The Secret Behind Lab-Grown Diamonds' Sparkle

Written by Nicole Harper

The Secret Behind Lab-Grown Diamonds' Sparkle

It is hard to criticize the gemological beauty of diamonds, especially when they catch the light well. That brightness and iridescence that produces flashes of light in the stones every time your hand moves slightly? That's what we call diamond sparkle, and it is what makes diamonds so memorable.

Now, imagine if we could say you would have that same remarkable sparkle in a modern and ethical way that looks just as beautiful. 

Enter lab-grown diamonds! At Friendly Diamonds, we are proud to offer certified and quality-controlled loose lab diamonds that not only look the part but also feel the part, giving you that brilliant sparkle with none of the guilt. Are you ready to enjoy the sparkle that shines oh so brightly?

The Science Behind Diamond Sparkle

A diamond's sparkle isn't some sort of random event but rather a calculated phenomenon of how light will reflect off the surface. The shine of a diamond is defined by the 4 C's (Cut, Clarity, Color, Carat). While all 4 C’s matter, the biggest star of the show is the cut of the diamond.

Think of a diamond's cut like a tiny mirror maze. An ideal cut will boast facets that are perfectly angled so the facets act as a director and create maximum return of light as it enters the diamond, reflects within it, and comes back up to your eye. With that being said, there are three aspects of a diamond that can be maximized:

Brilliance: The bright white light reflection gives off a bright, fiery sparkle.

Fire: The dispersion of light into all the colors of the rainbow, as a tiny prism might do.

Scintillation: The flashes of light and dark spots you see as the light is in motion or you are in motion; pure motion!

What a great reality: Lab-grown diamonds are chemically, physically, and optically the same as mined diamonds. If they are the same at the composition level, which they are, they will also have the same optical properties. So it comes down to cut, and according to the gemologist's guide, in terms of the diamond sparkle you crave, there is no difference! 

Friendly Diamonds is very proud to offer lab-grown diamonds that have been cut to perfection with tools and by artisans who are masters of their craft. Rest assured knowing that each one of our diamonds has maximum brilliance and scintillating diamond sparkle. We are talking diamonds that will light up a room.

Why Lab-Grown Diamonds Sparkle Just as Bright

Let’s get one thing straight: Lab diamonds are not fake. They’re not synthetic. They’re not ‘almost’ real. They are real diamonds; they’re just grown in a lab rather than pulled from the Earth.

Thanks to high-tech equipment, we can simulate diamonds created by nature by applying heat, pressure, and carbon, three things Mother Nature employs to make diamonds. The end result is a diamond that is chemically, physically, and optically the same mineral crystal as mined diamonds.

All of our diamonds are IGI and GIA certified; that means that each and every diamond is being measured by the same strict characteristics: cut, clarity, color, and yes, miraculous sparkle.

And of course, our diamonds are only a fraction of the price of mined diamonds. Get that bigger, even sparklier diamond without sacrificing quality, ethics, or price.
