Cushion Cut Lab-Grown Diamond Vintage Engagement Rings in 18K White Gold Under £4,500
Cushion Cut Lab-Grown Diamond Vintage Engagement Rings in 18K White Gold Under £4,500
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.
Bright, modern elegance at an accessible price. 18K white gold contains 75% pure gold alloyed with white metals such as palladium or silver, finished with a rhodium plating for a bright, reflective white appearance. It offers the elegant look of platinum with a lighter weight.
At £4,500, you can choose a 1ct natural diamond engagement ring in most settings, or a 2ct lab-grown diamond for maximum visual impact. This price point offers genuine luxury without compromise.
Lab-grown cushion cuts are typically 15–25% less than equivalent lab-grown rounds, doubling the value proposition.
Vintage rings with a 1ct lab-grown diamond start above £4,500
At 1ct, even lab-grown vintage rings start above £4,500.
