Moon Mist Cushion Halo Ring
At its heart lies a mesmerizing cushion-cut gemstone, bathed in the distinctive, smoky hue of our signature blue-grey hue. The magnificent center stone is dramatically framed by a precision-set halo of luminous accent gems, amplifying its radiance and creating a bold, eye-catching profile. This delicate circle of sparkle ensures brilliance from every angle. The elegance continues onto the band, which is meticulously adorned with glittering pavé accents.
Specifications: The size of a 1ct and 2ct equivalent cushion-cut centre stone measures at 6 x 6mm and 7 x 7mm respectively. Width of band is 1.9mm and 2mm respectively.
Disclaimer: As each stone comes from a different batch, slight variations in lightness or darkness are natural and expected. Every piece will closely reflect our official product images, but if you prefer perfect uniformity, we recommend proceeding only if you’re comfortable with these natural differences.
