G664
Origin: China (Fujian Province, Luoyuan County)
Material: Natural stone (granite; commercially known as G664 / Bainbrook Brown / Luoyuan Red)
G664 is a warm grey-to-brown granite with fine, even grain and soft natural speckling. In memorial production it’s used when partners need a balanced “warm neutral” that reads professional, stable, and easy to match across standard programs—especially for upright sets, bases, and multi-piece production runs.
Visual Character (Color & Pattern)
Tone: Warm grey / cocoa-brown with subtle red-brown notes (lot-dependent)
Pattern activity: Low to medium; fine “salt-and-pepper” grain
Texture: Even, consistent; reads clean on large faces
Finishing Behavior
Polished / Gloss: Best color depth and contrast; recommended for primary faces
Honed / Matte (if specified): Softer, more muted appearance (confirm per order spec)
Engraving & Readability
Recommended: Polished inscription fields for crisp lettering and portraits
Medium-light base tone works well for dark inscriptions; choose more uniform areas for portraits / large text
Recommended Applications (Memorial / B2B)
Uprights, slants, ledgers, bases, multi-piece sets
Strong for warm-neutral programs where black/grey feels too cold
Why It Works for Partners (B2B)
Stable program color: warm neutral that’s easy to place in mixed collections
Production friendly: typically fine/even grain supports repeatability
Photography & display: polished finish presents clean and “premium-practical”

Quality & Matching Notes
Tone control: keep the lot consistent (red-brown can shift slightly warmer/cooler between blocks).
Grain uniformity: typically fine and even—approve against a control sample for large sets.
Finishing: polished finish shows color depth best; other finishes may read more muted (confirm per order spec).
The highest quality black granite with exceptional polish retention and minimal porosity. Ideal for premium memorials requiring deep, consistent black color.
