No, as some materials are very consistent. However, other colors may change in color, shading or veining throughout the entire slab. Since engineered quartz, solid surface and plastic laminate are man-made, the pattern is consistent with the sample that you viewed. Please note that the choice to view your material is up to you, however if you choose not to view your material (natural material) prior to fabrication, you will be required to sign a waiver. All natural material (granite, marble, onyx, soapstone, limestone, etc.) are products of nature and NO two pieces are exactly alike. Color Veining and texture may differ with each piece. ABSOLUTELY NO CLAIMS WILL BE ACCEPTED AFTER FABRICATION FOR REASONS OF COLOR, TEXTURE, CONSISTENCY OR VEINING.
