A recent favorite, made for a local couple that I had the chance to work with in person. This set was made from solid white gold and rose gold for hers, and yellow gold and white gold for his. The theme and landscape for each ring was made to be identical, with the finishes of each ring representing a more feminine and masculine theme, respectively. Her ring also features two tiny white stones, above each beach. The mountains are the Palisade range of the California Sierras. More pictures here:
