Repairing commercial gemstone surfaces, such as those made from materials like onyx or agate, is possible if damaged. The extent of the damage will determine the repair process and whether it can be fully restored. Minor chips or scratches can sometimes be polished or filled to restore the surface’s integrity. Professional repair services may be required for more significant damage, such as large cracks or breaks. These specialized services can assess the damage and employ techniques like epoxy resin or color-matching repairs to restore the gemstone surface as closely as possible to its original condition.
