Ronni Kappos Turns Vintage Glass Into Jewelry The latest collection from the Los Angeles jeweler I. Ronni Kappos is handmade from a cache of vintage German glass edged with 24-karat gold, which she fashions into clean, modern shapes with summery bursts of color. These aqua and coral double drop earrings, $127, would be a great accent for a white beach dress, a striped work dress or a tank and jeans shorts. Think of them as an easy way to spruce up without breaking the bank.
