Historically, there is a big difference between Russian and Russian Jew. Jews were not included in Russian society. They tended to have small all-Jewish villages that were in constant danger of attack from the larger society. Most contact with the larger Russian society was anything but pleasant (pograms). Male Russian Jews were required to serve 20 years in the Russian army (with the exception of the eldest son who had to carry on the family farm and care for aging parents). They rarely survived that 20 years (by design) and it helped keep the Jewish population down by removing most of the young adult males.
I would not expect a great deal of Russian accessories or clothing. Russian Jews were basically an entirely separate society within Russia.
Historically, the most common combination for a Russian Jew of that period would be brown hair (dark) and brown eyes. Auburn, black, lighter brown and red hair would all be more common than blond. Curly hair was also very common. Gray or hazel eyes are possible, but Russian Jews tended to be more closely tied to the Middle East than the larger Russian society so they tended to be a bit darker in coloring.
I'm not saying AG has to go with the most common combination, but historically speaking blond would not be at all representative of Russian Jews. Actually, a Russian Jew could look a lot like Ruthie which may be one reason AG would take some liberties.
