We only have a little information about this brooch, which shows a five petal red rose with pale petals inside it, and a red stone centre.
The flower sits atop a heart-shaped element- to me this looks like a vase or pot, with sprays of leaves coming out at the sides. Two bars come from these leaves and join at the bottom, giving the pointed shape of a heart, or even a shield. This is studded with three purple stones.
There is no known provenance for this piece, but it appeared in 2012, FHMJV says, and was worn a few times in close succession. The date suggests it could well have been a jubilee present.
Despite its red and purple tones, we have see the brooch on a variety of backgrounds including blues and pinks.
