Please help me find my engagement ring, I am devestated to have lost it, particularly as it is all my fault. We were filming my new series "Kirstie's Home Made Home" in London on Tuesday 24th February; I was learning how to make a mosaic, so took it off and put it in my pocket. When we stopped for lunch, I went to buy sandwiches from Marks & Spencers in Mare Street, Hackney, London E8. Having retraced my steps and spent ages tearing the car apart searching, it must have fallen out of my pocket in or near the shop.

My boyfriend, Ben gave me the ring, he wanted to mark the birth of our first child, Bay, it is also my engagement ring and means the world to me. So, I am desperate to get it back so am offering a REWARD of £1,000 for its safe return.

The large stone in the centre looks like a ruby, although very similar, it isn't. It is big and chunky, so could be mistaken for costume jewellery, the ring has a central stone that is a 33 Carat Spinel (looks like a ruby) surrounded by diamonds. If you are in Hackney, keep an eye on the pavement or on the floor in Marks & Spencers in Mare street , Hackney , London E8. By now it could be anywhere, quite possibly someone has picked it up thinking it is of no great intrinsic value. The sentimental value to me is huge; I am determined to get it back, please help me.

If you know anything or think you might have seen it, Please contact me through this website; remember, it's quite possible that whoever has it now, is wearing it in all innocence, so has nothing to fear by coming forward.
