How Does a Diamond’s Cut Affect Its Sparkle and Light Performance?
PAGE
By PAGE Editor
Most people looking to buy diamonds pay attention to size or clarity. However, the most important feature of a diamond is its cut. Cut determines how a diamond reflects light, and consequently, how much it sparkles. A well-cut diamond sparkles brightly and looks alive; however, a poorly cut diamond, regardless of clarity or size, will look lifeless.
If you are looking for a diamond that truly shines, then shopping with Rare Carat is a smart choice. With their expert tools and comprehensive details, Rare Carat’s selection, including 1.75 carat marquise cut diamonds and bold 12 carat round cut diamond options, all expertly crafted to ensure optimal sparkle.
Why Diamond Cut Matters
The cut of a diamond does not refer to its shape (such as oval or round), but rather how well it is crafted. A diamond’s ability to shine is reduced when its cut is deeper or shallower than ideal as light would escape. When all angles of the diamond are properly balanced, light entering from the top will reflect back out, providing that sparkling effect that everyone loves. Striking brilliance, rainbow-like fire, and beautiful flashes of light (or scintillation) are the effects of a well-cut diamond.

Rare Carat also features the stunning 12 carat round cut diamonds that are equally beautiful and expertly cut for brilliance. If you want a round shape, these diamonds are the best choice since their appeal and shine are unmatched. The round brilliant cut is even said to be the best for sparkle because it has 58 facets, provides unmatched shine.
What Makes a Diamond Sparkle?
Three main effects determine a diamond’s sparkle:
Brilliance – The bright white light reflected from the surface and inside the stone.
Fire – The scattering of white light into flashes of color.
Scintillation – The sparkle that moves across the surface when the diamond is in motion.
When cut correctly, all three are balanced perfectly. The result? A diamond that captures attention from every angle.
