“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❤️”

3 Carat Cushion Cut Hidden Halo Lab Grown Diamond Engagement Ring in Yellow Gold

Make a striking statement with this 3 Carat Cushion Cut Hidden Halo Lab Grown Diamond Engagement Ring in Yellow Gold by Sphere Diamond. Designed around an impressive 3 carat cushion cut lab grown diamond, this engagement ring combines a clean solitaire-inspired appearance with a refined hidden halo and a distinctive Euro shank.

The cushion cut center diamond features a softly squared silhouette with rounded corners, creating a beautiful balance of brilliance and romantic character. Warm yellow gold provides an elegant contrast against the bright diamond, while the hidden halo adds an additional layer of sparkle beneath the center stone.

3 Carat Cushion Cut Lab Grown Diamond

A 3 carat cushion cut creates substantial finger coverage while maintaining an elegant and balanced appearance. The cushion shape combines softly rounded corners with a broad face-up profile, making it an excellent choice for those seeking a distinctive alternative to a traditional round diamond engagement ring.

Hidden Halo Diamond Setting

A delicate hidden halo of diamonds is positioned beneath the center stone. From the top, the design maintains the clean appearance of a classic solitaire engagement ring. From the side, the hidden diamonds reveal additional brilliance and highlight the elevated structure of the center setting.

Yellow Gold Euro Shank

The ring is finished with a distinctive Euro shank, featuring a subtly squared lower profile rather than a completely rounded band. This architectural detail gives the ring a contemporary character and complements the substantial presence of the 3 carat cushion cut center diamond.

The warm tone of yellow gold creates an elegant contrast with the brilliance of the diamond, resulting in a design that feels both timeless and modern.
