Everything You Need to Know About Round Cut Diamonds

Round cut diamonds are the classic diamond shape.

Round cut diamonds are the classic diamond shape. Even the diamond emoji is a round cut - and statistically, round brilliant cuts make up 70% of diamond engagement rings sold today. 

You might assume a popular diamond would be a rather dull choice? Au contraire! Brilliant cut diamonds are the best-selling diamonds because they are simply the best at what they do.

And what they do best is sparkle.

What is a Round Cut Diamond?

Round brilliant-cut diamonds have 58 facets including the culet – the flat face on the bottom – or 57 without it. A well-cut round diamond can reflect nearly 100% of light, making it the most brilliant cut available. 

The round shape requires more raw diamond to be left behind in the cutting process. This, plus high demand, make brilliant-cut diamonds a bit more expensive. 

However, because round diamonds refract light so well, they have a unique ability to mask yellowish tones and slight inclusions visible in other stones. 

A well-cut diamond will look better and shine brighter than a less desirable cut on a diamond of the same color, allowing you to save money without sacrificing beauty.

Old European cut diamonds are the vintage equivalent to the modern round cut. Popular before the advent of contemporary diamond technology, these stones were hand-cut for their color and measured by eye. 

These antique stones can be identified by their higher crown, larger culet, and smaller table. The deeper cut played on light and dark flashes known and was known for its "inner fire."

They have since been replaced by round brilliant cut diamonds, which possess superior brilliance, fire, and scintillation due to their precise cut.

Round cut diamonds bring one thing to the table above all else, that sparkle! Diamond cutters have been perfecting tools and techniques to bring out that unique sparkle and shine for decades.

How do you measure the perfect cut? It all comes down to three main ingredients.

Diamond Brilliance

Brilliance is what we call the sparkle from a diamond.

  • • Well-cut round diamonds are designed to reflect as much white light as possible
  • • Measured by the white light reflected off the table
  • • The round cut provides more brilliance than any other shape

Diamond Fire

Those little glints of rainbow light? That's fire.

  • • A well-cut stone shows off a ton of color in its sparkle
  • • Fire is measured by the amount of colored light reflected

Diamond Scintillation

Scintillation puts the bling into brilliance

  • • The term refers to the flashes of light bounced off each facet when the stone is in motion
  • • Flash scintillation: the flashes of white light reflected off a diamond
  • • Fire scintillation: flashes of color
  • • Round cut diamonds are ideal for their scintillation as they let in light from every angle

Ok, fancy terminology aside, what does this mean for you and the gem of your dreams? Basically, an eye-clean diamond (one that looks good to the naked eye) and has a high cut grade is a good choice. 

We pre-select all of our stones for brilliance, fire, and scintillation. So when it comes to sparkle, we've got you covered.  

Conclusion
