We look at these six points in front of you, then we make a firm offer.
Weight, colour, clarity, quality of the cut: for a Harry Winston ring, this is the essential. We weigh it and read it in front of you.
Often in platinum — PT950 mark —, the piece is signed “HW” or “Harry Winston” and numbered.
For a Cluster, each pear, marquise or round diamond counts, and the workmanship of the setting as much as the stones.
Reference, serial number, stamped guarantee card: a watch is read with its papers, but is examined without them too.
A worn claw, a tired clasp do not prevent a sale; we value the piece as it is.
They add value to the piece, without being essential.
