The Magic of Diamond Rendering

With consumers moving increasingly online to purchase their luxury goods, jewelry companies must launch digital stores to maintain sales. But there are several challenges to consider: can a digital experience duplicate the personal touch of a real one? Is it possible to showcase jewelry accurately in online stores? Can 3D modeling and rendering create a true-to-life image of such elegant gems as diamonds? We at Postindustria know it can. Read further to discover insight on diamond rendering’s advanced technologies.

    What is diamond rendering?

    Rendering is a process of generating photorealistic images from the 3D or 2D models of an object. Before adopting this technique, you should create a 3D visualization of your products while taking their materials and geometry into account. For companies that use 3D printing, however, it’s possible to render realistic images from the 3D jewelry models used in production. 

    3D modeling and rendering capture the product’s tiniest details that are not visible in ordinary photos. Rendering is a particularly good choice for diamonds as the technology simulates light refraction and other optical effects. It’s a perfect solution for creating accurate images of the jewel. Now, let’s look at how we can achieve it. 

    Rasterization vs ray tracing

    We’ll compare two different rendering approaches to find out which one is more suitable for creating virtual diamonds. 


    Rasterization is a rendering technique that comes from the 1970s. It was first applied in television’s early days and has been popular since. Rasterization allows creating raster images from the vector ones. In other words, you can take the object’s geometry and convert it into a picture made of pixels. And the approach’s main advantage is it renders 3D images at lightning speed. That’s why most AR mobile applications use the rasterization technique. 

    Here’s how rasterization works. Polygons, the shapes forming the 3D model, are broken down into triangles. The algorithm then breaks down these triangles into pixels and creates a raster image. The problem is, rasterization can’t capture the object’s color and light, so you must additionally assign a specific color for each pixel through various shading techniques. But you still won’t reach 100% object shading accuracy in the end. 

    Ray tracing

    Ray tracing is another rendering technique you can use. Its algorithm traces the light’s paths as pixels while simulating how it interacts with objects. This process allows ray tracing to capture optical effects accurately, such as scattering, reflections, and refractions. Ray tracing’s main advantage is creating realistic images. Although, compared to rasterization, this approach takes a bit more time to render a 3D model.

      And the winner is…

      Ray tracing! Yes, rasterization may be good for AR mobile apps and games when you need to display an image quickly and in real-time. But to make a virtual diamond look real, ray tracing is the only way. It helps you capture the crystal structure of each diamond precisely, as well as its optical properties. 

      The applications of diamond rendering 

      Why do jewelry companies consider rendering 3D images of diamonds? Because accurately rendered images have many applications in the digital world.

      AR apps

      63% of customers say augmented reality may buff their shopping experience. And jewelry companies know that. Nowadays, to ensure interactive and engaging online shopping, they build AR applications. These style apps allow them to showcase their jewelry and provide a try-on option for shoppers with possible customization included. 

      AR jewelry app development involves rendering product images while diamond ray tracing creates realistic images of the jewels. Together, with tracking users’ movements and lighting and surroundings’ estimation, they produce a stunning “try-on” feature.

      Digital catalogs

      When creating a digital jewelry catalog, the more realistic the image looks, the better you’ll sell. You can showcase your products online in a way that allows visitors to interact. For instance, they can rotate the jewel to view it from any angle. A digital 3D catalog can be a part of an AR jewelry app or be a separate website solution.

      Social media platforms

      Apart from the web and mobile apps, you can use rendered diamond images for social media content. Be it Facebook, Instagram, Twitter, or TikTok – visual representation matters. In fact, Microsoft’s research shows how modern humans have a short attention span –  only 9 seconds. This means visual content is the most effective way of grabbing someone’s attention. No doubt, a realistic, eye-catching image of a jewel will do the trick.

      Wrapping up

      With the global pandemic unfolding, most retail stores are moving to digital. But traditional e-commerce is not enough for jewelry companies. Online shopping can’t substitute offline purchases. The reason is, it struggles to offer the same product experience. Luckily, with 3D jewelry modeling and rendering, buying jewels online is a bit more reliable and adds a personal touch. By adopting AR technology, online shopping becomes more interactive and engaging. 

      As for diamonds, ray tracing is the best rendering technique. It creates a realistic image of the jewel by taking its optical properties into account. And if you develop an AR app with a “try-on” feature, your virtual jewelry will look the same on the user as it does in real life. 

      We, at Postindustria, help our partners create custom AR solutions for jewelry.
