Founded by Laurence Graff in London in 1960, Graff is renowned for handling some of the largest and finest diamonds ever discovered. The house controls its stones from rough to finished jewel, and a Graff piece is, above all, about exceptional diamonds — which is exactly where most of its resale value lies.
What is Graff jewellery?
Graff is a London high-jewellery house defined by exceptional white and fancy-coloured diamonds — solitaire rings, diamond necklaces, earrings and bracelets, plus signature lines like the spiral and butterfly motifs — in platinum and 18ct gold. Pieces are signed Graff, often numbered, and the important stones come with GIA or Graff certificates.
