Do lab-grown diamonds require different CAD settings than mined diamonds?

No — the physical dimensions and setting requirements are identical, so no adjustment to the modeling process is needed.

Can a design be rendered with both lab-grown and mined diamond options for comparison?

Yes, since the material properties are visually identical, the same base render can represent either stone type without modification.

Is customer demand shifting design requests toward larger stones?

Many designers report exactly this trend, as lower per-carat costs make larger center stones more attainable for the same budget.

Lab Grown Diamonds and 3D Jewelry Design: What’s Changing

by Arvion Designs

on September 30, 2026

Lab-grown diamonds and 3D jewelry design intersect mainly at the setting and rendering stage — the stones themselves are optically identical to mined diamonds, so 3D modeling and material rendering treat them the same way, while their lower cost is shifting what size and quality stones brands design around.

Why Lab-Grown Diamonds Don't Change the 3D Modeling Process

Physically and optically, lab-grown diamonds share the same properties as mined diamonds — hardness, refractive index, and sparkle. This means CAD modeling for settings (prong height, stone seating) and rendering material properties require no special adjustment compared to designing for mined stones.

Where the Real Impact Shows Up

Larger center stones becoming standard requests — since lab-grown diamonds cost significantly less per carat, clients increasingly request larger stones in custom designs than would have been typical with mined diamonds at the same budget.
More elaborate multi-stone designs — lower stone costs make pavé and halo-heavy designs more accessible, which slightly increases the modeling complexity of typical custom requests.

Marketing Implications for Brands

Brands offering lab-grown options benefit from 3D rendering’s ability to easily produce side-by-side comparison visuals or size-comparison renders, helping educate buyers on the value proposition without needing physical stone samples of every size.
