I'm selling off some natural stones I can't use. Please refer to the images for the size. Each square is 10mm. As these are natural stones, there may be variations in the original color, cracks, chips, misaligned holes, size differences, black spots, inclusions, and polishing compound residue. Please understand this before purchasing. Please refrain from purchasing if you are concerned about cracks, inclusions, or chips around the holes. Made in India.
