Does gemstone cut affect the price of 3D design services?

Not significantly on its own — complexity is driven more by the overall setting style than by stone shape alone, though unusual or highly custom cuts may add minor modeling time.

Can I combine multiple cut shapes in one piece?

Yes, this is common in designs with a center stone plus accent stones of a different shape.

Which cut is best for maximizing perceived size?

Elongated cuts like oval and marquise tend to appear larger than round cuts of the same carat weight due to their shape.

Diamond and Gemstone Cuts Guide for Custom Jewelry

Choosing a diamond or gemstone cut affects both the visual character of a piece and how it’s modeled in 3D — round brilliant cuts maximize sparkle, while fancy cuts like emerald or marquise emphasize clarity and elongation. Here’s a quick guide to the most common options.

Round Brilliant

The most popular cut, engineered with 58 facets to maximize light reflection and sparkle. In CAD modeling, round stones are the most straightforward to seat in most setting styles.

Oval and Marquise

Elongated cuts that create the appearance of a larger stone and can visually lengthen the finger when set on a ring. These shapes require careful prong placement in 3D modeling to secure the pointed ends common to marquise cuts.

Emerald and Asscher

Step-cut styles with flat, layered facets that emphasize clarity over sparkle — any inclusions are more visible in these cuts, which is a consideration when selecting the actual stone, separate from the 3D design itself.

Princess and Cushion

Square or rectangular cuts offering a modern look (princess) or a softened, vintage-inspired square (cushion) — both require precise corner and edge modeling in CAD to ensure secure prong or bezel settings.

How Cut Choice Affects the 3D Modeling Process

Each cut has different proportions and facet structures that must be accurately represented for the setting to fit properly and for rendering to display correct light behavior — an emerald cut, for instance, requires very different prong geometry than a round brilliant.
