Marquise Natural Diamond Side Stone Engagement Rings in 18K Rose Gold Under £2,500

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 marquise cut features a distinctive elongated shape with pointed ends, offering the largest face-up area of any diamond shape for its carat weight. Its boat-like silhouette creates a dramatic, regal presence on the finger and makes the stone appear significantly larger than other shapes of the same weight.

Romantic warmth with a blush of copper. 18K rose gold is created by alloying pure gold with copper, producing its signature pink-blush hue. It offers a romantic, distinctive look that has surged in popularity for engagement rings.

Under £2,500, a 1ct lab-grown diamond engagement ring in platinum or 18K gold is well within reach — with budget left over for a more intricate setting style such as halo or side stone.

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 £2,500 budget.
