“After experiencing 5-6 jewellery stores with exceptional service, I thought it couldn’t get better and sure enough it did!! The staff at Sphere Diamond were nothing short of amazing, kind and so so patient with our questions on the quality of the jewellery. When we ended with our purchase, the overall experience was so overwhelmingly satisfying. The jewellery is absolutely stunning and so is the quality!! Would definitely recommend this as a go to jewellery shop❤️”

Roselle Oval Cut Diamond Side Stone Lab Grown Diamond Engagement Ring

The Roselle Oval Cut Diamond Side Stone Lab Grown Diamond Engagement Ring by Sphere Diamond is a romantic interpretation of the classic oval engagement ring. An elegant Oval Cut Lab Grown Diamond takes center stage, surrounded by delicately arranged diamond side stones that create a graceful, luminous silhouette.

The elongated oval center diamond is secured in a classic prong setting to showcase its shape and brilliance. On each side, a carefully arranged composition of smaller lab grown diamonds adds dimension and sparkle while naturally drawing attention toward the center stone.

Unlike a traditional pavé engagement ring, the Roselle design uses individually defined diamond accents around the shoulders of the ring, creating an elegant transition from the center diamond to the polished band. The result is a distinctive engagement ring that feels romantic, refined and beautifully detailed from every angle.
