Vintage Brooch With Pink Opals

The brooch is a vintage piece featuring a gold-tone metalwork design in a circular, wreath-like shape. It is adorned with five oval, pink opal cabochons and accented with clear and purple rhinestones set in floral and starburst patterns. The brooch measures approximately 2 3/4 inches in diameter. There are markings i can't make out. Google said Lindsor, but thats not their mark. 🤷‍♀️
