algorithmic modeling for Rhino



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 :)

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, Daniel

ribbon-surface.3dmI am a fine jewellery designer, and I tried to use this plug in for paving stone, each stone doesnt have distance or only under 0.1mm,

to surface edge there should be at least 0.3mm distance,  

I want to ask the function for pave on surface, 

is not possible to pave on surface on the surfaces like this?

I tried to use function with pave between 2 crvs using iso lines to do this , but it's still hard to fit my require that I have to pave them manually.

do you have alternative solution for this as well?
thank you

Hi xlxdesign,

you need the latest version of gh (0.9.0076). The latest version has changed the Clean Tree component.
If persist, ssend me an image of error notification to


Comment by xlxdesign on May 5, 2016 at 9:04pm

About the Component Variable Offset,everytime I use it,a pop-up window comes out saying" clean tree is unrecognized".And the result is the component can't works.

Hope for your reply, Thanks a lot!

Hi Daniel
Thank you ever so much for your speedy reply! Very helpful :-)

Please add a discussion for consultations.

Hi Sandra,

as you can read on Size_param description or in the component description, the current release uses European Gauge (in all rings components). This is Radius = (size+40)/(2*Pi), where "size" is the value to give, it's usually used in countries like Spain, Italy, Netherlands, Switzerland... The next release will have 6 ways (5 regional system + diameter) to give it the size in different regional systems with just two clicks, in fact, the rings of the next release are already developed, but will have to wait...

Knowing that:

ISO (International Organization for Standardization). mm of internal circunference. Austria, France, Germany, Belgium, Scandinavia...

radii = Size / (2 * Math.PI) 

European Size. Spain, Italy, Netherlands, Switzerland...
radii = (Size + 40) / (2 * Math.PI) 

British Size. United Kingdom, Ireland, Australia, New Zealand, South Africa...
radii = ((Size * 0.4) + 11.5) / 2

American Size. United States, Canada, Mexico...
radii = ((Size * 0.83) + 11.54) / 2 

Japanese Size. Japan, China, India, South America...
radii = ((Size / 3) + 12.67) / 2

Diameter Size. Many goldsmiths anywhere.

radii = Size / 2


and since this release are UserObject componentes, you can remplace if you want the Size component with one new. For example, right clicking size_param, going to Expresion and setting x*pi-40, the size input will be the diameter of the resulting circle, if you give it a value of 14, the circle will have a radius of 7. Then save the userobject (File>Create User Object) and remove the other.

Or create a new one, since this component is just a rotated circle and a cylinder.

Hope this helps.

I have just started playing with the plug-in. Seem to have difficulties with the 'size'-function. What is the actual reference point for the ring-size? It does nit seem to match neither mm measurements nor American ring-sizes...please help

Thanks a lot

I just started playing with Peacock. I do production jewellery, mostly 925 silver and I use a lot of Swarovski crystals in enamel. I have tried to use your pave and twice it crashed. What I am wanting is to fill a predetermined area with crystals of specific sizes. Also looking at Kangaroo for circle packing. 

Best way to use pave. I have only played with your sample file. Thanks

Thanks Daniel for sharing

Comment by Daniel Martinez on February 23, 2015 at 11:07pm

but of course ::facepalm:: Thank you so much Daniel!

Comment by Daniel González Abalde on February 23, 2015 at 4:58am

Hi @Daniel Martinez.

Sorry for the password protected. You can redo the gem with Gems component, which has parameter to flip the stones as you wish.
