Are they carved stone or cement? If carved stone, have they been repaired? The lady looks like she has at least some cement at her feet. If they both have too much patina to tell, you could try cleaning the bottoms. If they are cement, I doubt they are worth much, but I'm no expert. If they are carved stone, then you might have something of value.

Thank you for your comment. Yes they are apparently stone. There are no seams on any of them.

I think they look like they could be valuable. Can you take pictures to an antique dealer to see what they might say or if they have someone who could appraise. I wouldn't give away or sell till you know more. Looks like something you might see on Antiques Roadshow. Are they heavy?

Yes they are very heavy and definitely stone
