Cushion Cut Natural Diamond Side Stone Engagement Rings in 18K Yellow Gold Under £2,000
Cushion Cut Natural Diamond Side Stone Engagement Rings in 18K Yellow Gold Under £2,000
Natural diamonds are formed 150–200km below the Earth's surface under extreme heat and pressure over 1–3 billion years. Each natural diamond is unique — a one-of-a-kind creation of nature. For those who value rarity, tradition, and the knowledge that their diamond is a geological marvel billions of years in the making, a natural diamond is the ultimate choice.
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.
Warm, timeless, and universally flattering. 18K yellow gold contains 75% pure gold and has a rich, warm tone that has been the traditional choice for fine jewellery and engagement rings for centuries. Its natural colour will never fade or require re-plating.
Under £2,000, you can find a 1ct lab-grown diamond engagement ring in your choice of metal and setting style. This price point represents the most popular budget for lab-grown diamond engagement rings — genuine luxury without compromise.
Side Stone rings with a 1ct natural diamond start from £3,711
Natural diamonds at 1ct are priced from £2,386 for the diamond alone. Combined with a side stone setting, the total exceeds your £2,000 budget.
