Honed Marble VS Polished Marble Continued…

Pietra Gray

Sealing is important for both honed and polished marble. Unlike polished marble, honed marble needs more sealing due to having more porosity on its surface. Polished marble is slightly more resistant to staining as its porosity has been reduced by many additional rounds of polishing.

Polished or Honed for Decors?

Unlike polished marble, honed marble is ideal for a certain kind of design aesthetics. It is not as showy as the polished ones but can. It, unlike polished marble, it doesn’t draw the attention much.  However. It can be a perfect choice for organic, natural looks and spice up the war neutral background of the building. It is mostly used for and looks better at Western and beachy styles.

Polished marble, unlike honed marble, polished marble is more an ideal option for the slavish and showy look. Due to its shininess, it can be used for luxe fixtures and ornate lighting. Its appearance makes it perfect for standing alone as a decorative element.  Many halls and grand homes used polished marble to cover the surface. Polished marble can be seen also as an ideal option for modern design.

A Combination of Honed and Polished Marble

The combination works well per se. the polished shiny part draws the attention while the same honed part makes that shiny boldness deeper in front of the eyes.

Caring Polished and Honed Marble

There are some basics that work well for all marbles

  • Always use cutting boards to protect surfaces from staining, and also knives from damage
  • Try to clean the surface of the stone as soon as possible and no spills and food debris remain on the surface
  • Try to use a gentle cleanser to lean the surface with warm water
  • Avoid using some natural cleaners containing lemon juice or vinegar. Because these are both too acidic to be used on natural stone surfaces and can destroy the surface over the years
  • Consider the suggestion of the installer for sealing the surface over a certain period of time.

The difference Between Honed and Polished Finishing Process

Pietra Gray Marble

There are many different kinds of finishing for natural stones. Among all, there is always a similarity between honed and polished ones. In both kinds of finishing, the beauty and true nature of the stone slab doesn’t change at all. But the finishing process may add an extra layer on the stone which adds to secure the surface of slabs against stains or camouflage.

The similarity between the honed and polished finishing

A polished finish slab has a very glossy surface and can reflect light and display the color and veins of the stone better.in fact, the polish finish adds up the beauty of the slab and put more emphasis on the natural characteristics of the stone. While in a honed finish slab, a relatively little reflection of light can be seen. To the eyes, a honed finish seems flatter. Additionally, the degree of honing highly depends on the stone, but it may depend on the kind of stone.

The process to create both honed and polished marble is similar. The honed marble is achieved by polishing with gritty abrasives until the surface is smooth to the eye, but still has many small flaws that prevent a shiny appearance. All polished marbles are honed first. After being honed, polished marble is sanded with smaller and smaller abrasives until surface flaws are removed and the marble is a smooth as possible.

Polished Finish

Consider your marketplace:

Depending on the market you have, both honed and finish markets can work for you. In the market with an emphasis on durability, lack of scratches and etches, the honed finish can work well.  Besides, in honed finish slabs, the surface is less slippery when they are wet. Therefore, they are a better choice for bathroom flooring and staircases.

Honed Characteristics:

Comparing to a polished finish, honed one has already matte and scratches are usually camouflaged or go unnoticed.

Polished Characteristics:

In the polished finish, due to the kind of finishing process and protective layers on the stone, they are less susceptible to stains. However, it doesn’t mean that you can let the stains stay on the countertop overnight.

Honed and Polished Finishes: Stain Resistance

When properly sealed, both honed and polished finishes are stain-resistant. There is no such thing as a stain-proof sealer. If stains are high on your list of concerns, there are a few things to be considered.

A polished finish on a stone is essentially an added layer of security to protect from stains. The process in which a stone is polished helps to close natural pores and create a protective barrier. On the other hand, the pores in a smoothed, honed stone are more receptive to liquid. Side by side, a polished stone surface will have more protection from stains than a honed surface; however, a proper sealer will help to close in open pores and provide stain resistance against most household items.

In brief, the features of honed and polished finishing can be summarized as follow:

Honed stones:

Looks: Matte

Feel: Velvet/Satin

Durability: Scratch resistant, but easily stained.

Maintenance: Regular wipe down with water and mild detergent, clean up spills immediately, re-sealing suggested over time.

Suggested Application: Countertops and high traffic areas, such as floors for the bathroom, foyer, or living room.

 Polished stones:

Look: Glossy & Shiny

Feel: Smooth

Durability: Scratch and etch easily, but more stain-resistant.

Maintenance: Regular wipe down with water and mild detergent, clean spills immediately.

Suggested Application: Kitchen and bathroom countertops, fireplace surrounds, and walls.

What is Sandstone?!!


Sandstone can be described as a kind of sedimentary rock that is formed under the river, lakes, and oceans. In other words, sandstone is formed usually forms on buried or laid down sands. this usually happens offshore from river deltas, desert dunes, and beaches. can be found in sandstone, although the energetic environments where sand beds form doesn’t always favor preservation.

Due to a deeply buried process, the pressure from high temperature causes the materials dissolved and become mobile. These grains will finally bound together and sediment become smaller. when material moves into the sediment, as the result of dissolved materials some fluid is made. That fluid moves the materials forwards. Due to oxidation, the color changes to darker and grey ones. 

In terms of composed mineral particles, Sandstone is very like the quartz. In ancient times, it is usually used for building facing and paving. Sandstone as a perfect material for buildings and exterior. Because of the resistance to Weather, sandstone is a good option to be used for the exteriors like paving, building facing, interior walls, garden benches, patio tables and also swimming pool edges. 

Some Examples of Sandstone Architecture

 Sandstone has good characteristics that make it a perfect choice for the architecture to use in their projects. Among all, natural strength, durability and split resistant properties are some to mention. A very good example of sandstone is The White House of the United States. Two kinds of materials can be seen in sediment particles of sandstone: matrix and cement. Matrix can be defined as the fine-grained stuff in the sediment along with the sand while it is the cement that binds the sediment into rock.

Depending on the percent of sandstone, sandstone can be divided into two groups. Those sandstones with hight percent of rock are called wacke or wacky (dirty). That sandstone with a lot of matrices is called poorly sorted. Those sandstones with a little matrix are called well-sorted.  Also, this well-sorted sandstone with little cement is called arenites (or clean). Moreover, a sandstone with at least 25 percent feldspar is called arkose. Also, a sandstone formed of volcanic particles is called tuff.

It is clear that the particle size in sandstone can define the quality of the stone. On the other hand, minerals play a great role to define the quality of sandstone. The sandstone cam has different colors. The color highly depends on the mix of matrix and cement and its color can range from nearly white to nearly black, with gray, brown, red, pink and buff in between.

Minerals of Sandstone

What can help to distinguish sandstone from limestone is partially related to minerals. Rocks made of carbonate minerals can be defined as limestone and have their own classification.  It can say sandstone is a silicate-rich rock. The difference between limestone and sandstone is that limestone is formed in clean ocean water while sandstone is formed from sediment eroded off the continents.

Granite Countertops: The New Obsession Of The U.S.

Granite is one of the bestselling countertops for the kitchen. Granite can also be used for floors, walls and give the room or area a natural element. It is chosen over other kind of stone due to its beauty, wide variety of color selections, and durability. Granite is formed as the rock is a result of pressure and extreme heat from the slow crystallization of magma beneath the Earth’s surface. Comparing to other kinds of natural stones, granite is quite heat resistant. For example, placing a hot pan on a well-maintained granite slab will not cause it to crack or weaken.

Among other good features of granite, it’s worth mentioning that granite wont scratch, if it sealed, it lasts for many years because the sealing helps protect against stains. If they are treated properly, there is no need for reseal for another decade. Granite countertops give a unique beauty to any kitchen, bathroom or anywhere in a home. It has so many colors and very cost effective. Granite has always been first choice for many designers and architects. Recently, granite has been widely used around the world especially the U.S. some reasons are as follow:

Import is most cost consuming than extraction

Iran is one of the main suppliers of qualified granite in the world. Although, United States has granite, but other countries could provide more at a lower price. That led to more countertops, creating a cycle in which supply and demand surged. For this reason, based on estimates from the US International Trade Commission, total United States imports of processed granite were about 206,000 metric tons in 1996. In 2014, they exceeded 2 million metric tons.

Shipping granite got easier

Comparing to local granite, the global granite became more easily shippable, it became more affordable for builders and consumers. Since granite slabs for countertops could be precut on site and then safely packed and shipped, it is possible to get granite from around the world.

 Granite and new trend of home construction

One of the most important reasons for the U.S. obsession with granite is more likely the trends in home construction during the 2000s. it has made people, designer and architect have a different implication of what a “good” countertop looked like.It’s worth mentioning that using granite in the home construction is very beneficial in terms of    cost, durability, beauty and color. Recently, it is highly demanded by the U.S. for the impression of luxury, beauty and durability.

Natural Stones In Ancient Buildings In Iran

Natural stones in ancient buildings in Iran

Natural Stones & Ancient Buildings

The use of natural stones in Iran has a long history. In the ancient time, natural stones have been used to form civilization in Iran. The remaining buildings and works from that time can speak for itself.  Among all, PersepolisPasargadae and many other Islamic buildings can be named.

There are totally billion tons of natural stone resources in the world including Granite, Marble, Onyx and Travertine.  4.7 Million tons of resources are in Iran. That makes Iran the fourth country in the world for supplying natural stones. However, in terms of color variety and quality, Iran is ranked the first in the world.

Many decorative objects made out of Marble and Onyx used as dishes and jewelry are now exhibited in museums of Iran and other countries. Discoveries also show that, these rocks were used as interior decoration in buildings. Discovery, extraction, transportation, cutting, polishing and using natural stones which were performed in traditional ways, has been transformed profoundly in recent decades. The most important part of this transformation is using modern methods in production and use of these resources. Using Non-explosive extraction methods and deploying hard-cutting machines are the most important changes in Iran’s rock industry, which have taken place in the recent decade and have expanded production and consumption of natural stones.

History of Using Natural Stones

Application of rocks in buildings dates from 12 thousand years ago, and discovering ancient structures like the Egyptian pyramids and structures in Iran and Rome has stunned many people, considering the technology at that time.

Application of stones started with using large blocks, but as the technology went on, weight of stones decreased and they paid more attention to color, polishability, texture and strength of the stones. Nowadays stone plates that are beautiful, colorful, polished and low in thickness are used more frequently.

Pasargadae (Tomb of Cyrus the Great)

The stones that are used in Pasargadae and Persepolis include white limestone (similar to Onyx), grey stonesimilar to Granite in hardness and sometimes black Marble which is very fragile. The black stone used in Pasargadae after 25 centuries has become very fragile and is easily broken into pieces, but the other 2 types are very durable.


Two main kinds of stones are used in the structure, light-colored and grey stones. These stones were carried to desired places in blocks as heavy as 30-40 tones, and the weight of only one of the columns is 17 tones.
