Piaget

Piaget Sunlight

The sun as a disc of gold rays, each segment engraved, brushed or polished, around a halo of diamonds.

Bouton d'or

Van Cleef & Arpels

Bouton d'or

Little discs of gold, each with a stone at its centre, massed in rows and rings like the head of a buttercup.

Sunlight from Geneva, sequins from 1930s Paris. Piaget Sunlight splits the sun into segments of gold, engraved, brushed or polished, around a diamond halo, a motif that began with the Sunlight Journey high jewelry of 2017. Van Cleef & Arpels' Bouton d'or, revived in 2016, gathers polished yellow-gold discs with stones at their centres into the head of a buttercup. Piaget varies the texture within one form, and Van Cleef & Arpels repeats one form many times.
