By Edward H. Stockwell, London, 1880
Description
The Maker: Crafted by the renowned Victorian silversmith Edward H. Stockwell, who was celebrated for his high-quality "whimsies" and cast novelty items.

The Design: Exquisitely modelled as a naturalistic rose spray, this piece features a fully bloomed rose and a delicate secondary bud on a leafy stem. Unlike standard flat vinaigrettes, this is a three-dimensional "cast" object, giving it a realistic texture and a satisfying weight in the hand.

Functionality & Detail:
The Vinaigrette: One of the petals on the central flower hinges open to reveal a silver-gilt interior and a drill-pierced grille designed to hold a perfume-soaked sponge.
Wearability: The reverse is fitted with an unmarked yellow metal brooch pin and a safety chain attachment, allowing it to be worn as a "tussie-mussie" style fashion accessory.

Condition: Good, The casting remains crisp, showing the fine veins in the leaves and the delicate overlap of the petals.
