Diamond brooch, late 19th century designed as a stem of leaves and buds set throughout with rose-cut diamonds, accented by an 'En tremblant' flowerhead at the centre, mounted in silver and gold, length approximately 2.48 in. Accompanied by a fitted presentation box.
- En Tremblant - En tremblant is a French term meaning "to tremble". It was first used to describe 18th and 19th century jewellery where parts of diamond set pieces were attached to a trembler to create movement in the jewel when worn. It's most common use was in brooches, especially for jewellery incorporating floral motifs or butterfly or dragonfly wings. There was a revival of the technique in the 1950s and 60s by Bulgari, and their jewellery became very fashionable with Hollywood stars.
- Rose Cut - A flat based cut for a preious stone, leaving the surface covered with triangular facets, usually 24 in total.
It was introduced in the 15th century and popular during the 16th and 17th centuries.
The rose cut was the most popular form of diamond cut until the discovery of the brilliant cut at the end of the 17th century, after which its use declined.
