Halo

Halo

This command allows you to set a selected gem into a Halo configuration.

The halo can be created for the following gem cuts:

Round, Cushion, Oval, Emerald, Radiant, Asscher and Pear

Start by selecting one of the Halo designs available in the RhinoArtisan gallery, or if you prefer to modify the existing design, click the pen icon to enter editing mode. Clicking the edit button will open the command panel for this tool in the Artisan panel, allowing you to customize the halo to your specifications.

Whether you’ve chosen to edit the existing halo or modify one from the gallery, you’ll gain access to the Parameters panel, which is divided into three sections:

1. Metal Profile: This section allows you to customize the metal profile that surrounds the central stone. You can modify the section curve or edit the existing one, adjusting the width and height as needed. You can also control the distance from the central stone’s girdle to the inner edge of the halo, move the halo in the Z direction, and adjust the rotation angle of the section—especially useful for inclining the halo’s gemstones. A Smooth Edges slider lets you fillet the metal profile for a softer transition.

2. Gem Settings: Here, you can define the dimensions of the halo’s gemstones, their vertical position, and the channel where they are set (bright cut and the inner height/width of the channel), plus a toggle to force an even number of gems. You can also choose how the side stones are set—None, Shared Prongs or Scalloped—and add drill holes if necessary. Shared Prongs adds controls for the shared-prong height and diameter, with an option to size them automatically; Scalloped lets you enable V-cutters, boolean cutting and channel removal, with advanced Cutters and V-Cutters expanders for fine-tuning the cutter shapes. Drill holes can be set to None, Round or Quad, with a width and height for the chosen shape.

3. Prongs for the Central Stone: In this section, you can control the prongs that secure the central stone. Adjust the prong diameter, the height above the stone’s girdle, and their position (move in Z and rotation). Additionally, you can extend the prongs for manufacturing purposes if the manufacturing mode is enabled in the Outliner panel. The prong section shape can be set to a simple Circle or a Custom Shape you select from an asset. Choose a Cap Mode of Round (with a Cap Bump control) or Claw (adding gem inside, tip distance, tip height, tip width and a tension slider). Enabling Extend to Bridge connects the prongs to a bridge/gallery structure, with a height and a Curved/Straight mode.
