Victorian Diamond Garland Brooch “en Tremblant”

A stunning late Victorian garland brooch set in silver-on-gold, designed with an Old Mine-cut diamond flower motif set “en tremblant” at the centre, surrounded by grain-set Old Mine-cut diamond foliate sprays.
“En tremblant” is a French term – meaning “to tremble”. It was first used to describe 18th and 19th-century jewelry where parts of the diamond set pieces were attached to a trembler to create movement in the jewel when worn. Brooches mounted in this way were particularly effective in reflecting the scintillating fire of candlelight.
The brooch is set to reverse with a pin and roller clasp fitting. The total diamond weight is approximately 4.55 carats, mostly H-J colour (assessed), SI clarity (assessed). Measurements: 5x5cm. Weight: 17.5g.
