Centro De Joalharia De Lisboa

What Centro De Joalharia De Lisboa does

Centro de Joalharia de Lisboa (CJLX) is a Lisbon-based, DGERT-certified jewellery training school founded in 2012 that delivers professional, hobby, and experiential education across traditional and contemporary jewellery-making techniques. The school operates from a fully equipped atelier at Rua João Saraiva, 28 rch in Lisbon and extends to a partnership site in Albufeira (Algarve) with Atelier Mariana Mateus, with 1–10 employees. Its core offering spans a 900-hour Alta Joalharia professional program (€8,000–8,600), a 3-month Jewellery Making Foundations course (€3,200–3,350), short specializations such as micro-cravação, Portuguese filigree, creative wax modelling and jewellery illustration (€525–2,700), and single-session experiences including wedding ring workshops and Alquimia do Ouro/Prata (€140–350 per person). Curriculum integrates traditional bench techniques (sawing, filing, soldering, casting, micro stone-setting under microscope and electric graver) with digital tools via an official RhinoArtisan CAD partnership, and is taught by instructors with luxury-brand credentials including master stone-setter André de Carvalho (Rosior, Chopard, De Grisogono, Cartier).

The business model combines five revenue streams: recurring professional training tuition with installment plans, one-time specialization and short-course fees, single-session workshops and experiences (also sold via gift vouchers through an e-commerce storefront), monthly Alumni (39€/4 weeks, 12-month minimum) and Open (59€/4 weeks) bench-rental subscriptions for alumni and external practitioners, and professional services such as prototyping, casting in gold (9k–19.2k), silver 925, brass, and bronze, plus stone-setting and restoration. Customer segments span aspiring professional jewellers (primary), hobbyists, couples seeking personalized wedding rings, working industry professionals requiring specialized training or B2B services, and international students recruited through English-language delivery and visa support. Distribution is direct via the two physical locations plus online booking through Acuity Scheduling; marketing relies on the cjlx.pt website, Instagram and Facebook presence, email newsletters, in-person informational meetings, and earned recognition including four consecutive Casamentos.pt Wedding Awards (2022–2025). Documented alumni outcomes include placements at Bvlgari and Louis Vuitton, with a mentorship program supporting graduate business creation.

Scale indicators5 records

Recent moves7 records

Expansion highlights5 records

Broad incumbents

• École Boulle: A prestigious Parisian public school offering jewellery design and crafts programs at scale. Comparable to CJLX as a French/EU benchmark for trade-school jewellery training, though broader in scope and significantly larger in headcount.
• Gemological Institute of America (GIA): The world's largest gemology and jewellery education institution. While broader in scope (covering gemology, grading, and design), GIA offers comparable professional certificates and online/blended learning that competes with CJLX's internationally portable credentials.
• International Gemological Institute (IGI): A global diamond and gemstone grading school with internationally recognised certification. Comparable to CJLX in targeting professional career-changers and offering internationally portable credentials, though IGI's focus is on gemology rather than bench jewellery making.

Emerging players

• Reena Ahluwalia Design & Education: An independent jewellery master and educator offering premium courses, masterclasses, and digital design tools. Comparable to CJLX's high-end master-craftsman positioning and integrates digital design (CAD) into instruction.
• Jewelry Making Daily (Interweave): An online jewellery education content platform offering tutorials, videos, and live workshops. Competes with CJLX's hobbyist and short-course tiers at lower price points, but lacks bench access and certified credentials.
• USHARYA Design & Crafting School: A Mumbai-based jewellery making school offering certified professional and hobby courses. Comparable to CJLX in tiered offerings (professional + hobby), though operating in a much larger and lower-cost market.

Direct peers

• Van Vliet Siemonsma Vakopleiding Juwelen: A Dutch jewellery trade school offering multi-year professional training and specialisations in techniques including stone-setting. Closely matches CJLX's Alta Joalharia-equivalent curriculum and European regulatory certification model.
• British Academy of Jewellery: A London-based jewellery trade school offering professional diplomas, intensive courses, and short workshops. Directly comparable to CJLX in offering tiered professional and hobbyist jewellery training with bench-based instruction, alumni placement, and master craftsman instructors.
• Holts Academy of Jewellery: A long-established UK jewellery school providing accredited professional training and short courses, similar to CJLX's DGERT-certified programs. Both compete for aspiring jewellers seeking intensive, full-time bench training in a dedicated atelier environment.

Regional players

• Studio Ingot: An Australian jewellery school offering professional diplomas, workshops, and bench hire. Directly comparable in offering a tiered professional-to-hobby curriculum plus alumna-focused bench rental, but operates in a different geography (Oceania).
