Add Frosted Facets

The Add Frosted Facets dialog lets you frost an entire side (pavilion or crown) in one action, adding frosted slivers to all the facets on that side at once.

Opening the dialog

Click Frost Edges in the toolbar (next to Ray Studio). A modal opens with options:

  • Pavilion (checkbox, checked by default): Frost all the facets on the pavilion (the bottom side).
  • Crown (checkbox, unchecked by default): Frost all the facets on the crown (the top side).

Choosing which sides to frost

Most cuts frost only the pavilion — it's the most common choice and a good default. You can also frost the crown alone, or both at the same time. Select one or both checkboxes, then click Add Frosted Edges.

Tip

If you're not sure, start with pavilion-only frosting — it's the traditional look for most brilliant cuts.

Adding frosting

Click Add Frosted Edges. GemDiagram computes and adds frost facets to the chosen side(s). A message at the bottom of the dialog tells you how many frost tiers were added (e.g., "Added 3 frosted tiers to the pavilion").

If a design has no facets on a chosen side (rare, but possible in a custom design), GemDiagram will say "No facets to frost on the selected side(s)" and won't add anything.

Note

Re-frosting replaces: If you frost the pavilion, then later frost the pavilion again (maybe with a different cut), the new frosting replaces the old. The crown's frosting is left untouched — only the side(s) you select get regenerated.

Removing frosting

Click Remove frosting to strip all frosting from the design at once. A message confirms it's been removed (or tells you there was no frosting to remove).

To remove frosting from just one side, use Click-to-frost a facet to manually uncheck individual frost facets, one at a time. For a faster approach, just re-frost the opposite side: frosting the crown replaces any old crown frosting and leaves the pavilion untouched.

Closing the dialog

Click the X button, click outside the modal, or press Esc.

Effect on the 3D view

After clicking Add Frosted Edges, the viewport updates immediately — you'll see the frosted slivers along the facet seams, especially noticeable in Realistic render mode with the stone rotated to catch the light. The frosting won't show up in Solid mode until you toggle to Realistic.

Exporting with frosting

Frosting is baked into the design file:

  • Save: Downloads the design as a .facet file including all frosting.
  • Export → PDF: The cutting report shows frosted facets as a distinct tier tier (or multiple tiers, one per cone-angle ring).

See Frosting in import & report for how frosting appears in imported files and reports.
