DIAMOND & MOISSANITE CARAT SIZES SHOWN ON THE HAND

Below are images of incremental carat sizes in every center-stone shape, shown on a hand model with a ring size of 5.75. Each stone is set into a ring and please note these are only close approximates as center-stone dimensions and length/width ratios can vary on stone by stone basis. At Lauren B we aim to give our clients the most well cut stones that achieve a balance of large face-up dimensions and high levels of sparkle.
