Victorian Blue Butterfly Wing Bar Pin Brooch Rainbow Moonstone Look Close Back

This is beautiful 🩵 stunning colour from the butterfly wing, similar to rainbow moonstone. The condition is great considering the age. The stone measures approx 2x1.5cm. The closure is nice and secure.

It is silver, tested, but not hallmark, some sort of mark is on it,but not clear hence I sell it as white metal.Many jewellery from the past weren't hallmarked. The bar measures approx 6cm. Sweet piece. Thanks for looking:-)
