San Carlos Moss Agate Rough Chunk! Petrified Wood Slab and the drip formation isSan Carlos Agate is a stunning moss agate from near San Carlos, Mexico. This is a somewhat newer discovery, with gorgeous rough just now hitting the market. So far with our cutting, we have been greatly enjoying this stone, as it has some well defined moss with gorgeous coloration. It also appears it will take a nice polish. Photos are generally taken wet to simulate a polish. Weight: Approx: 1 lbs 5. 1 oz Measurements (inches longest approx): 3. 7 x
