Drusy quartz gems grow slowly over millions of years and are found as the last layer of growth on agate. The sparkling effect is the coating of minute crystals and symbolises energy and security.

The face of each cufflink measures 16.6mm length x 16.6mm height x 6.6mm width. The face of each shirt stud measures 10mm length x 10mm height x 4mm width.
