Due to the fragile nature of stones, we cannot offer any warranty on them. This is standard industry practice. If a stone was broken or cracked due to delivery negligence, please contact us immediately.
Unfortunately, we cannot replace stones that have small chips in them. Because the manufacturing process quite often results in imperfections and chipping along the edges. These chips do not alter the performance of the stone or oven, therefore are not considered a defect. If a customer finds chips on the stone bothersome, we recommend rotating the stone when possible to achieve the smoothest surface or touching up the edge with sandpaper
