Metals & Gemstones

Quality is our utmost priority. We meticulously source quality gemstones from around the globe for our collection. Our craftsmen bring your designs to life with precision and beauty, blending traditional techniques with modern innovation. Every piece undergoes stringent quality checks, ensuring it meets our exacting standards.

Metals

Fine gold is chemically pure gold. It is free of all other metals such as copper and silver and can be rolled out into a gold leaf (approx. 1 micrometer). Fine gold is light yellow in colour and does not change when exposed to air. Fine gold is the most ductile metal, hence it is alloyed with other metals during processing. White gold is created through alloying pure gold with white metals such as palladium and silver. The soft pink complexion of rose gold is created through the inclusion of copper.

Carat

Composition

14 carat gold

About 58.5% fine gold + 41.5% other metals

Surfaces

Sand-blasted/Sand-matt

A strong matte finish is achieved with a sandblasting machine that rotates rings while blasting them with fine sand or quartz. The finish is smoother with finer sand and rougher with coarser sand.

Polished

This method involves using a series of carefully selected abrasives to achieve a smooth and lustrous surface.

Matt/Silk-matt

Whereas a surface smoothed by sanding becomes shiny when polished, matting roughens the surface, making it appear dull and matte. Depending on the method used, the matte finish can be more or less fine-grained.

Hammer

This surface treatment is often lovingly carried out by hand and involves hammering many small round indentations into the ring with the rounded surface of an engraving hammer. Rings with a surface such as this are usually found in polished condition. Hammer finishing serves as an extraordinary decorative element.

Ice-matt

For the “ice-matt” finish, jewellery is treated with diamond files, a diamond pad, or coarse sandpaper in circular motions. This creates visible scratches that, when paired with polished surfaces or sparkling gemstones, add a unique charm.

Transverse matt/Longitudinal matt/45° sloping matt

With this surface refinement, jewellery is given its unique texture using an abrasive fiber fleece, a matting brush, or a machine. Transverse matting creates short vertical lines, longitudinal matting creates long horizontal lines, and 45° oblique matting creates angled lines that can be aligned to the left or right.
