legacies?

i'm awkwardly and somewhat i think inappropriately emotional tonight... my sister's boyfriend contacted me for our grandmother's engagement ring which I inherited and had told my sister that should she get engaged and married before me she could have it, after all i also inherited my mothers engagement ring from my father, who needs two? i'm just like i don't know.. i left it back in MA at what was my grandmother's house now my aunt & uncles because i was paranoid about travelling with it... now i'm entrusting it to my sisters boyfriend to #1 not lose it since he's going to take it back to texas and propose next month and #2 live up to the promise of that ring... its precious to me.. and i know its precious to my sister but i cant help thinking sometimes she'll feel like she won something more than i would... and it feels so wrong to think that... i just ugh.. and i cant give it to him either, other people have to since i cant go back for christmas... i know its the right thing to do and my sister will guard the ring with her life too, but i dont know... lots of things i mean i want to expressly tell them both how much it means to me but not be scolding or i dont even know if its appropriate... wtf? :(
