algorithmic modeling for Rhino



This group is obsolete, do not expect support here. Moved to the Peacock's server on Discord:


Generative Jewelry
 is a new discipline in 3d jewelry design which lets you create parametric jewelry, automate production, optimize costs, do much more with much less and create new shapes only possible with the algorithmic modeling and scripting. These tools allow you to create quickly and easily jewelry with Grasshopper :)

Group organization


If you need help using a component, or you need advice on how to do something about jewelry in Grasshopper, you can post a discussion in this group. Tutorials are coming.


These components may contain small bugs, are usually easy to detect the cause and fix them. Please, if you find any, notify me with the ghfile to
If you need the fixed component, I can send it if you ask me. Otherwise, the correction will be added in the next release.


If you think would be useful to change something of a component, you can notify me via email or post a discussion, for example title "Component prongs should have fewer inputs". Consider whether you need to open a discussion or better send me an email.

New components.

If you have an idea for a new component, you can post a discussion in this group. It may be just a wish or be accompanied by a proposed definition. If you do not want to publish the content of the definition, have a private discussion with me via email.

To propose new components, we should follow rules. At the beginning of the title of the discussion, you should put "NCP -" (New Component Peacock)


If you want to participate in the development of Peacock, must share with me via email three new useful components. I reserve the option to choose collaborator. These components will be owned and have their name while 50% of the original script is not modified.
Being developer supposed to know the password of all components. Personally, I would rather share the components as open, but I need to custody my work for now.

Hi Ethan,
update your version of Grasshopper (now is 0.9.0076), will see that the Cleen Tree component has changed.

Hi Daniel,

I've just downloaded the new version of Peacock and am playing around. When I drag either the filigree or variable pipe components I'm getting a prompt for 'Clean Tree' as an unrecognized object. Is this the same Clean Tree as in the Set menu or something else? I'm using GH v.90066. Thanks.

Hi Martin,
of course you can, but it depends on how you have made the stone. If you use Gem Studio you have an input Flip, you can change it with Boolean Toggle component. If you use Gem by Curve you have an input to change the angle (in radians). If you use Cabuchon Studio you need to put the plane in the proper orientation. And besides, you can always rotate any object with native components of GH.

Hi Daniel,

Is there a way to flip the stones?
