“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❤️”

Oval Graduated Side Stone Lab Grown Diamond Engagement Ring in Yellow Gold

Elegant from every angle, this Oval Graduated Side Stone Lab Grown Diamond Engagement Ring by Sphere Diamond features an oval lab grown diamond center stone framed by graduated round diamond side stones. Set in warm yellow gold, the design combines the graceful proportions of an oval diamond with additional brilliance across the shoulders of the ring.

Rather than a traditional pavé band, individually set round diamonds graduate in size away from the oval center stone. This creates a beautiful transition from the center diamond toward the polished yellow gold band while keeping each side diamond visually distinct.

Oval Lab Grown Diamond Center Stone

The oval cut is loved for its elongated silhouette and brilliant appearance. Its graceful proportions create an elegant focal point on the finger while offering a distinctive alternative to the classic round diamond engagement ring.

Graduated Round Diamond Side Stones

Round diamonds are individually arranged along both sides of the center stone, gradually decreasing in size toward the band. This graduated side-stone design adds sparkle and visual width around the oval diamond without covering the entire band with diamonds.

The spacing between the side diamonds allows each stone to remain visible as an individual element, giving the ring a refined and dimensional appearance when viewed from the front and side.

Yellow Gold Engagement Ring

The warm tone of yellow gold creates an elegant contrast with the bright diamonds. A polished lower band keeps the design clean and timeless while allowing the oval center diamond and graduated side stones to remain the focus.
