    Radiant Cut Diamond Engagement Rings

    The best of both worlds. The radiant cut takes the clean lines of an emerald shape and fills it with the kind of fire and brilliance you'd expect from a round diamond; up to 70 facets working together to create a sparkle that's genuinely hard to look away from. At Harmony Jewels, every radiant cut ring is designed and made to order in Hatton Garden, London, in natural and lab-grown diamonds across all metals. Not sure how it compares? Radiant vs elongated cushion — we've got you covered.
