The mystery of color difference of stone: is it a flaw or a natural beauty?

In the past few decades, people with obsessive-compulsive disorder have had little fondness for color differences. Many people prefer a neat, single, and simple design style. When encountering color differences in stone, people are always eager to eliminate color differences or hope to choose stones with smaller color differences. But in the eyes of designers, stones with color differences are actually treasures. Color difference engineering is the highest art in nature, and the greater the color difference, the more precious it is. Natural is the best. Why is that?

 

No two leaves are identical in the world.” -- Gottfried Wilhelm Leibniz (German philosopher)

No two stones are identical in the world.” -- Men in stone business

 

The natural color difference is precisely the charm of stone. By taking advantage of the color difference, the entire space will bloom with a unique charm. Many clients believe that the quality of the materials used is poor, but in fact, this is a misunderstanding of the stone materials.

 

Reasons for color difference in stone

 

Stone mine and quarry

 

Reason 1: Surface and deep mineral deposits

 

Stone is extracted in batches from mines to quarries, from top to bottom, from outside to inside. In the natural environment, the outer layer of stone is more exposed to water, air, and sunlight. However, the stone hidden deep inside does not have such an environment. Therefore, there is a general difference in color between surface and deep minerals. After deep mining, the stone will also undergo changes in color under new environments such as sunlight, air, and water.

 

Reason 2: Uneven mineral content

 

The basic material of marble is calcium carbonate (limestone). In addition to basic minerals, various elements and minerals are mixed together to form the ever-changing colors and textures of stone. Taking stone from South America as an example, the geological movement in South America is strong, and the underground is rich in copper, iron, and various metallic minerals. Therefore, stones produced in South America usually have large variations in texture and rich colors. The distribution of various minerals in nature is uneven, otherwise humans would not need to explore mineral deposits. This unevenness causes differences in the color of the stone.

Reason 3: Different methods of mining and processing

 

The stone extracted from the mine is usually a whole block of raw material, which needs to be cut into pieces, which we call large slabs. In the processing of raw materials, there are different cutting directions. This kind of processing difference cannot be completely avoided even with great attention during stone processing, and the cut slabs will have more or less differences.

 

Reason 4: Different degrees of surface processing

 

The color of the rough and smooth surfaces of the same stone variety is different. In smooth surfaces, the difference between polishing to 10 degrees and polishing to 50 degrees, 70 degrees, and 90 degrees is also very obvious. The brighter the grinding, the more obvious and vivid the stone patterns and colors will be, and the rough surface has a hazy beauty.

Color difference in stone is a natural beauty

 

The natural marble is not an industrial product. Its texture and color need to go through millions of years of geological movement and absorb the essence of nature. It can be said that it is truly "natural beauty". However, stones from different terrains, environments, and levels may have subtle changes in color and texture, resulting in color differences. For example, in China, people from different places such as Shanghai, Heilongjiang, and Ningxia may still have differences, but each has its own beauty.

 

Viewing Color Differences with an Artistic Perspective

 

Firstly, based on the understanding and comprehension of stone, the use of natural stone requires more respect and tolerance towards nature. Stone is formed through complex physical and chemical changes over billions of years, as well as geological movements and evolution, in the natural environment. Many internal and external factors can affect the ever-changing nature of stone. This kind of change objectively exists. The color of stone is naturally formed, and the quality of color is determined by the pigment ions contained in the stone and its internal structure. At the same time, the different minerals that make up the stone form in different sequences, which can also affect the color change. The pure natural texture and luxurious texture are the greatest value of marble. For marble with color differences, we cannot view it as a "defective" product. Marble collected from nature is unique in every piece, with only similar colors and textures, not completely identical. Color difference can form colorful combinations and produce unique effects.

Mastering the art of color difference to make beauty appear effortlessly natural

 

When you appreciate from an artistic perspective and create from a design perspective, you will suddenly realize that color difference has more possibilities. Just like adding similar colors to a painting, changing from 12 colors to 18, 24, or even 64 colors, using good color differences can achieve more layers, spatial sense, and rich beauty, perfectly reflecting the designer's personal customization plan. Resplicing and combining stones with color differences can create unique and unparalleled patterns, even preserving the beauty of defects in specially designed stones with broken lines and holes. In fact, even after post-processing, any dyeing, polishing, or color adjusting materials cannot bring natural beauty and long-lasting effects. Natural creations are not limited by conventions, and nature does not create natural stone according to people's requirements. The perfect stone projects we see are all paved with selected stones from a large amount of stones after screening and selection. The pure natural texture and luxurious texture are the greatest value of marble. For marble stones with color differences, they cannot be viewed as "defective". Marble collected from nature is unique in every piece, with only similar colors and textures, not completely identical. And now this kind of "color difference" that showcases style, taste, and personality is gradually forming a new trend of indoor material popularity. The color difference of stone maximizes its charm, and the natural "color difference" is the most natural and pure beauty that nature gives us.

This kind of "color difference" that showcases style, taste, and personality is gradually forming a new trend. Compared to the monotony and dullness of a single color, this decoration style that is not prone to rigidity and similarity, and is full of personality, is destined to be accepted by people who pursue a higher quality of life.
