Silestone worktops, like those of other quartz brands, are made up of 90-95% quartz and other hard glass, mineral or metallic materials etc. The other 5-10% is composed of polyester resin, a kind of plastic. Cosentino of Spain, the maker of Silestone, is one of the oldest companies in the field. Innovators in design and technological development, Silestone has made this family-run company an multinational presence with plants in many countries in a quarter of a century. We have visited Cosentino HQ in Almeria on several occasions, taking with us representatives our kitchen company clients. See our reports here and here.

Silestone has a number of advantages, among them:

• an on-going commitment to the use of recycled material – in the old and now discontinued ECO brand and now in the newer Loft materials
• materials at the forefront of design innovation
• a 25 year guarantee (your worktops purchase needs to be registered with Silestone

Study in black and white – undermount sinks in Blanco and Negro Stellar

Grainy and sandy coloured – incredibly practical, easy to live with and excellent value for money!

The grey equivalent to Blanco City – liveable, economical, durable

Darker grey than Gris Expo, and not quite as easy to live with, but an economical choice if you need a darker option.

Dark grey with a slightly “clumpy” texture in the pattern

Beautiful, large-grained, warm white. Bright and practical with no bling element

Cemento Spa is THE smooth darker grey from Silestone, just at the sweet spot between reasonable price, smoother granulation and great surface quality.

Natural textured pattern in a warm greige; good looking and punches above its weight on price

Warm chocolate brown with a good marbling which makes it easy to live with

Fine grained white for a bright, contemporary look

Big gravel look, with greige and white tones predominating, Alpina White is beautiful, and incredibly forgiving in a busy kitchen

Fine grained, metal-coloured grey with a fine sparkle, Aluminio Nube is a great example of a product where Silestone lead the way and many others followed

Blanco Stellar is THE classic white mirror quartz. In the last 8 years we have probably fitted more quartz worktops in this Silestone than any other

Grey mirror quartz

Black mirror sparkle quartz – was a hugely popular alternative to Black Galaxy Granite

Beautiful soft sandy-coloured quartz with subtle marbling

Warm, beach-like shingle. Very practical

Extreme white quartz; benchmark product for the best white quartz materials

Delicate white veins on a light grey ground, Serena is one of the more economical stones in the Eternal range

Very smooth, very smart: Kensho is a stunning even grey

An early marbled design, but still has its place

Like Lagoon, one of the earliest marble-white products. Looks a little unrealistic now, but still has its fans for surface finish and practicality.

What Kensho is to grey, Unsui is to brown. Smooth and beautiful

Delicately veined white marble quartz

Beautiful veining on a dark grey ground

With a nod in the direction of Emperador marble, deep chocolate tones, long veins and occasionally sparkly detail

Prominent white veins on a black ground

Bright white with very subtle marbling

Brilliant white, which lends itself to the contemporary kitchen style

Delicate and beautiful, one of the loveliest and gentlest of the long-vein marble-look quartz materials available

Bold and not over-fussy veining in this high-end variant on the Calacatta marble look

Eternal Calacatta Gold is established as a very fine Calacatta marble copy. The veining is pale in comparison with the version from Classic Quartz. See our case study of the Silestone product.
