What is the analogous English word or expression?
We use word "raisin" in figural meaning discribing something special in somebody's behaviour or exterior feature.
For example, У Анны много веснушек на щеках, но это ее изуминка (Ann has lots of freakles on her cheeks, but it is her raisin)

Could you write similar English expression for such cases and give me an example, please)
