Diamond guarantee information

Occasionally we will use “minimums” to describe the specification of a particular diamond. Where we do so, that diamond’s specification may exceed and improve upon the information listed, but will not fall below it. For example, a diamond listed with colour minimum “H” may be a “G”, but not an “I”. We ensure this through the application of an independently audited sorting and checking procedure, led by qualified diamond graders.
