Vintage in origin, extraordinary in effect. The Asscher cut was born in the Art Deco era and has never lost its allure: its square shape and deep step-cut facets creating that mesmerising hall-of-mirrors brilliance that no other diamond quite replicates. It's a cut for someone who appreciates history, craftsmanship, and a ring that turns heads for all the right reasons. At Harmony Jewels, every Asscher ring is made to order in Hatton Garden, London, in natural and lab-grown diamonds, from classic solitaires to elegant trilogy designs.














Our collection of Asscher cut diamond rings is designed for buyers who prefer a bold yet refined design. Each Asscher engagement ring is carefully evaluated for facet alignment, corner protection, and overall polish to ensure durability and brilliance. These designs are suitable as engagement rings or as wedding rings when paired with matching bands. Harmony Jewels focuses on craftsmanship and quality grading, delivering Asscher cut engagement rings that maintain alignment, sparkle, and comfort over time.
