This is a collection of 3D models of various gemstone cuts, i.e., gemstone shapes.

In the collection you can find the following diamond shapes Brilliant, oval, Baguette,  Heart, Coffin, Radiant, Princess, Cushion, Emerald, Octagonal, Hexagonal, Trillion, Triangle, Pear, Marquise (Navette) and Flanders gemstone cut.

The 3D models were precisely constructed and their names inscribed next to each one. You only need to import them into the 3D software you are using and, from then onwards, it will all depend on your knowledge and creativity. We decided to offer you these 3D models of gemstone cuts because, at first glance, they appeared to be very simple 3D shapes. However, you need to know that their modeling done with NURBS 3D CAD software is tedious and time- consuming. Once they are created, you can insert them into various 3D models as design elements. Our intention was to give you the time you would have spent modeling them yourself, since we generated them very quickly in some special jewelry modeling software.

Gemstone cutting is the process of cutting precious and semi-precious stones until they obtain a certain shape that is suitable for making jewelry and their final mass, beauty and shine are maximized. It implies various technological processes such as sawing, grinding, sanding, and polishing, with the aim of creating many geometrically arranged, flat surfaces called ‘facets’.  Facets improve a gemstone's appearance by optimizing its optical performance and allowing it to reflect light. There are a large number of gem cutting styles and we have made available to you 3D models of the most famous and common ones – the brilliant/oval/baguette cut (see picture).
All the 3D models of gem cuts in this collection were generated as polygonal mesh 3D models and then transformed into NURBS, i.e., solid 3D models. Both the mesh and NURBS versions of 3D models are available to you.
