The 4Cs
Diamonds according to Giuliano Capogrossi Colognesi:
Most diamonds in the designs are either described as “small” (No less than 0.50 carats in weight) or “large” (Aprox. 4 carats in weight). This is because 0.50 carat diamonds will be 5mms in girdle diameter and will be used where the design calls for small diamonds. As diamonds weigh more their girdle diameter (and consequently their apparent face up view size) becomes less predictable, but as a general rule 4 carat diamonds will be 10mms in diameter and will be used when the design calls for large diamonds. Diamonds these sizes are not rare and can be quickly sourced.
A few designs call for a single large solitaire or colored diamonds. In this case diamond features will be discussed with each customer.
