Facettierte

Facettierte is the German adjective meaning “faceted” and is the past participle of the verb facettieren, which means to facet or cut into flat faces. The related noun Facette refers to a single facet or to the concept of facetting. The term is commonly used in gemology, mineralogy, and design to describe surfaces that have been divided into multiple flat faces.

In jewelry and gemstone cutting, faceting is a key technique used to enhance light performance. Facets are arranged in patterns tailored to the gemstone’s shape and optical properties, with the goal of maximizing brilliance, dispersion, and scintillation. A gem described as facettiert or facettierted is one that has been cut to reveal many flat surfaces, as opposed to a smooth, uncut crystal or a cabochon.

The process is subtractive and requires precision in angle, symmetry, and polish. Incorrect angles or uneven facets can reduce brightness or cause light leakage. Modern faceting often employs computer-assisted tools or precision hand machinery, but the basic objective remains the same: to control how light enters, reflects inside, and exits the gem.

Beyond gemstones, facetted surfaces are also used in glass, ceramics, and architectural design to create visual texture, improve glare control, or emphasize geometric aesthetics. In these contexts, facettierte surfaces may be produced for functional reasons (such as light diffusion) or for decorative effect.

In German-language usage, terms such as facettiert or facettierte Oberflächen are common, and the concept is widely understood across jewelry, optics, and design fields.
