Jacob & Co. N.E.R.D. White Gold Brain Pendant Chain

This custom-made 14K white gold, rose gold & diamond pendant and matching chain was commissioned in 2005 to celebrate the N.E.R.D. supergroup collaboration between Pharrell and longtime partners Shay Haley and Chad Hugo. White gold, rose gold, white diamonds and pink diamonds frame the N.E.R.D. brain logo, which is set in blue diamonds. The pendant and chain combined weigh in at just over 2 lbs. This piece was preceded by a yellow gold version which Pharrell commissioned in 2004.
