SANGEMARMAR MAKRANA MARBLE

By Manish Jain luhadia | Architect & Urban Planner

When we think of the world’s most iconic architectural wonders—such as the Taj Mahal in Agra or the Victoria Memorial in Kolkata—we are looking at the enduring legacy of Sangemarmar Makrana Marble. For centuries, Sangemarmar Makrana Marble, popularly known as Sagemarmar marble or Makrana Marble, has been regarded as one of the finest natural building stones in the world. Quarried from the historic Makrana region of Rajasthan, this marble has adorned iconic monuments numerous Jain temples, royal palaces, and heritage buildings across India.

Unlike many imported marbles, Makrana Marble is not merely appreciated for its aesthetic appeal but is also recognized for its exceptional geological properties, structural strength, longevity, and weather resistance. Its outstanding performance has earned it the distinction of a Geographical Indication (GI) registered product, protecting its unique origin and identity.

Often compared to its premium European counterparts from Italy and Greece, Makrana marble possesses a distinct geochemical and structural blueprint that makes it uniquely resilient, exceptionally radiant, and geologically superior for long-term exterior and interior applications. Below, we break down the exact physical, chemical, and mechanical properties that define this legendary natural stone, alongside its traditional extraction and processing workflows.

Geological Origin

Makrana Marble is extracted from the Aravalli geological formations, among the oldest mountain systems in the world. The marble deposits are believed to have undergone metamorphism over billions of years, resulting in exceptionally dense crystalline structures.

The production zone extends approximately 20 km across:

• Makrana Tehsil
• Parbatsar Tehsil

in Nagaur District, Rajasthan, between:

• Latitude: 26.95° N – 27.07° N
• Longitude: 74.6665° E – 74.7270° E

The Makrana marble belt consists of 15 geological blocks divided into six major marble bands, each producing distinctive grades of marble.

Chemical Composition

One of the defining characteristics of Makrana Marble is its remarkably pure mineral composition. Typical composition includes:

Component	Approximate Percentage
Calcium Carbonate (CaCO₃)	≈98%
Magnesium	Negligible
Iron Oxides	Negligible
Silica & Alumina	Slightly higher than Italian marble

The exceptionally high calcium carbonate content is responsible for:

• Brilliant natural whiteness
• High polish retention
• Superior translucency
• Excellent weather resistance

Unlike many imported marbles, the negligible iron and magnesium content minimizes oxidation, allowing Makrana Marble to retain its original white appearance for centuries.

Physical Characteristics

Physical Property	Makrana Marble Characteristic	Engineering Advantage
Porosity	Significantly lower than imported European fine-grained marbles.	Prevents the infiltration of water, dust, and soot, allowing the stone to retain its pristine white color for centuries.
Solubility	Low solubility under atmospheric moisture.	Withstands acid rain, humidity, and intense weathering cycles without structural degradation.
Compressive Strength	3 to 4 tons per cubic inch	Capable of bearing immense structural loads (A cubic foot weighs approximately 2 maunds and 7 seers).

“The coarseness of grain in Makrana Marble makes it resistant to weathering. Its purity enables it to maintain its white surface color over many decades. Its translucence gives it delicate softness… These qualities make Makrana Marble unique when compared to any other marble in the world.” — Preliminary Report on Makrana Marble Quarries, Shri. K.H. Bhola (State Government of Rajasthan, 1935)

1. Hardness

Makrana Marble is generally harder than many Italian and Greek marbles. Its greater hardness results in:

• Better abrasion resistance
• Lower surface wear
• Improved flooring performance
• Longer service life

An additional advantage is that it contains no free silica, making cutting and polishing easier while reducing wear on processing tools.

2. Grain Structure

Makrana Marble is classified as a medium to coarse-grained crystalline marble. Unlike imported fine-grained marbles, its crystals are:

• Closely interlocked
• Non-angular
• Uniformly distributed

This crystal structure provides:

• Greater compressive strength
• Better resistance to cracking
• Enhanced translucency
• Superior polishing characteristics

The subtle translucency creates the soft glow that has made Makrana Marble famous in monumental architecture.

3. Low Porosity

Porosity is one of the most critical parameters for exterior stone. Makrana Marble possesses significantly lower porosity than many imported marbles. Benefits include:

• Minimal water absorption
• Reduced dust penetration
• Better stain resistance
• Lower biological growth
• Improved freeze-thaw durability
• Long-term color stability

Because contaminants cannot easily penetrate the stone, Makrana Marble preserves its natural appearance over generations.

4. Low Solubility

Makrana Marble exhibits excellent resistance to atmospheric weathering. Its low solubility enables it to withstand:

• Rainwater
• Humidity
• Atmospheric pollutants
• Environmental aging

The enduring brilliance of the Taj Mahal serves as one of the strongest demonstrations of this characteristic.

5. Strength

The structural strength of Makrana Marble results from:

• Uniform crystal distribution
• Dense interlocking grains
• High mineral purity

Reported compressive strength ranges between 3–4 tons per square inch, making it suitable for:

• Heavy flooring
• Monumental structures
• Staircases
• Structural cladding
• Heritage restoration

Why Does Makrana Marble Last for Centuries?

The exceptional durability of Makrana Marble can be attributed to the combination of:

• High calcium carbonate purity
• Negligible iron and magnesium
• Dense crystalline texture
• Low porosity
• Strong interlocking crystal structure
• High compressive strength
• Excellent polish retention

These properties enable the marble to maintain its beauty even after hundreds of years of exposure.

Mining and Production

Makrana Marble is extracted through carefully controlled mining operations from quarries ranging between 20 and 75 metres in depth.

The production process consists of several stages.

1. Mining and Extraction

Large marble blocks are extracted through controlled excavation and blasting.

Heavy-duty cranes lift the blocks from deep quarries while smaller stone fragments are utilized for lime production.

2. Dressing

Large blocks are squared using dressing machines to remove irregular surfaces before processing.

3. Diamond Gang Saw Cutting

Prepared blocks are sliced into slabs using Diamond Gang Saw Machines, producing slabs of varying thicknesses with high dimensional accuracy.

4. Edge Cutting

Slabs are further cut to required dimensions using precision cutting machines.

5. Installation

Makrana Marble installation requires highly skilled craftsmen due to the precision necessary for achieving seamless joints and surface alignment.

6. Polishing

Mechanical polishing develops the marble’s natural brilliance while preserving its crystalline texture.

Interestingly, continuous use often enhances the polish, making the surface even more lustrous over time.

Human Skill Behind Every Slab

Makrana Marble is not merely an industrial product; it represents generations of craftsmanship.

Human expertise is involved throughout the production cycle:

• Quarry workers
• Crane operators
• Stone dressers
• Saw operators
• Edge cutters
• Marble fitters
• Polishers
• Traders
• Handicraft artisans

The Makrana region supports approximately:

• 900 operating marble mines
• Over one lakh people employed across mining, processing, trading, handicrafts, and installation.

This makes the industry a significant contributor to Rajasthan’s economy.

Geological Resources

The Makrana marble belt contains an estimated 55 million tonnes of marble reserves.

Among its various marble bands, the Chausera Range is regarded as one of the most prized due to its exceptional whiteness and quality.

Current production is approximately 6.5 million tonnes annually, ensuring sustained availability for decades while supporting large-scale construction and restoration projects.
