I stumbled on Ambre & Louise when researching the bottle for the annual limited edition Guerlain Muguet perfume. Each year, they work with a different firm to reinterpret the bottle, and this year’s has a silver overlay with lily of the valley (the predominant green note in the fragrance).

They also do a range of other objects, including jewellery, much of which has a naturalistic theme. This elderberry pin is made of gold plated metal (they don’t specify what it is), and sells for €249. A smaller version is also available.
