Natural Stone: Quality Certified

quality-certificatedQuality is: natural product, sustainibility, environmental responsibility

To demonstrate the high quality of our product – we supply first choice blocks, slabs and semi-finished products, selected from the best lava stone quarries – Ranieri Pietra Lavica certificate its product with the trademark “Natural Stone”.


“Natural Stone”


In the ambit of promoting and safeguarding natural stone products from attacks by poor ceramic or agglomerate imitations, Euroroc (the Federation of European stone industries) has created a trademark for products born in the heart of quarries. “Natural Stone” means “genuine stone”: Natural Stone loudly and clearly states the authenticity of the natural product as opposed to the falsity and artifice of manmade marbles and granites. Natural Stone is a collective trademark now shared by stone industries in all 25 European Union countries – it should be borne in mind that the idea stems from two basic aims:

TEAMING UP the whole European stone industry under a shared and clearly recognizable emblem, a single logo valid for stone producers in Italy, Spain, Germany and all the rest of the 25 states in the Union;

DISTINGUISHING products in genuine stone from those in ceramic and agglomerate. The “genuine stone” communication campaign is a decisive one for the Italian and European stone industries, a campaign that in coming months will involve not only sector operators but also designers, architects and final consumers.

Lava Stone characteristic & Peculiarities

What is faulty product when we go for natural organic stones and handcrafted finishing?

The Lava stone may be subject to variations in shade and occasional “aesthetic imperfections” that are just peculiar characteristic of both natural stone and handcrafted finishing.
The understanding of the gray and enameled lava stone features is a crucial step, through which our partners and our customers will fulfill their expectations as regards quality and beauty.
Buying a lava stone product, you should be aware that the product may, on occasions, include: pinhole cavities, darker spots, green spots, mineral spots, for which there is a tolerance parameter as shown in the photos.
Another peculiarity of the lava product is the possible slight variation in the size, in the range of +/- 1.5 mm, due to the dilatation during the firing.
The enameling process itself may cause a variation in the thickness of the piece, in the range of +/- 0.5 mm.

variations in shade

Another feature which may occur on lava stone surfaces is the variations in shade. All the natural products vary in shade and in the structure of the piece.
The pieces undergo an exhaustive sorting process at Ranieri Lava Stone and any that do not meet our quality standards are rejected, nevertheless, variation in shade may affect both the gray lava surface, as part of the natural stone, and the glazed lava surface, as part of the glazing process.
As a matter of fact, the variation in shade is an inherent part of the glazing process, where it may occur due to the accumulation of enamel along the piece end edges, and more generally as a result of the craft enameling.
The shade variation can be an added value of crystalline colors, while matte enamels are not affected by this feature.
Shade variation is unpredictable; its occurrence makes each piece unique and unrepeatable.
The feature is part of the beauty of the lava product.

The shade variation is part of the beauty of the lava product. Anyway, if you have chosen one of our products for your project, we suggest you request a few samples before making your purchase.
