Cushion Cut Lab-Grown Diamond Engagement Rings in 18K White Gold Under £4,500
Handcrafted · Hatton Garden, London
Cushion cuts are naturally well-suited to lab-grown diamonds. Their larger facets and vintage character create romantic light play, and the lab-grown price advantage lets you choose a higher carat weight to maximise the cushion's signature charm.
The cushion cut features softly rounded corners and larger facets that produce broad flashes of light rather than the pinpoint sparkle of a round brilliant. Its pillow-like shape evokes romance and vintage elegance, making it a favourite for those who appreciate character over pure brilliance. Available in square and elongated proportions.
