Why so Shinny quick guide to why Diamonds Sparkle

  • 2 min read
Diamonds have always been the most popular choice for engagement rings, and for good reason. They are not only the hardest natural substance on Earth, but they also have a unique ability to sparkle and catch the eye like no other gemstone. But what is it about diamonds that makes them sparkle so brilliantly? In this blog post, we'll dive into the science behind a diamond's sparkle and explain why it makes them the perfect choice for your engagement ring.


Firstly, let's start with the basics. A diamond is made up of carbon atoms that have been arranged in a particular crystal structure. This crystal structure is what gives a diamond its unique optical properties. When light enters a diamond, it slows down and bends, which causes the light to bend and refract. This bending and refracting of light is what gives a diamond its famous sparkle.

But why do diamonds sparkle more than any other gemstone? The answer lies in the way that light interacts with a diamond's crystal structure. A diamond has what is known as a high refractive index, which means that it bends light more than any other gemstone. This bending of light creates what is known as "dispersion", which is the rainbow of colors that you see when you look at a diamond.

In addition to its high refractive index, a diamond also has what is known as "total internal reflection". This means that when light enters a diamond, it can bounce around inside the diamond and reflect off its surfaces. This bouncing and reflecting of light is what creates the diamond's famous "fire", which is the flashes of color that you see when a diamond is moved.

So, in summary, a diamond's sparkle is due to its unique crystal structure, which causes light to bend and refract more than any other gemstone. This bending and refracting of light creates dispersion and fire, which is what makes diamonds so visually stunning.
