Silestone by Cosentino - Big Brand in Quartz around the World

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 SilestoneÂ

Silestone - Product Range
Cosentino is in the forefront of technological innovation and product design, with many cheaper manufacturers simply trying to copy what the Silestone labs have produced.
Silestone worktops include the stunning Eternal Range, written up on our blog at its launch.
Our listing, below, of Silestone materials isn’t exhaustive – other Silestone quartz worktops are available: for Cosentino’s own page of Silestone worktops, look here. The products are grouped into price bands below – but remember, where we do not stock a stone, the price for buying it specially on a bespoke basis may be far higher than it would be for a more expensive stone that we hold in stock.

Silestone - Group 1
Blanco City
Grainy and sandy coloured – incredibly practical, easy to live with and excellent value for money!
Gris Expo
The grey equivalent to Blanco City – liveable, economical, durable
Marengo
Darker grey than Gris Expo, and not quite as easy to live with, but an economical choice if you need a darker option.
Silestone - Group 2
Arden Blue
Dark grey with a slightly “clumpy” texture in the pattern
Blanco Maple
Beautiful, large-grained, warm white. Bright and practical with no bling element
Cemento Spa
Cemento Spa is THE smooth darker grey from Silestone, just at the sweet spot between reasonable price, smoother granulation and great surface quality.
Coral Clay
Natural textured pattern in a warm greige; good looking and punches above its weight on price
Ironbark
Warm chocolate brown with a good marbling which makes it easy to live with
White Storm
Fine grained white for a bright, contemporary look
Silestone - Group 3
Alpina White
Big gravel look, with greige and white tones predominating, Alpina White is beautiful, and incredibly forgiving in a busy kitchen
Aluminio Nube
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
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
STOCK MATERIAL

Grey mirror quartz
STOCK MATERIAL
Negro Stellar

Kensho
Very smooth, very smart: Kensho is a stunning even grey
Lagoon
An early marbled design, but still has its place
Lyra
Like Lagoon, one of the earliest marble-white products. Looks a little unrealistic now, but still has its fans for surface finish and practicality.
Unsui
What Kensho is to grey, Unsui is to brown. Smooth and beautiful
White Arabesque
Delicately veined white marble quartz
Silestone - Group 5
Charcoal Soapstone

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