by LightBright » Feb 16, 2019 Hi. I’m interested in how a frosted (bruted, opaque) girdle vs. a polished, or faceted polished girdle affects the look of a colorless diamond. I’ve heard the idea that a frosted girdle can make a darker stone look lighter and was wondering about affects on colorless diamonds. In a colorless diamond, does the girdle play a part in light return. Does more or different light get into the stone with each type of girdle (eg frosted, single facet polished, multi faceted polished) and is that a positive affect? Does the type of girdle affect visible girdle lines, etc.? If a frosted girdle is faceted and polished, would that change how the diamond looks aside from the girdle itself? Also, how much weight is lost by just polishing a bruted girdle into a single facet girdle. VS how much lost in full faceting and polishing? Should you facet or brute a diamond if you are interested in weight retention? Has anyone here polished or faceted a bruted girdle and regretted it, or conversely thought it improved their stone? Thank you for any observations you might have on this!
