Know the stone before it’s set.

Blue Select or full-range? Thermal or natural cleft? A short guide to the stones we set — what they are, where they shine, and how they age.

The Stone Library

Six stones. One standard.

Every project starts with premium natural stone — selected for strength, color, and the way it ages. Edgar brings samples to the site visit.

Bluestone

Blue Select Bluestone

The most uniform grade of Pennsylvania bluestone — dense, cool, blue-gray and refined. The formal choice for terraces, steps and caps.

Character
Uniform blue-gray
Best for
Formal patios, treads, caps, counters
Finish
Natural cleft or thermal
Flagstone

Pennsylvania Flagstone

Irregular, natural-cleft bluestone flagstone — in Blue Select, or in the full natural range of blues, lilacs, rusts and browns for a warmer, older-looking terrace.

Character
Mixed earth tones
Best for
Terraces, walkways, informal patios
Finish
Natural cleft
Bluestone finish

Thermal Bluestone

Bluestone whose surface has been flamed with intense heat, leaving an even, finely textured face that grips underfoot.

Character
Even, textured surface
Best for
Pool decks, steps, entries
Why
Slip-resistant, consistent
Granite cobble

Belgian Block

Rectangular granite cobble — nearly indestructible. The border that holds a driveway’s line for generations.

Character
Gray granite, squared
Best for
Driveway borders, aprons, edging
Why
Strength under vehicle loads
Wall stone

Natural Fieldstone

Weathered, hand-split stone with depth and shadow — walls and chimneys that look like they grew where they stand.

Character
Weathered, irregular
Best for
Walls, chimneys, fireplaces, veneer
Why
Texture and age from day one
Landscape stone

Boulders

Whole natural stones, placed by eye and by hand — for stream beds, water features, steps and naturalistic walls.

Character
Natural, sculptural
Best for
Water features, koi ponds, terraced walls
Why
Permanence and calm
How to choose

Three questions Edgar will ask.

  • Formal or natural? Blue Select reads tailored; full-range and fieldstone read relaxed and old.
  • Bare feet or boots? Around pools and on steps, a thermal finish gives grip and an even surface.
  • What does the house say? The stone should belong to the architecture — brick, siding, or stone already on site.
Caring for it

Stone grows more beautiful with age.

  • A white haze in the first months is efflorescence — natural salts. Brush it dry; never acid-wash.
  • In winter, use sand or calcium magnesium acetate — never rock salt.
  • Sealing is optional, never required. If you seal, use only a breathable, penetrating sealer — and call us first.
Final Folio — The Commission

Commission the stone that outlives you.

Edgar personally walks every site before a single figure is written. Estates are accepted by private consultation — a limited number each season.
