Diamonds and Gemstones

Gem Studio

The Gem Studio command provides a comprehensive solution for creating gemstones in various popular cuts within the RhinoArtisan software. This command offers a streamlined and efficient approach to gemstone design, making it a powerful tool for jewelers. Below are the essential features and functionalities:

Selection Options

The Selection section allows users to position their gemstone with a high degree of flexibility by offering multiple placement options:

In the CPlane: Adds a gemstone with the specified parameters to the center of the viewport, perfectly aligned to the construction plane (CPlane).
On a point: Adds a gemstone at the selected point by clicking in the viewport. This allows for precise placement of gemstones at any predefined location.
On a surface: Adds a gemstone with the specified parameters on the surface selected by clicking. The gemstone will align with the surface’s curvature or orientation for seamless integration.

This flexibility in placement ensures accurate integration of gemstones into your designs, whether you’re placing them in specific positions or aligning them to complex surfaces.

Gem Materials

Offers a range of gemstone materials, each represented by their corresponding color. This feature allows users to visualize their designs with material colors, ensuring that gemstones match the overall aesthetic of the piece.

Note: These materials are used primarily for design purposes. When preparing for rendering, it is essential to use the appropriate materials from the Render and Animation panel to ensure that the gemstones have the correct appearance in the final render.

Parameters Tab

Carats: Determines the gemstone’s weight and size, based on standard carat measurements. When the command is opened, the default material is set to Diamond, with the carat weight set to 1 ct and a diameter of 6.50 mm. If the material is changed, for example, to Ruby, the carat weight will adjust to reflect the density of the selected material. A Ruby with a brilliant cut and a diameter of 6.50 mm would weigh approximately 1.13 ct.

Diameter: Controls the width of the gemstone at its widest point.

(Z) Depth: Adjusts the height or depth of the gemstone from the culet (bottom point) to the table (top facet).

Alignment: This option aligns the gemstone to the center of the CPlane based on the chosen alignment option:

Girdle: Aligns the gemstone so that the girdle (the widest perimeter) is centered on the CPlane.
Table: Aligns the gemstone so that the table (the flat top facet) is centered on the CPlane.
Culet: Aligns the gemstone so that the culet (the bottom point) is centered on the CPlane.

Move in Z: This option allows you to move the gemstone along the Z-axis.

Editing several gems at once

Select several gems before opening Gem Studio, or add them to the selection while it is open, and the panel edits all of them together: the parameters show the last gem selected, every change goes to the whole selection and a single undo step takes it back. Catalog gemstones and certified diamonds become editable gemstones the moment they are selected. The Edit command opens Gem Studio for any loose gem; the stones of a setting are edited from the setting’s own command.

The Unify selected gems toggle, at the end of the Parameters section, decides what a change does when the selected gems differ:

On: every selected gem becomes the gem shown in the panel — same cut, sizes and material.
Off: only the value you edit is applied to each gem, which keeps its own cut, sizes and material. Change the material of twenty stones of different sizes and each one keeps its size; change the carats and each one grows in its own cut.

With the Gem Studio command, jewellers can efficiently create and position gemstones, ensuring accuracy and consistency across their designs.
