Designer Nora Kogan took the name of her line, St. Kilda, from the Australian neighbourhood in which her parents settled, after they left, Odessa, Ukraine. She now lives in New York. This sterling silver ring, enamelled in acid green and accented with a yellow diamond, is part of her enamel range. She also does lovely wedding/diamond pieces.
Bottega Veneta used scarabs and scorpions as their theme last fall, and their jewellery (mostly sterling silver and enamel, too) was in the thousands. This is USD $895. There is a gold and diamond version on the splash page for the web site, but I was unable to locate it on the site. It was stunning.
