As per etymology, bernstein has derived as follows:
bern>brennen(to burn, to put on fire, to have a light) + Stein(something hard, stone, kernel, rock), thus the word collectively means amber
The above term is of Old High German.
Einstein is also a german term and it has nothing to do with Hebrew.
Hebrew is more similar to Arabic.
B.T.W. thedaffodils, I always recommend learners of English to learn dictionary reading, which includes etymology, orthography, pronounciation gazzetteer and usages of each word.
