Two readings of the same material
Vein-cut travertine generally presents a linear, banded appearance. Cross-cut typically reveals a more cloud-like pattern. The exact result depends on the block, so review photographs of the material being proposed rather than a generic category image.
Think across the whole elevation
Linear veining can establish a strong direction on a wall. Mark that direction in the drawings and review panel joints together with the stone layout. A single appealing sample does not show how a room-sized installation will read.
Choose the fill and finish together
Filled and unfilled surfaces have different appearances and care implications. Ask to see the proposed fill colour and finish in a physical sample. Check suitability for the location with the designer and installer, especially where cleaning and moisture are concerns.
Ask for a representative range
Natural variation is part of the selection. Request enough reference images to understand the expected range and agree the limits before fabrication. Keep approved samples available during inspection.
Put the decision in the RFQ
Include cut direction, fill requirement, finish, thickness, quantity and intended use. For coordinated wall panels, add the elevation drawings and preferred vein direction.
