The mineral that can scratch garnet is topaz. On the Mohs scale of mineral hardness, garnet has a hardness of about 6.5 to 7.5, while topaz has a hardness of 8. This means that topaz is harder than garnet and can scratch it. Other minerals with a higher hardness, such as corundum (which includes sapphires and rubies), can also scratch garnet.
