Vintage Moira Plique A Jour Diamond Ruby Frog On Leaf Brooch With Box

Now this is truly special! An outstanding vintage Plique-à-jour frog and leaf brooch, crafted by London designer “Moira Fine jewellery” in the late 20th Century. The sweet silver frog is depicted with legs outstretched across a large silver and 18ct gold leaf, with pink cabochon ruby eyes at the head and a dazzling array of brilliant cut diamonds encrusted across the entirety of its body. 

The detailed Plique-à-jour enamelling has been expertly applied around the leaf’s veins and fades gently from green to yellow on the front, with pink and blue hues on the reverse. It’s fitted with a double pin at the back, secured with a locking trombone catch and is decorated with further diamonds around the edges and down the stem, with larger brilliant cuts dotted across the top, depicting dew drops (approx. 8ct total).  

Plique-à-jour is French for "letting in daylight" and is a technique in which enamel is applied with no backing, allowing the light to shine through the translucent layer and create a wonderful stained glass window effect. 

This is a one-of-a-kind vintage novelty brooch, showcasing exquisite enamelwork and twinkling diamonds. It’s all in pristine condition and is complete with the maker’s mark on the back and a large box to store it in, lined with cream velvet and silk within, and a grassy green velvet on the outside.   

We recommend you insure for £10,300. We can provide a written Valuation on completion of the sale.
