Thassos marble is an elite, pure white natural stone quarried from the Greek island of Thassos in the northern Aegean Sea. Widely considered the whitest marble in the world, it is renowned for its crystalline structure that gives it a luminous, sugar-like sparkle and exceptional light-reflecting properties.
Physical Characteristics
Colour & Clarity: Famous for its uniform, brilliant white appearance with virtually no veining, distinguishing it from Carrara marble, which typically features grey veins.
Composition: Primarily a dolomitic marble (calcium and magnesium carbonate), which contributes to its superior hardness and durability compared to many other white marbles.
Light Reflectivity: Its high crystalline content allows it to reflect up to 98% of light, making it ideal for brightening dark spaces and creating an airy, expansive feel.
Thermal Properties: It has a low heat absorbance rate, ensuring the surface remains cool even in warm climates.
Common Varieties
While valued for its “total white” look, it is often graded based on purity:
A1 (Select/Extra): The highest grade, featuring a nearly flawless, pure white background with no visible inclusions.
A2/A3: May include subtle pale grey “webbing” or very minor spots, often used to add natural character.
