Carat weight 1 61 ct E gt Spread n a with Demo There are two different methods of changing parameter s value First a new value can be entered directly from the keyboard To do this select a chosen parameter value with the mouse type in a new value and press Enter key at the end The other method is to use l buttons that are on the right of each parameter which value can be changed Note that a slider named Step allows to tune the amount by which those buttons change the value For example when the slider is average default positions l buttons change the diameter by 0 1 mm when it is in the Fine position those same buttons change the diameter by 0 01 mm see also Selecting measurement units and parameters to show section that describes how to change presentation of some parameters select one of available measurement units choose one of similar parameters dual parameters etc The parameters on the tab Advanced usually depend on the current cut Examine parameters are available for Brilliant cut diamonds S Shape and cut Parameters quality Appraiser Brilliant 8 ass 200 Proportion Advanced Advanced 2 New Cut Quality Square deviation UE E Step e Star facets ME1X aly DS m Lower facets depth e202 Fine A ough Lower facets length BUE gt sd Girdle alley TEE NI Girdle bezel 272 Culet offset UD S Better group Culet offset azimuth 0 00
