The prize for the most arresting catalogue cover of the season thus far must go to Adam’s of Dublin. This ‘make-you-look’ image for the September 18 catalogue includes both a Victorian diamond pin, designed as a flowerhead with old brilliant, cushion and rose-cut stones mounted en tremblant (estimate €1800-2200), and a dress ring by Margherita Burgener, formed as a flower with a cabochon green tourmaline centre and textured purple titanium petals (estimate €2000-3000).
