An excellent cut AAA quality 2.63ct black round diamond is set atop this 4.53ct total weight ring and band set. Surrounding the solitaire are 1.10cts of white round diamonds on the engagement ring and .80cts of white and black diamonds on the matching band. The rings are made in 18k black gold (an advanced electroplating solution of black rhodium with stabilizer is applied to the white gold ring to achieve its dark finish) and they have a 8.6mm width at their largest point. We offer a risk free 30 - day return policy with this magnificent item. It's detailed in our return policy page which can be accessed by clicking the link at the bottom of the page. Accompanying the ring is a full independent gemological laboratory UGL diamond certificate as well as a separate Front Jewelers store appraisal. Both state its characteristics and reflect its appraisal value of $7,395.
