The grain shape of marble is typically interlocking. This means that the individual mineral grains in the marble are tightly interwoven or interlocked with each other, forming a solid and dense structure.
Nonfoliated
Limestone grains are interlocking. The simple test to see if a rock's grains are interlocking is to put a drop of water on the surface. If the rock is interlocking, the water will remain on the surface. If it is not interlocking, the water will start to percolate through the rock. :).
The metamorphic rock that lacks mineral grains with long axes in one direction is called marble. Marble is formed from the metamorphism of limestone or dolomite, and its grains do not exhibit a preferred orientation or alignment. It often has a smooth and uniform appearance, making it a popular material for sculptures and architectural purposes.
Marble is a sedimentary rock, which consist of limestone that has undergone heat and pressure metamorphosis under temperatures in excess of 1800ºF. The texture of marble depends on the form, size and uniformity of grains. The element components of marble determine the color of the stone.
It is made from calcium carbonate.
Marble is a rock and rocks don't have crystal structures. However, marble does have a crystalline texture of visible interlocked calcite or dolomite mineral grains.

Igneous rock has interlocking grains with no specific pattern.
Chemically, a quartz sandstone is different than a calcitic marble. Additionally, they are classified differently by their method of formation. Sandstone is a sedimentary rock, and marble is a metamorphic rock. Sandstone has cemented grains, and marble has interconnected crystals.

Pure marble is the result of metamorphism of a very pure limestone or dolomite. Colored marble varieties are usually due to various mineral impurities such as clay, silt, sand, iron oxides, or chert which were originally grains or layers in the limestone.
Those would be non-foliated metamorphic rocks, like quartzite and marble.

Marble is hard and durable, which makes it appeal to everyone. Marble and granite are both expensive, but complement homes in a great way.
