The Imperial eye
Selected beyond the grading report.
For nearly five decades, our family has selected diamonds by looking at the report and the stone itself: cut history, outline, facet pattern, colour, transparency and condition.
Antique diamonds
Cut by hand.
Alive with history.
Old mine cushions are prized for generous facets, distinctive proportions and the warm, intimate light of another era. Each is selected individually for its personality.
