Hidden Halo

Hidden Halo

The Hidden Halo command builds a small halo of stones set into a channel that sits underneath the center gem, hidden from a top view and only visible from the side or the profile. Select one or more diamonds or gemstones and the command generates a channel ring plus the small stones set into it, all sized and positioned relative to each selected gem. Round and Princess center shapes are supported; Marquise, Triangle and Coffin gems are filtered out of the selection because the hidden halo cannot build a rail around them yet.

The command panel is organized in two tabs: the Channel tab, which shapes the ring that holds the small stones, and the Gems tab, which controls the small stones and how they are set.

Channel

• Mode: Choose the ring shape independently of the center gem’s own outline — Circle, Square or Oval. Square and Oval remember their own X / Y size, so switching between shapes does not lose your settings.
• X Length / Y Length (Square and Oval only): The extents of the ring in millimeters.
• Metal profile: Pick the channel’s cross-section from your profile assets using the preview selector.
• Width and Height: The dimensions of the channel cross-section.
• Distance to gem: How far the channel sits from the center gem.
• Z position: Vertical offset of the channel.
• Rotation: Rotates the channel’s cross-section — 90° is the “hidden halo” orientation, tilting the section and every small-stone plane so the stones face outward instead of up, which is what keeps them out of sight from the top.
• Smooth Edges: A slider that rounds the channel’s corners.

Gems

• Stone shape: The shape of the small stones set into the channel — Round or Princess.
• Gem size: The diameter (or side, for Princess) of each small stone.
• Min distance: The minimum gap kept between adjacent stones.
• Vertical: Vertical offset of the stones inside the channel.
• Bright cut: Width of the bright-cut facet cut around each stone.
• Inner height / Inner width: Dimensions of the channel’s inner opening around the stones.
• Force Even Number: Forces the stone count to an even number so the halo stays symmetric.

Prong settings — choose how the stones are held, with three modes selectable by icon:

• Channel (none): The stones sit directly in the channel with no additional prongs.
• Prongs: Adds shared prongs between the stones — Gem inside, Prong height, Extension for manuf., Distance, an Automatic Prong Diameter toggle, and, when it is off, External Diameter / Internal Diameter to set the prong size by hand.
• Scalloped: Cuts a scalloped bright-cut pattern between the stones instead of prongs. Toggle V-Cutters to switch the cutter shape, Boolean to carve the cutters directly out of the channel, and Remove Channel to strip the channel geometry. Configure the Cutters with Start/End Height and Width, Length, Move in Z, Move Middle in Z, a U Shape / V Shape selector and a Shape Scale slider; when V-Cutters is on, a matching set of V-Cutters parameters appears below.
