Looks to me like a young candida, has it flowered for you yet?
Flowers on candida are pale pink, with brownish mid-stripe.

Agree for candida. Roemeri, the latest mammillaria is not been sold yet, even the seeds. There are only 4 persons who have this little beauty.

Here is M. candida seedling to compare with your's.
