“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 Classic Four-Prong Cathedral Lab Grown Diamond Engagement Ring

Timeless, refined and designed to place the diamond at the heart of the ring, the Oval Classic Four-Prong Cathedral Lab Grown Diamond Engagement Ring by Sphere Diamond features an elegant oval lab grown diamond held securely in a classic four-prong setting. The cathedral-style shoulders rise gracefully toward the center stone, creating a beautifully balanced silhouette while allowing the elongated oval diamond to become the focal point.

The simplicity of the polished band complements the brilliance of the oval diamond without competing for attention. Its clean proportions make this design an elegant choice for those seeking a lab grown diamond engagement ring in Bangkok that combines classic fine-jewelry styling with a modern oval diamond.

Classic Oval Cut Lab Grown Diamond

The oval cut is admired for its elongated outline and brilliant faceting. Its graceful proportions can create an elegant appearance on the finger while offering the sparkle associated with brilliant-cut diamonds. This makes an oval lab grown diamond engagement ring an enduring choice for proposals, engagements and milestone celebrations.

Classic Four-Prong Setting

Four carefully positioned prongs secure the oval center diamond while keeping much of the stone visible. The minimal setting allows light to interact with the diamond and preserves the clean, open appearance of the design.

Elegant Cathedral Setting

The cathedral shoulders rise gently from the band toward the center setting, creating an architectural profile that supports and visually frames the oval diamond. The result is a classic engagement ring with graceful height, balanced proportions and a refined side view.
