The front of the brooch is enamelled in matt opaque white with spots of yellow, green and blue. A series of silver buds are cold fixed to the front of the brooch so that they have some movement. The buds are also vitreous enamelled in transparent yellow, green and blue with a glossy finish. The brooch has a double pin to support its weight and measures approximately 5cm in diameter.
The brooch has a hallmark rom the Birmingham Assay office and comes packaged in a Miranda Sharpe jewellery box.
