I had a commission to make jade earrings with sculpted Irish Setter drops. I decided that given how small they were they needed to be puppies so the head could be large enough for the viewer to immediately see the dog and not just a shape. These took forever and required great detail. I worked from a number of photographs including this one I took when I was visiting the actual puppies. Needless to say the puppies were adorable. It wasn't good light but I got what I needed. I made younger puppies so the head would be more prominent.
They are a little over half and inch for the silver puppies. But this size photo gives a sense of the detail.
