The engagement ring is a piece of jewelry your partner will wear every day for the rest of their life, so get a sense of what they really love. Snap photos of the jewelry they wear every day, take a peek at their Pinterest boards, or ask a close friend or family member to help narrow it down. As for jewelers, get recommendations to make sure you’re purchasing from a trusted store with great reviews and service. Last but certainly not least, find out their ring size. If it’s not a secret, just ask.
