I realize that this question is mainly for a material item but the first thing I thought of when I read this question was my heart. My heart has been cracked, bruised, sewed up and stitched back together more times than I can count. Yet, it still has this remarkable glow and has managed to stay whole even through all the bull shit life has brought me. So, yes, my heart is my most treasured item. It loves to love and loves life!!!!!
