| Chiselled finishes are a pale blue-grey colour with thin sharply contrasting dark grey to black parallel lines. Crinoids will form a randomly distributed pattern of paler grey flecks.The surface has a series of smooth parallel incised curved surfaces separated by thin lines of darker limestone. These will have minor imperfections where the calcite crystals or crinoid traces have fractured during the machining. The appearance will vary depending on the orientation of the grooves and the interplay of light and shadow on the surface. |
