Garnets are the perfect gemstones for those at the intersection of beauty, history and affordability. A rich, dark garnet sets off cool skin tones and brown hair, while a rose-coloured garnet will bring out the sparkle in blue and hazel eyes. These stones are so beautiful, they were highly prized in Ancient Rome, where they were placed into the signet rings of important citizens. With options that start well within £100, you’re sure to find the one that makes you feel like a million bucks.
