G623

Origin: China.
Stone Description

G623 is a light grey, fine-grain granite with evenly distributed darker mineral speckling. It’s used when you need a clean, neutral grey that engraves well and stays visually consistent across larger programs.

Typical Use (B2B)

Monuments, memorial bases, exterior cladding, paving/steps, kerbs, and general architectural stone where a balanced grey tone is required.

Quality & Matching Notes

Shade/texture: generally uniform, but grey tone and speck density can shift between quarry lots—request a control sample for approvals.

Batch control: for one project, book from the same block/lot and keep reference photos/sample on file.

Finish effect: honed/flamed finishes typically read lighter/more matte than polished—confirm finish before final matching.
