First of all, this is not my own idea of this beautiful necklace! It's drew from jewellery catalogue, to train myself (information is in my profile page if you don't know why).
Brand who made this jewellery is called Ambrosi Gioielli (they are from Italy)
Scanned A4 format
I used graphite pencils from 2H - 4B ,.. and also some color pencils.
