A tiara encrusted with 178 Rio Tinto’s rare Argyle pink diamonds is one of the rare exhibits at the Masterpieces London Fair, a showcase of such unique pieces. The tiara is displayed by jeweller Asprey.

Its design sensibilities narrate art from the bygone era shaped in contemporary style, and shows off the varied colours, sizes and shapes of Argyle pink diamonds. The tiara, rare Argyle pink diamonds and pink diamond jewellery are part of the Asprey showcase at Masterpieces, London being held from June 24-29, 2010.
