Mineralgarvning

Mineralgravning, or mineral engraving, is the practice of inscribing or carving onto mineral specimens and related materials. It is used in museology, jewelry, and mineral collecting to label objects, record information, or create decorative motifs. The field covers both traditional hand engraving and modern techniques, with attention to preserving the integrity of the specimen.

Techniques and materials vary by hardness and structure of the substrate. Common tools include diamond-tipped burs, carbide gravers, micro-drills, and laser engraving systems for higher precision. Substrates typically include hard minerals such as quartz, agate, jasper, marble, and other durable stones, as well as glassy minerals and, in some cases, synthetic materials used in decorative pieces. The choice of technique balances detail, depth of cut, and risk of cracking or chipping.

History and use: Engraving on stone and mineral surfaces is part of the broader tradition of lapidary arts and artifact decoration. In modern contexts, mineralgravning is employed in museums for labeling specimens, in the gem trade for maker’s marks or serial identifiers, and in artistic circuits for inscriptions on mineral-based media. It can range from small, discreet marks to elaborate pictorial or script work.

Considerations and safety: Engraving can alter the surface and, in brittle specimens, potentially affect value or structural integrity. Practitioners often test on inconspicuous areas and document modifications. Protective measures include dust control, appropriate PPE, and, where necessary, stabilization of delicate pieces before work.
