GirdledSection class is part of

You can choose either knifeedge girdle la Tolkowsky or real girdle between and percent at the thin parts.

DiamondDimension. exe is Win32 console application that calculates the lengths of all of the edges of perfectly symmetrical diamond. The longdashed curves in figure show diamonds whose thin parts of the girdle are of their diameter at the mains. If you want to try unusual values, please use different program, like CrossSection or GirdledSection . You can choose to see just the results, or see the stepbystep calculations. The differences are similar to Tolkowskys rounding error. Caution The model breaks down at both ends of the range.

The differences are similar to Tolkowskys rounding errors. The simulations suggest slightly different pavilion angles. They are medium for mm to mm diameters. To keep constant total girdle thickness at the thick parts mains, small diamonds need larger percentage girdle thickness. My girdle article shows how adding girdle changes Tolkowskys Diamond Design.

Extrapolating to larger pavilion angles makes fisheyes. These diamonds are fragile, because of their thin girdles. The thin curves and the dashed curves show How Adding Girdle Changes Marcel Tolkowskys Diamond Design. My model assumes that the thickness of the girdle and Girdle Wave reduces the brilliance of the diamond. CrossSection. class is part of Diamond CrossSection. My girdle article shows how adding girdle changes Tolkowskys Diamond Design. These girdles are nearly ideal for large diamonds.

DiamondDimension. exe is Win32 console application that calculates the lengths of all of the edges of perfectly symmetrical diamond. My girdle article shows how adding girdle changes Tolkowskys Diamond Design.

These diamonds are fragile, because of their thin girdles. My editors notes to Diamond Design correct Tolkowskys rounding errors, and show how the best crown angle and table ratio that correspond to your pavilion angle angle and girdle thickness. My girdle article shows how adding girdle changes Tolkowskys Diamond Design. They are medium for mm to mm diameters. To keep constant total girdle thickness at the thick parts mains, small diamonds need larger percentage girdle thickness.

Tolkowskys rounding error on the table size seems to go in the wrong direction. These diamonds are fragile, because of their thin girdles. GirdledSection. class is the Java program that calculated the thin curves and dashed curves in Figure The longdashed curves in figure show diamonds whose thin parts of the girdle are of their diameter at the mains.
