American Standard Ring Sizes range from 7 to 18, with each size incrementing by approximately .025 inches. However, some manufacturers utilize a system that adds 1-2 millimeters to their ring sizing scale due to slightly thicker metal and a tighter fit on the hand. Gold's density is approximately 19.3 grams per cubic centimeter (g/cm^3). 5 grams divided by the density of gold will equal its volume in cubic centimeters. We know that gold has a density around 0.0322 oz/cubic inch so this weight would be 1/8th ounce. We have 7 total increments in this size range, meaning we must calculate the actual length in each of these ranges by dividing by the ratio of .5mm/inch, resulting in an increase of half a millimeter with each incremental measurement on our American Standard scale, equating to 2.5 millimeters for all of them combined. Since your question specifically mentions metric and standard system sizes let's just look at your gemstone's measurements instead! Three-Dimensional models have been prepared which can be used to machine custom pieces or adjust their dimensions if needed - these images show each stone in perfect detail ready for immediate 3D printing or CNC work as they were made from the very start with precise accuracy
