I was commissioned to make an 18th present for a science nerd. They requested an atom pendant. Since it was an 18th Birthday present, I decided to make the 18th element on the periodic table – Argon. This piece is atomically correct, well, in terms of the number of electrons. I made the electrons quite subtle on the piece. The ball in the centre representing the nucleus is 9ct yellow gold, as is the electrons. The shells (rings) are in solid sterling silver.
