Types of stone
Following you will find a detailed description of the stone offered by our Company: granite, marble, quartz conglomerate, natural quartzite, lapitec, onyx, travertine and sintered quartz.
It is comparatively frequently found plutonic ingenious rock. It is usually found in the form of a medium or coarse-grained stone and it can boast of a wide variety of colours from black, red and green colours to grey, pale pink or golden ones. It is relatively easy to extract blocks of this stone. Moreover, its wealth of colours and the possibility of cutting it in any possible way as well as of polishing it, has made it widespread material both in the construction and in the memorial industries. Properly polished and impregnated, products made of stone will maintain their timeless beauty for many years to come.
Application and uses: it is versatile material and it stands up well indoors and outdoors. It is suitable for almost everything ranging from building elevation, kitchen countertops, stairs, window sills, fireplace surrounds, headstones, tombs and much, much more.
Unlike granite, marble is a metamorphic rock (i.e. metamorphosed from limestone or from dolomite. It is composed mainly of calcite and dolomite. Already in the Ancient Times, marble was used as building and as ornamental material (also to carve sculptures). Marble occurs in a variety of colours, ranging from whites, through browns, greens, greys to very dark ones (almost the black ones). However, marble is characterised by a low resistance to abrasion and to acids, hence it is not used for the exteriors in our climate conditions.
Application and uses: construction material for indoors ( except for kitchen worktops - it is too soft.
Quartzite conglomerate offers an interesting alternative to natural stone. It combines modern technologies with the creation of nature. It combines 93% of high quality and hard quartz with 7% of natural resin with added pigments, owing to which a rich palette of colours can be gained.
Quartzite conglomerates are characterised by a high hardness ratio, resistance to scratching and to acids. Moreover, quartzite conglomerates are water and liquids impermeable, by dint of added resin, which makes them stain-proof and free of bacterias. Even the most demanding Customer will be able to find the shade of colour, which suits them most. However, quartzite conglomerates are definitely more expensive than natural rocks and they do not tolerate high temperatures. For that reason, they are not suited for fireplace surrounds and they are not recommended for kitchen worktops, otherwise you will have to avoid placing hot dishes and pots on kitchen worktops.
Application and uses: in the interiors (window sills, countertops, stairs and all other elements.) apart from fireplaces.You can install kitchen worktops made of quartzite conglomerates at your own risk - there is no warranty for high temperatures.
Like gneiss, natural quartzite is metamorphic rock transformed of existing rocks in a process called metamorphism. In this case, it is the metamorphism from either silts or sandstone.
In most cases, its structure consists of fine-grained quartz crystals, metamorphosed as a result of high pressure and temperatures. Unlike sandstone, from which it originates, natural quartzite does not have such tangible grain size distribution and roughness. It is hard and much more compact. Its basic properties are: relative durability and toughness, stain-resistance and comparatively low water absorption (being higher than of granite, it will retain water much longer).
Application and use : natural quartzite is versatile material, suitable for both indoors and outdoors.
Lapitec is a material created by man, sintered into big slabs by means of an innovative method. Lapitec combines a diversity of aesthetic values, big sizes and durability with the properties of technical porcelain with the texture and the ease of being treated, retaining its elegant form and colouring. Lapitec is not porous stone and it does not absorb any liquids, which translates into its resistance to stains. Owing to its consistent structure, Lapitec is free of mould and bacterias. Its unquestionable advantage is an easy care and maintenance (with a little bit of warm water and a soft cloth). This material will sturdily defy the tooth of time due to its durability, resistance to atmospheric influences, basis, acids and various solvents. Moreover, it is very hard material, resistant to any kind of mechanical activity and abrasion, being frost proof and insensitive to UV radiation. Incidentally, its resistance to graffiti is invaluable.
Application and uses: Lapitec is versatile material and as such can be used both indoors and outdoors. It is suitable for any kind of products: building elevations, sculptures, kitchen worktops, stairs, window sills, fireplace surrounds etc.
Onyx is another alternative for creating decorative elements. It is natural stone, which is becoming more and more popular. Although it is very expensive, onyx produces incredible effects when mounted.
Onyx has got unprecedented structure, which transmits light rays producing a naturally coloured mosaic light. Backlighted by Led light, onyx emits a distinctive glow, which adds colour and uniqueness to every interior. Every slab is characterised by an individual and unequalled arrangement of veins. Onyx ideally complements all the sumptuous interiors in the glamour style, satisfying even the most sophisticated tastes.
Application and uses: decorative walls, ceilings, floor or fireplace cladding.
This popular stone has a broad spectrum of excellent uses. It is unique as a decorative element. Owing to its variety of colours, travertine can be used to create charming and harmonious compositions. Travertine is relatively durable and it will serve you for many years to come. Its only drawback is its porosity.
Application and uses: in the interiors (floor and wall cladding, fireplace surrounds, countertops, stone stairs)
It is a novelty on the Polish market. It is worth remembering sintered materials are composed from natural minerals only (for example: granite rocks, ceramic pigments, quartz sand). All these materials are ground first, then pressed and finally sintered in specially designed hybrid ovens. The methods of grinding and pressing of these materials, based on a strict formula, have an effect on their colour and their colour tone. Sintered materials are extremely resistant to high temperatures, scratches, acids, changeable weather conditions. Undoubtedly, even the most demanding clients will be able to find the most desired shade of colour. Nevertheless, sintered materials are definitely more expensive than natural rocks. The thinnest slabs are 1,2 cm thick. The problem with sintered material is that they make a „ringing” sound when you place there any object.
Application and uses: both the exteriors and the interiors. It is suitable for any kind of products: building elevations, sculptures, kitchen worktops, stairs, window sills, fireplace surrounds etc.

Kwarcyt to naturalny kamień, który dzięki swoim właściwościom znajduje szerokie zastosowanie w wykańczaniu i aranżacji wnętrz. Ma bardzo mocno zbitą strukturę, jest twardy, wytrzymały, odporny na zniszczenia i plamy. Te cechy sprawiają, że idealnie sprawdza się, jako materiał do wykonywania parapetów, blatów kuchennych, podłóg, a nawet obudowy kominków. Dodatkowo wizualnie przypomina marmur, więc każdemu wnętrzu doda elegancji i niepowtarzalnego stylu. Co jeszcze kryje się za popularnością kwarcytu?
Największą ozdobą onyksu jest jego barwa. Najpopularniejszy jest kolor czarny, złożony z występujących kolejnych warstw białej i czarnej, ale równie pięknie prezentuje się w kolorze zielonym. Nic dziwnego, że cieszy się on popularnością w branży jubilerskiej. Dzisiaj jest on wykorzystywany przez architektów i projektantów wnętrz. Ze względu na jego nieprzystosowanie do niekorzystnych warunków atmosferycznych, wykorzystuje się go do elementów dekoracyjnych wewnątrz budynku. Jego największą ozdobą jest to, że jego struktura pozwala na przepuszczanie i rozczepianie promieni światła, dlatego bardzo dobrze prezentuje się podświetlony. Dlatego często przed jego montażem pod spód kamienia, zakłada się stelaż ze źródłem światła. Pozwala to uzyskać niepowtarzalny efekt. Każda jego płyta ma unikalne ułożenie słojów.
