Andeer – natural green quartzite

Andeer is a historic, sober, and highly prized natural green quartzite mined in the Val Schams region, near the municipality of Andeer in the canton of Graubünden, Switzerland. Highly appreciated in Alpine and contemporary architecture, interior design and large landscape works for its discreet natural charm and exceptional structural durability, it represents a reference material for the Swiss stone tradition.

Visually, it is distinguished by an elegant and homogeneous background matrix in shades of light emerald green, sage green, grey-green and mint green, capillarily enriched by thin flamed layers, streaks and micaceous textures oriented in shades of silver grey, quartz white and graphite black.

Technical characteristics of the Andeer

Geologically, it is a metamorphic orthogneiss/quartzite with a predominantly silicate composition (rich in quartz, potassium feldspars, plagioclase and micas such as muscovite and phengite which give it its characteristic green colour). As a strictly silicate matrix material with no carbonate components, it does not react to food or household acids (such as lemon, vinegar, wine, juices or common detergents) and is not subject to acid attack opacification. It has a very high hardness (Mohs scale 6–7), exceptional resistance to abrasion, scratches, intense trampling, thermal changes and frost (total frostiness), combined with an extremely low liquid absorption rate.

Applications in design

– luxury kitchen tops and countertops: an excellent choice for kitchen tops, scenic islands, and bar counters thanks to their absolute immunity to food acids, scratches, and high temperatures.

– high-traffic flooring and cladding: perfect for interior and exterior floors, executive lobbies, plazas, walkways, stairways, and ventilated facades thanks to its total frostiness and mechanical resistance.

– bathroom, SPA, and wellness areas: ideal for bathroom upholstery, shower trays, vanity tops, pools, and SPA edging, where sage-green hues evoke harmony and natural balance.

– architectural and landscape design elements: widely used for covers, pool edges, curbs, fireplace surrounds, custom tables, and high-end street furniture.
