Jewelry Generator

Jewelry Generator builds photoreal jewelry inside Blender: engagement rings, wedding bands, earrings, necklaces, pendants, bracelets, brooches and cufflinks, every one set with real-cut gemstones in real metals. Pick one of 179 designs modeled on real pieces, then change anything: the stone, the cut, the carat, the setting, the metal, the finish or the ring size. The piece rebuilds live as you click and drag.

Gems are cut, not faked. Forty cuts are built facet by facet from real proportion tables: round brilliant, oval, cushion, princess, emerald, Asscher, radiant, marquise, pear, heart, trillion, baguettes, old European and old mine, rose cuts, step cuts, checkerboards, briolettes, cabochons and pearls. Carat sizes come out at real millimetres: a one carat round brilliant measures 6.5 mm.

Settings follow how jewellers really make them. Prongs hug each stone's outline and grip its corners and points, with claw, round, tab, V and split tips. Choose baskets, bezels, tension, halos, pavé, channel and bar settings. Stone counts are always whole numbers.

Materials look right in both EEVEE and Cycles: 41 gemstones with fire and color, pearls with lustre and overtone, opal, moonstone and star sapphire, and 20 measured metals with polished, satin, brushed, hammered and antique finishes. A one-click photo studio adds jewellery lighting, backdrops and a camera.

Installation

In Blender open Edit, Preferences, Get Extensions, then use Install from Disk and pick the jewelry_generator zip.

Usage

• Open the Jewelry tab in the 3D viewport sidebar (N). With nothing selected, pick a category and a design picture, then press Add. You can also use Shift+A, Mesh, Jewelry.
• The top of the panel shows the piece, its size and carat total, quick metal swatches, the gem and cut, the carat and (for rings) the ring size. Surprise makes a random new piece.
• The tabs hold every setting: Design (the piece's own shape), Stone (cut, gem, size and proportions), Setting (prongs, baskets, bezels, halos), Accents (pavé and side stones), Finish (metal, finish, wear, pearls, enamel) and Studio.
• Studio adds a one-click photo set with lights, backdrop and camera, in EEVEE or Cycles.
• Convert to Mesh turns the piece into plain meshes for export; Delete removes it with all its parts.

Use Rendered view to see the gems sparkle. Rainbow fire shows in both engines; Cycles gives the most accurate refraction.

Which Blender versions are supported?

Blender 4.2 and newer. It is tested on Blender 4.2, 4.5 and 5.2 LTS.

Does it work in EEVEE?

Yes. Every metal and gem has an EEVEE version, and the studio uses EEVEE by default. Cycles gives the most accurate refraction and caustics.

Are the sizes real?

Yes. Models are in real millimetres, ring sizes give the exact inner diameter, and stones are sized by carat with real gem densities.
