The Stones
The focal engineering point of this ring is a 1.28-carat cushion-cut lab grown diamond, displaying deep yellow saturation classified within the fancy intense tier. This center stone is independently graded by the International Gemological Institute (IGI) with a VS2 eye-clean clarity profile and Excellent cut-grade symmetry. To maximize the stone’s natural dispersion and vivid color, it is paired with 52 round brilliant accent lab grown diamonds totaling 0.48 carats. These accents feature an EF colorless range and premium VVS clarity, creating a high-contrast boundary that optically expands the visual footprint of the center cushion cut.
The Setting
The setting employs a specialized hybrid engineering framework. Four low-profile 18K yellow gold prongs anchor the center cushion stone’s corners, integrated into an inner yellow gold rim that deepens the warm hue of the diamond’s pavilion. This inner assembly transitions into a white gold cut-down pavé halo, which minimizes visible metal to create an unbroken field of accent reflections. The ring is built with an elevated cathedral gallery supported by diamond-set split wire struts, allowing maximum light entry from underneath the stone to drive internal refraction while ensuring the setting sits balanced on the finger.
Metals and Finish
Constructed primarily in 18K Two-Tone Gold (750 purity stamped inside the band), this piece utilizes a deliberate metallurgical arrangement. The central basket uses 75% gold alloyed with silver and copper to retain rich yellow tones under the fancy color stone, while the shank and outer halo are rhodium-plated 18K white gold for high reflectivity. With a gross weight of 4.64 grams and a net metal mass of 4.29 grams, the 1.8mm rounded band provides excellent structural integrity for active daily wear while maintaining a slim, contemporary profile on the hand.
