My favorite Bone China

I got these items from My sister-in-law recently. She said she got them from My Mum who died over 14 years ago. They consist of 6 miniature cups and saucers plus a sugar bowl with lid. Japan is written on the bottom. Also there is set of six mother of pearl handled knives and forks with the box. Written on each it says Duchess, Sheffield England on the box it says LB 356 Information and maybe value would be good. Want to give to my Eldest Granddaughter. I also have Two statues that I brought 2nd hand in 1993 for my parents that a made in Italy. Each on is 5 kgs. and stand about 18 inches tall. Male and Female.
