The uploaded images are 3D renderings of five different wedding ring models, all of which are ready-to-make digital files (CAD/STL) for online sale.

Below, I provide technical and design descriptions for each model for use in online sales of the ready-to-make file (excluding gold and stone costs). These descriptions will help buyers (jewelers) to understand the details of the model well:

Technical specifications and design of ready-to-make ring files

All models are set rings without diamonds/stones (Plain Band or Patterned) and are designed to be made with gold metal (yellow, white or mixed).

1. Model cr0047: Modern V-Cut Set Ring

• Design: Wide, with a shiny and polished outer surface.
• Features: Deep V-Cuts create a triangular pattern along the circumference of the ring. These cuts give the ring a sharp, geometric, and modern look.
• Structure: A single ring with uniform thickness and no need to assemble multiple metal pieces.
• Suggested color scheme (in the rendering): Single color, yellow gold.
• File usage: Suitable for direct casting and final finishing.

2. Model cr0048: Puzzles Set Ring

• Design: Two-tone with a geometric cut-out pattern resembling a plus sign or criss-crosses along the body.
• Features: Two-layer/two-tone design; the outer layer (white gold in the rendering) is a lattice, and the inner layer (yellow gold with a matte texture in the rendering) is visible from behind these grids.
• Structure: Requires assembly of two metal pieces (or use of specialized coloring/plating techniques). The details of the inner surface (Mesh Pattern) create strong visual interest.
• Suggested color scheme (in rendering): A combination of shiny white gold and matte/textured yellow gold.
• File usage: Ideal for jewelers looking for more complex models with a combination of color and texture.

3. Model cr0004: Twist/Curved Edge Ring

• Design: Wide and with irregular and curved edges that create a twisted and dynamic appearance.
• Features: The cross-sectional surface of the ring is twisted and angled at different points (like a spinning bar). These angles create different light reflections and distinguish the appearance of the ring from a simple model.
• Structure: Single ring with a shiny and polished outer surface.
• Suggested color scheme (in rendering): Single color, high-gloss yellow gold.
• File usage: A model suitable for those interested in modern and minimal designs with subtle structural details.

4. Model cr0046: Quilted/Diamond Pattern Ring

• Design: Slim/medium, with a raised diamond-shaped pattern (similar to quilting or capitonné stitching) on ​​the outer surface.
• Features: A regular and raised pattern of a network of diagonal lines that intersect and create diamond-shaped sections. The shiny surface of the diamonds creates strong light reflection.
• Structure: Single ring with a patterned outer surface.
• Suggested color scheme (in rendering): Single color, shiny yellow gold.
• File Usage: Ideal for those looking for a patterned ring with interesting depth and texture.

5. Model cr0028: Celtic Knot Set Ring

• Design: Wide, with a Celtic Knot or Slime pattern in the middle band.
• Features: Tri-color/Tri-layer design: two wide side bands (shiny yellow gold), and a narrow middle band with a Celtic lattice pattern (white gold in the render) that may be accompanied by enamel or small decorative gems (although the current model is without gems).
• Structure: Requires precise assembly of multiple metal pieces to display color designs (Inlay) or the possibility of printing and casting as a single piece and then applying plating techniques for color.
• Suggested Color Scheme (in Render): A combination of yellow and white gold to highlight the center design.
• File Usage: A model with classic and traditional details for jewelers who are skilled in creating intricate designs.
