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.
Our collection of radiant diamond cut engagement rings is selected for buyers seeking a bold, contemporary profile. Each radiant diamond ring is reviewed for cut accuracy, corner protection, and secure mounting to support long-term use. These designs work well as radiant cut engagement rings or as a radiant cut wedding ring when paired with a suitable band. Harmony Jewels focuses on construction quality and reliable diamond grading, offering radiant engagement rings that maintain brilliance, alignment, and comfort over time.
