These books are by Maurice Galli, Dominique Riviere and
Fanfan Li. The first in the series is called 'The Art of Jewellery
Design' and would be the best one
Where would you find this book? I checked Amazon but not
there. The other book that I liked was "Practical Jewelry
Rendering" by Tim McCreight...very good techniques and exercises.
If you search Amazon using Fanfan Li, all three books come up. I
ordered mine through them some months ago, the books are by special
order and were certainly worth the wait.
As someone else mentioned, the book covering rings and earrings has
the most useful on rendering. The others don’t go into
details and stages of drawing, instead they generally present you
with finished drawings.
