It is a cheap rip off of 'Mandy Lace Silicone Mould'. Available at CakesAroundTown in Australia and Marvellous moulds in the states, but sure if you plug it in to a search engine you will find other countries to buy from.
Oooh thank you so much Cazza! I knew it had to be a replication; thanks for pointing me the in right direction as to where to purchase the original mould.
Thanks so much!
