Deep green and plum, like a vineyard in September. Patches of berry purple float in bottle-green swirls, and the two colors go almost black where they overlap, then flare bright when the sun comes through.

At 8cm, about 3 inches across, this is the smaller friendship ball, sized for a kitchen window, a small apartment or a group of three hung at different heights. Give it to the gardener, the wine lover, or the friend whose favorite color has always been purple. It is small enough to tuck into a gift bag with a card.

Each ball is mouth-blown by artisans in Eastern Europe, so the swirl and the color differ from piece to piece and the one you receive will not match the photo exactly. It arrives in a Sienna Glass gift box with its hanging ribbon and a To and From gift tag, ready to hand over.
