Technical Considerations

Geological Formation

Composition & Durability

• Calcite Content:Higher calcite content (90%+) produces whiter marbles but reduces acid resistance
• Dolomite Content:Increases durability but often creates grayer coloration
• Impurities:Iron oxide creates reds and yellows; chlorite creates greens; graphite creates blacks
• Mohs Hardness:Most marbles range from 3-7, significantly softer than granite (6-8)
• Acid Sensitivity:All marbles are vulnerable to etching from acidic substances

Selection Considerations

• Thickness:2cm standard for vertical applications; 3cm recommended for countertops
• Finish Options:Polished (reflective), honed (matte), leathered (textured), brushed (soft texture)
• Seam Visibility:Light-colored marbles generally show seams less than darker varieties
• Maintenance:All marble requires sealing; darker marbles show etching more prominently
• Book-Matching:Sequential slabs can be matched to create mirror-image patterns

Buying Considerations

Slab Selection

Grading Standards

• A Grade:Minimal veining, consistent background, few to no fissures
• B Grade:Moderate veining, generally consistent background, limited fissures
• C Grade:Heavy veining, some color variations, may have visible fissures
• D Grade:Dramatic veining, significant color variations, potential structural concerns

Market Trends

• Extraction difficulty
• Quarry accessibility
• Block size availability
• Current design trends
• Transportation costs
