I do not have access to the latest information about the thickness of Brazils Jade Quartzite slabs. However, based on my limited knowledge, the thickness of slabs can vary depending on the manufacturer and the intended use. Some standard thicknesses for slabs are 2 cm and 3 cm, while thicker slabs can range up to 10 cm or more. It is always recommended to check with the supplier for the specific thickness of the Jade Quartzite slabs.
