Navy cashmere scarf with red piping

I lost my navy blue cashmere scarf last night around 7pm near the Scott Monument on Princes Street in Edinburgh. It's a Marks & Spencer scarf, about 180 cm long, super soft, with a thin red piping along the edge and a tiny white monogram 'MC' stitched near the left corner. There's a small moth hole near the fringe, but otherwise it's in good condition. It was a gift from my mum, so it means a lot to me and I really need it back.
