The intersection of industrial engineering and artisanal craft in the Netherlands reached a defining moment in 1944 with the publication of Goud, Zilver en Edelstenen (Gold, Silver, and Gemstones) by Engineer Johannes (J.) Hammes. This work stands not merely as a textbook, but as a monumental archive of technical knowledge, historical context, and professional standards for the jewelry and precious metals industry during a period of significant global upheaval. Commissioned by the Federation for Gold and Silver, the book was designed to address a critical void in Dutch vocational literature. It serves as a definitive guide for goldsmiths, silversmiths, and jewelers, bridging the gap between raw material science and the practical application of craftsmanship.
The publication of this text occurred during the Second World War, a time when the Dutch jewelry industry faced immense challenges. Despite the wartime economy, the Federation recognized the urgent need for standardized, high-quality educational material. Hammes, an industrial engineer at the prominent firm Gerritsen & Van Kempen, was uniquely positioned to author this work. His dual background in engineering and the precious metals trade allowed him to synthesize technical precision with artisanal nuance. The result was a comprehensive handbook that has transcended its era, remaining a vital resource for historians, gemologists, and practitioners of esoteric and spiritual disciplines who seek to understand the material culture of the period.
The Author and the Industrial Context
Johannes Hammes (1892–1962) was not a traditional artisan but a bedrijfsingenieur (corporate engineer) employed by Gerritsen & Van Kempen, a leading enterprise in the gold and silver industry. This professional background is central to understanding the tone and scope of the book. Unlike earlier craft manuals written by individual artisans, Hammes approached the subject with the rigor of an engineer. He was tasked with creating a learning book for students of silversmithing and jewelry making, but the scope expanded to cover the entire spectrum of precious metals and gemstones.
The context of the authorship is deeply intertwined with the leadership of the industry. A.E. van Kempen (1893–1970), who served as the chairman of the Federation for Gold and Silver, was also the director of Gerritsen & Van Kempen. This connection highlights the strategic nature of the project. The Federation, previously known as the "Federation for the Protection of the Interests of the Trade in Gold and Silver Works," sought to professionalize the trade. The introduction to the book explicitly states that the dissemination of sound technical knowledge was severely hindered by the scarcity of individuals willing to share their experience through writing. Hammes was the chosen vessel to fill this void.
The timing of the book's creation is particularly significant. Written and published in 1944, the work emerged during the occupation of the Netherlands. The scarcity of Dutch vocational literature in this field prior to the war made this publication a critical intervention. It was not merely a collection of tips and tricks but a systematic compilation of the industry's collective knowledge. The fact that the book was commissioned by a federation representing the industry's interests underscores its authority. It was intended to serve as a standard reference for the training of future craftsmen, ensuring that the skills of goldsmithing and gemology were preserved and standardized despite the chaotic external environment.
Physical Characteristics and Publication Details
The physical manifestation of Goud, Zilver en Edelstenen is as impressive as its content. Published by De Technische Boekhandel H. Stam in Amsterdam, the book was released in 1944. It is a substantial volume, containing 602 pages of dense, illustrated text. The physical construction of the book reflects the high value placed on the material. It features a cloth-bound hardcover (linnen band), with a fore-edge and back-edge gilding (top edge guilt), indicating a luxury or special edition feel even in the austerity of wartime.
The publication details reveal the economic reality of the time. The standard cloth-bound edition was priced at ƒ 27.50, while the luxury edition cost ƒ 50. In the context of 1944, these were significant sums, reflecting the book's status as a high-quality, essential acquisition for professionals. The book includes numerous illustrations, both in color and black-and-white, which serve to clarify complex technical procedures and gemological characteristics.
The book is currently a rarity, especially in good condition. The Stichting De ZilverKamer Zeist, a foundation dedicated to collecting silver, silver-plated, and tin objects from Zeist's factories, holds both the first and second editions of the work in their collection. This institutional preservation underscores the book's status as a historical artifact. On the secondary market, such as Marktplaats, copies are listed as rare items. While some pocket-sized or abridged versions (like the "Phoenix Pockets" edition) exist as cheaper alternatives, the full 602-page volume remains the definitive edition.

Technical Scope and Pedagogical Value
The primary function of Hammes' work was to serve as a comprehensive handbook for the craft of goldsmithing and gemology. The book details techniques, processing methods, and background information regarding precious metals and stones. It covers the entire workflow, from the raw material to the finished piece. This technical depth distinguishes it from general encyclopedias. It was written specifically for apprentices and professionals in training, aiming to standardize the knowledge base of the industry.
The content is structured to provide a "thorough knowledge transfer" (grondige kennisoverdracht). It does not simply list facts but explains the mechanisms of working with gold, silver, and gemstones. This includes the metallurgical properties of the metals, the cutting and setting techniques, and the identification of gemstones. The book acts as a bridge between the scientific understanding of materials and the artistic application in jewelry making.
For the modern reader, the book offers a historical snapshot of the technologies and trends of the 1940s. It documents the state of the industry at a specific moment in time, capturing methods that may have since evolved or been replaced. However, the fundamental principles of gemology and metalworking remain valid, making the text a living document for those studying the history of the craft.
Recognition and Legacy
The significance of Hammes' contribution was formally recognized by the industry body that commissioned it. For this magnum opus, Johannes Hammes was awarded the Silver Medal of Honor (zilveren erepenning) from the Federation for Gold and Silver. This award was not merely ceremonial; it signified that the book met the highest standards of technical accuracy and pedagogical value. It validated the work as an essential text for the profession.
The legacy of the book extends beyond the immediate needs of the 1940s. Today, it is considered a rare collector's item. The scarcity of the book in the current market, with listings appearing sporadically on platforms like Marktplaats, attests to its status as a sought-after historical document. The fact that the Stichting De ZilverKamer Zeist has preserved both editions highlights its importance in the cultural heritage of the Dutch jewelry industry.
Furthermore, the book has found a new audience in the realms of spirituality and esotericism. While originally a technical manual, its detailed descriptions of gemstones and their properties have made it a valuable resource for those interested in the metaphysical aspects of stones. The historical context provided by Hammes offers a unique perspective on how gemstones were understood and utilized in the mid-20th century, providing a foundation for modern esoteric practices. The book is now seen as an essential reading for anyone exploring the intersection of material science and spiritual belief.
The Historical Void and the Federation's Role
Before the publication of Hammes' book, there was a distinct lack of Dutch vocational literature in the field of goldsmithing and gemology. The introduction of the book, written by the Federation's board, explicitly notes that the spread of sound technical knowledge was hindered by the small number of people willing to disseminate their knowledge through writing. This "void" created a barrier to professional development.
The Federation for Gold and Silver (Federatie Goud en Zilver) was the driving force behind this publication. Originally named the "Federation for the Protection of the Interests of the Trade in Gold and Silver Works," this body acted as a central hub for the industry. By commissioning Hammes, they sought to create a standardized curriculum for apprentices and a reference for established craftsmen. The involvement of the Federation ensures that the content was vetted and aligned with the industry's needs.
The collaboration between Hammes and the Federation was strategic. The chairman of the Federation, A.E. van Kempen, was also the director of Hammes' employer, Gerritsen & Van Kempen. This overlap of professional and organizational leadership ensured that the book would be relevant to the actual working conditions of the trade. It was not an academic exercise but a practical tool for the industry.
Availability and Market Presence
In the contemporary market, Goud, Zilver en Edelstenen is a rare find. The book is primarily available through the second-hand market. Listings on platforms like Marktplaats show a range of conditions and prices. While the full 602-page edition is the most valuable, there are also smaller, pocket-sized versions (such as the "Phoenix Pockets" edition) that serve as more accessible introductions.
The price variation in the market reflects the book's condition and rarity. A standard used copy might be listed for a nominal fee (e.g., €3.00 for a pocket version), while a pristine, first or second edition hardcover can command a significant price (e.g., €75.00). The Stichting De ZilverKamer Zeist serves as a custodian of these works, holding both the first and second editions in their permanent collection. This institutional preservation ensures that the knowledge contained within the book remains accessible to researchers and historians.
The scarcity of the book has elevated it to the status of a collector's item. For those interested in the history of the Dutch jewelry trade, possessing a copy of Hammes' work is a significant acquisition. The book represents a specific moment in time—the 1944 edition—capturing the state of the industry during the war. Its presence in the market is sporadic, making each listing a notable event for collectors and enthusiasts.
Synthesis of Craft, Science, and Spirituality
Hammes' work transcends the boundaries of a simple technical manual. It serves as a nexus where the hard science of metallurgy and gemology meets the art of craftsmanship and, increasingly, the realm of spiritual practice. The detailed descriptions of gemstones and the technical methods of working with gold and silver provide a factual foundation that supports both the artisan and the spiritual seeker.
For the modern reader interested in esotericism, the book offers a historical lens through which to view the properties of gemstones. The "technical view" provided by Hammes grounds spiritual practices in the physical reality of the materials. This duality makes the book a unique resource for those who wish to understand the material culture of the 1940s while exploring the metaphysical significance of stones. The book's endurance as a relevant text for both professionals and spiritual practitioners demonstrates its comprehensive nature.
The synthesis of these elements—technical precision, historical context, and cultural significance—makes Goud, Zilver en Edelstenen a timeless document. It is a testament to the dedication of Johannes Hammes and the vision of the Federation for Gold and Silver to preserve and disseminate the knowledge of the trade.
