form, extended through handmade, naturally-processed packaging.
Traditional Applications
Not specifically documented as tied to a prior inherited tradition; Guelfi's practice is documented as an individually developed contemporary artisanal career
Contemporary Applications
Collectible fine jewelry (rings, cuffs, earrings) sold as predominantly one-of-a-kind pieces
Notable Practitioners
Adriana Guelfi Herera, jewelry artist, working under her own name
