The Diamond Quality™ Document Measurement The AGS Laboratories uses a Sarin DiaMension machine to obtain millimeter measurements and the proportion information about each diamond. Round Brilliant millimeter measurements are expressed (minimum diameter) - (maximum diameter) x (depth). All other shapes are always expressed (length — top to bottom) x (width — left to right) x (depth). Length is usually the largest measurement, but some shapes are wider than tall. Therefore, you could see measurements that look like this: 3.80 x 4.48 x 2.60 mm. |
