Although it looks like combing, the pattern is so regular that I suspect it was applied with a specialty roller. My guess is paint with perhaps a thickening additive like sand. I suppose it could be stucco, though I always think of textured stucco looking thicker than this does.

It appears to be a stomped ceiling, done with a tool, and thats why its all in a pattern. Yours is lighter stomped than what I had at the last house, so much easier to paint than mine was. Here is a picture of a stomp brush. the handle can be long or short. Yours could be done with a stippling brush, which isnt as firm a bristle as a stomp brush.

Hi! I think I figured it out. Is it a Basket weave texture? They sell a roller for it. It looks very close to that. Thank you to all who gave me ideas

If you're considering this Basket Weave Texture roller or this roller, the pattern they create is not the same as that on the existing ceiling. The existing ceiling is clearly created manually, not with rollers that create consistent, repeating patterns.
