Stone fireplace surround

Old fireplace surround taken out of our house when renovating. It looks to be black slate with painted marble finish. Also have the hearth in polished black granite to go with it. Some of the paint effect has worn off. Could look good cleaned down and returned to satin black slate for a contemporary look in an old cottage. Need gone as sat in shed for to long. If interested let me know or make an offer as I won't keep it much longer and it would be a shame to scrap it. Thanks for looking
