Nero Black Portora Oval Knoll Table – Chip on Edge Before Repair
The edge of this Nero Portora oval Knoll table shows a chip break photographed during repair. The table top is resting on a work surface protected by film. The black stone with its dramatic bold white veining is visible, and the damage appears at the curved rim where the thickness of the slab was compromised.
Chip repair on a table like this requires saving any broken fragments if possible. The fragment can be bonded back with stone adhesive, then the joint is ground and polished to blend with the surrounding surface.

When the original fragment is missing or too small to bond, a matching polymer resin tinted to the stone color is used as fill. On black marble with white veining, matching the color is straightforward but matching the vein pattern requires skill. The result, if well done, is a chips repair that reads as solid stone from normal viewing distance.
