Annoushka - Annoushka's Dusty Diamonds Topaz Ring is a playful and tactile piece. Designed in 18 karat rose gold, 1.60 carat pavé set Blue diamonds surround a 10.50 carat London Blue Topaz stone. Bursting with natural character, the delicate imperfections of the Topaz lend this ring a glamorous, vintage feel. Just as perfect worn with jeans as it is for cocktail hour.
