To personalise your jewellery you can add some red garnet if your loved one was born in January.
Red garnets were the most commonly used gemstones in the Late Antique Roman world, and the Migration Period art of the “barbarian” peoples who took over the territory of the Western Roman Empire. They were especially used inlaid in gold cells in the cloisonné technique, a style often just called garnet cloisonné, found from Anglo-Saxon England, as at Sutton Hoo, to the Black Sea.
Pure crystals of garnet are still used as gemstones. The gemstone varieties occur in shades of green, red, yellow, and orange… it is known as the birthstone for January. -Wikipedia
