Did Bella ever found out that the little दिल that Edward gave her was actually a diamond?

Yes, she found out from alice

no, she found out from Jacob, when he noticed the little charm he कहा "a rock" & that reminded her of what Alice wanted to say before Edward cut her of, she कहा something about "what's one और diamond? my point is, he already got one on..." then Bella ended the sentence द्वारा adding "you" at the end, so what Alice wanted to say was; "What's one और diamond? my point, is he alredy got one on ...you" çe ça

yup yup !!

आप tell me i dont know either i think she found out from alice
