Why Do Diamonds Sparkle So Brightly Under The Light?

One of the main reasons people are so captivated by diamonds’ beauty is their bright sparkle. Whether it is a love band or a wedding ring, the sparkle of a ring is what makes a diamond ring so beautiful. 

Because of this breathtaking twinkle, sparkle has now become an essential requirement for ring shopping. But have you ever wondered why diamonds sparkle the way they do? And how do you find the right gem for maximum sparkle? 

To answer all these questions, you will need some knowledge about this precious gemstone. And in this article, you will read through the science behind the sparkle and how you can find the most glistening gem for your partner. 

So without further ado, let’s get started!

 

What Is The Science Behind A Sparkling Diamond? 

The reason why diamonds sparkle bright is because of the diamond’s cut as well the interaction of light.

When light rays first enter the diamond, they move straight through it and bounce off its interior surfaces. These are called facets, and they differ between diamonds based on their cuts. 

Once the light is reflected off the facet, there are two possibilities:

  • It leaves the diamond giving it a pure “white light” or,
  • It splits into several spectral colors, including red, yellow, orange, blue, green, and violet. This is called “fire.”

In addition to this, diamonds also give off “scintillation,” an effect that occurs as you move the diamond. When this happens, you will notice bright flashes of white as well as rainbow-colored sparkles that move along with diamonds. 

In simple terms, there is a contrast between light and darkness, which causes a sparkle.

However, other factors like the final diamond cutting and polishing also play an essential element in the shininess of a diamond.

 

How Do You Choose The Best Diamond That Glistens?

As mentioned earlier, a diamond sparkle is one of the essential features to consider while shopping. 

Listed below are three tips to help you zero in on the best diamond cut polish with the best sparkle!

 

Look At The Diamond With Different Lights And Angles

As mentioned earlier, light is the science behind a diamond’s sparkle. And what better to test out a diamond’s sparkle than by viewing under lights?

The best way to do this is with the spotlighting technique that will help you view every element up close. However, if there is too much light bouncing off the diamond, there will also be a lot of glare. This can make even poor-quality diamonds look as impressive as high-quality diamonds.

So make sure to check the diamond in a well-monitored environment with perfect lighting. Make sure to also observe the diamond under mixed lights as well as natural lights.

 

Notice The Cutting Style

The cut of the diamond also plays a vital role in the reflectivity of a diamond. Moreover, each diamond has different facets and reflective surfaces. The more the facets, the more chances of the light bouncing off to scatter the light. 

So if you are looking for a diamond stone with sparkle as your primary preference, you can opt for a round gem as it has almost 58 different facets within. On the other hand, single-cut diamonds only have 18 facets. 

But don’t worry! If you still wish to get another shape, you can still opt for the following forms:

  • Princess cut
  • Radiant cut
  • Oval cut
  • Pear cut
  • Heart cut
  • Marquise cut

 

Look At The Cut Quality

If you are still unsure about how to check the brilliance of a diamond, you can use the GIA Diamond Grading Report to help you out. With this, you can easily spot the shiniest diamond on the market.  

GIA aims to analyze diamonds and give them a rating based on their brilliance, and they are:

  • Excellent
  • Very Good
  • Good
  • Fair 
  • Poor

If you want a diamond with amazing shine, you can opt for one with an “Excellent” GIA grade. This also indicates that the diamonds have been made with skilled craftsmanship and careful attention to polishing the diamonds

 

Wrapping Up

Seeing a sparkly diamond in a store might look appealing. However, there is a long, detailed process behind it to ensure every diamond sparkles the right way.

This is why a diamond polisher spends hours polishing the rough edges to help with the scintillation effects. In fact, you can see the stunning results of this every time you move the diamond!

Needless to say, the intense array of bright colors and lights is what makes a diamond such a truly prized possession.
