It's been everywhere lately.
As people realize they can make a neutral (or near-neutral) out of any color by adding grey... we get so many new choices, and sage has been many people's favorite.
Sage looks great in almost every context: modern design, rustic, traditional. It also looks good with all sorts of indoor plants, making it easy to bring the outdoors in.
Of course sage looks great on people, too. The color actually looks fantastic both on those who wear pastels and on anyone who likes earth-tones.
These earrings are some of my current favorites. Those sage-green stones swing freely when you wear them, and the facets on the crystal quartz teardrops sparkle!
