Antique diamonds are not understood by memorising a grading table. Their appeal lies in the relationship between outline, facet architecture, depth, light return, age and individual character.
Dealer knowledge for collectors and private jewellers
This library explains how experienced dealers look beyond a headline grade. Each guide connects practical knowledge with real stones from the current collection and with the questions that should be asked before an inspection.
- Historic cutting styles and how they differ
- Proportions, face-up character and light behaviour
- Fluorescence, diamond type and laboratory documentation
- Matching antique stones for pairs and modern settings
- Inspection, independent verification and private acquisition
