Specifications:

  • Material Type: Natural shell limestone (sedimentary stone)
  • Color Range: Light cream to sandy beige with visible fossil/shell fragments
  • Available Formats: Pavers, coping, tiles, slabs (varies by supplier)
  • Standard Thickness (Pavers): 1¼” – 2”
  • Finish Options: Honed, tumbled, brushed, sandblasted
  • Water Absorption: Moderate (typically 3–7%, varies by density)
  • Slip Resistance (Textured Finish): Suitable for pool decks & exterior use
  • Compressive Strength: Medium to high (varies by quarry source)

Note: Exact specifications may vary by manufacturer and quarry origin.


Chemical & Physical Characteristics:

Shellstone Myra is primarily composed of calcium carbonate (CaCO₃) formed from compressed marine shells and fossilized materials. Its structure gives it a naturally porous texture and distinctive organic appearance.

Key characteristics:

  • Naturally cool underfoot (ideal for hot climates)
  • Moderate porosity (requires sealing for stain resistance)
  • Good workability for cutting and shaping
  • Sensitive to acidic cleaners (acid-reactive stone)
  • Breathable material suitable for exterior installations

Because of its fossil content, each piece has unique patterning — no two pavers are identical.


Advantages (Pros):

  •  Natural coastal aesthetic with fossil texture
  • Stays cooler than many dense stones in direct sun
  •  Excellent for pool decks & patios
  • Slip-resistant when properly finished
  • Adds premium, organic look to landscaping
  • Blends well with tropical & Mediterranean designs

Disadvantages (Cons):

  •  Requires sealing to reduce staining
  • Can etch if exposed to acidic substances
  •  Softer than granite or porcelain alternatives
  • Color variation between batches
  • May darken slightly when wet
