Mid 20th Century Leaf Brooch w/ blue and clear stones, heirloom vintage

This is a high-quality vintage brooch, from the mid-20th century. This was my mother's and it is an heirloom, vintage piece. From Claude AI's assessment, and local jeweler. Here's a more detailed assessment: Design: The brooch features a stylized floral or leaf design, which was popular in the 1940s and 1950s. Materials: The metal appears to be silver-toned, possibly sterling silver. The blue stones look like they could be aquamarine or blue topaz. Clear stones are likely rhinestones or possibly crystals. Condition: From the image, the brooch appears to be in good/fair condition with a total of 4 missing clear stones on the right. The piece shows intricate detailing and quality construction. Given these factors, this is estimated to have a value as listed. If it's a high-end costume piece (with glass or crystal stones): $75 - $150 If it features genuine gemstones and sterling silver: $200 - $400. I do not know what the stones are and the far right leaf stem is bent. Each stone is pronged.
