Help needed with beautiful ceramic cups

Hello folks! I hope you are safe and healthy

I am back and in need to identify the origin of these cups I got from my late uncle. They seem old, but such beautiful cups in my opinion. I just can't find anything similar except Russian Gzhel cups, which I don't think these cups are from. I own Gzhel porcelain too and their style is different.

There is a mark under the cup, but mostly faded. Maybe someone has seen a mark like this?

Thank you in advance!

Erik

 

Very pretty! Below is an enhanced image of the mark in your photo if it helps!

 

And the other.

 

Thank you guys for help. Still can't figure it out

 

German? Eastern European, like Poland, perhaps?

 

Yep, that is what I am thinking too. Too bad I can't figure out the mark

 

The red mark made me think Russian. I can find similar cups by Gzhel, but I didn't find this mark anywhere. Maybe someone can tag Natalia? I'm sorry, I just noticed I repeated what you already said.

 

Yes, you might be right Who is Natalia? I need her hehe

 

Yes--Natasha--I am a doofus. Thanks.

 

I am very sorry but I do not know. Never saw such a mark. Do not think it's Russian
