I have a full size wood mantel above reddish brick fireplace, what to put there?

i have a reddish, cranberry ,off white boarder-with sage green in background with a small amount of black on bottom of boarder. walls are wheat, couch camel, chair plaid with reds,greens,pinks,yellows,orange sounds bad i know , it's nice. my floor is laminate walnut in color. right now i have a picture of a white flower with greens surrounding just the flower, background of picture is like a crannberry d, matting is dark green with a queer black frame. i'm so lost as to what to do, been trying to decide for 2 years now, sad i know!. anyway tried green big clock, tried 3 black mirrors. my house is a split and upon entering kitchen my family room is the first thing you see with fireplace the main focal point, so i wanted something with a wow! i'm a loser with decorating. ps. thankyou so much denise
