In an ongoing trend, another jeweler has launched an eco-friendly jewelry line. Gary Ptak's new Conscience Collection is a line of designs featuring lab-grown diamonds and gemstones and recycled metals. The minimalist designs include rings for men and women, earrings, bracelets and pendants and are made in 18K gold, palladium and platinum (80% of which is recycled). All the pieces are made in the U.S.
