Maximize the Brilliance of Your Valentine’s Jewelry with Optical Simulations

SPEOS simulations help you optimize a gemstone’s cut, carat, clarity and color.

We all want our valentine’s jewelry to sparkle like sunshine as soon as our someone special opens the box. But, how do we gift the glitteriest diamond?

A gemstones’ true potential is realized by its cut, carat, clarity and color (the four C’s). The better we understand the optical phenomena associated with the four C’s, the better we can maximize the gemstone’s radiance.

With the help of ANSYS SPEOS optics simulations, you can understand the phenomena that ensure your valentine’s jewelry will catch the eyes of Cupid, Aphrodite and the rest of Mount Olympus. 

Why Your Valentine’s Jewelry and Diamonds Shine so Bright

When it comes to optimizing the shine of diamonds and other precious gemstones, the whole process begins with the rough crystal. The cut applied to the rough crystal needs to maximize the yield (carat), clarity, color and light shining into the eyes of your valentine.

How light reflects inside a diamond

The cut is important because it dictates the angle the light enters and reflects through the diamond. In fact, the cut turns the diamond into a system of lens and reflectors.

The top of the diamond, its crown and table, allow light to enter. The light is then focused into the bottom of the diamond — its pavilion. The light then bounces around the inside of the diamond until it hits a facet at a critical angle and escapes.

If the light escapes at the top of the diamond, it sparkles. If the light leaks out of the bottom of the diamond, it appears dull. A dull diamond means that the cut can be further optimized to increase the diamond’s shine and value.

The cut also impacts the color of a diamond. As the light bounces around the rock, it will diffuse and disperse as if it were passing through a prism. The more the light bounces, the more color and fire the diamond will have.

How to Simulate the Shine and Color of a Diamond in SPEOS

A diamond of similar size and material will have a very different shine based on its cut.

If you want to maximize the gleaming light and color coming from a diamond — before you start cutting — then you need to simulate it in SPEOS.

SPEOS traces all light beams that travel from a source, through the gemstone and to your valentine’s eyes. It then calculates the shimmer and color of every virtual facet.

The software will take various conditions into account when simulating the rock’s glimmer, such as its:

  • Size.
  • Shape.
  • Facet arrangement.
  • Proportions.
  • Illumination.
  • Position.
  • Background.
  • Viewing conditions.

After creating the 3D model of the diamond in SPEOS, you can set the cut and color of the stone. Next, define the refractive index, dispersion and lighting environment.

How to Finalize the Cut of your Valentine’s Jewelry

One of the biggest benefits to SPEOS is that you can test how the setting and jewelry affects the fire of the gemstone.

Once the diamond’s simulation is set up in SPEOS, you can start optimizing it by playing with the cut.

You can even add a coating to the stone to see how it will affect the outcome.

Also, remember to change the angle of each facet, especially if you are changing the material of the gemstone.

Since each material has a different refractive index and critical angle — no other material will sparkle like a diamond. Therefore, different materials need different cuts.

Once you are done optimizing the cut, you can digitally insert it into a piece of jewelry. Being able to test how the jewelry’s setting can affect a gemstone’s fire is one of the biggest advantages of SPEOS.

You can even test the jewelry in a virtual reality thanks to the ANSYS VRXPERIENCE. This tool helps you assess how the jewelry will react in a virtual setting with a stereoscopic view. This stereoscopic view will make it possible to predict how the diamond will flicker.

It’s best to virtually test many shapes, facets, patterns, proportions and jewelry settings. With SPEOS you have a better idea of how the jewelry will turn out before you start cutting the gemstone. This is the best, and most affordable, way to optimize your valentine’s jewelry.
