BEAUTIFUL 10K DIAMOND AND PEARL RING

This is for a beautiful pearl and diamond 10K gold ring. This was my sister's, and I am unsure of the ring size, and I do not have a ring sizer :( My best guess is a size 6? Box is not included, but it will come with a box to keep the product safe during shipping :) Please refer to all pictures (zoom in and out) as it is part of the description :)
