There's something quietly irresistible about a cushion cut diamond. The soft corners, the gentle way light moves through it; it's a shape that feels both timeless and deeply personal. At Harmony Jewels, our cushion cut rings are made to order in Hatton Garden, London, in everything from sleek solitaires to pavé and halo settings, across yellow gold, white gold, rose gold and platinum. Available in exceptional natural and lab-grown diamonds — each one made to feel like it was designed with one person in mind. Because it was.














Our cushion cut engagement rings are selected for buyers who want visible presence without sharp edges. Each cushion diamond ring is assessed for cut precision, facet alignment, and setting security to support long-term wear. These designs are suitable as a cushion cut engagement ring or paired as a cushion wedding ring, depending on styling preference. Harmony Jewels focuses on structural durability and refined finishes, delivering cushion engagement rings that hold brilliance, comfort, and alignment over time.
