Yellow blackskin agate slabs are very similar to Montana agate and may have bands and or dendrites in reddish brown to black patterns in translucent clear to white agate. They were called blackskins by our suppliers in India, but most have a yellow skin coating with a white layer covering the agate centers of the agate nodules instead of the usual dark rind of blackskin agate nodules . Slab sizes for the yellow blackskin agate will range from 2 square inches to approx. 6 square inches. A minimum of five square inches is considered one sample slab order. The yellow blackskin agate slabs will make wonderful polished stones due to the unique patterns and quality of the agate. Stock 216s. Temporarily out of stock!
