The way that diamonds reflect light is unique: the inside of a real diamond should sparkle gray and white while the outside should reflect a rainbow of colors onto other surfaces. A fake diamond, on the other hand, will have rainbow colors that you can see inside the diamond as well.
Keep it clean.
The truth is, dirty diamonds don't sparkle! Even a well-cut stone can't shine if it's obscured by dirt and debris. Keeping your diamond ring clean will ensure that it's always dazzling.
Round Cut Diamonds Sparkle The Most
The standard round cut diamond comprises 57 facets (58 including one on the bezel). This cut heightens the diamond's sparkle and shine. Because round diamonds have the largest number of facets, they create the most sparkle.
A well-cut diamond will reflect much more light than a poorly cut one, resulting in a more substantial, more visible sparkle. It is recommended to limit your diamonds to a high-quality cut grade. Also, the more facets a diamond has, the more reflective surfaces there are to spring back and scatter light.
A real diamond provides an exceptional sparkle since it reflects white light extremely well. In addition, diamonds can also reflect fire or colored light in a beautiful display. Compared to a stone like Cubic Zirconia, you'll be able to see a huge difference in the white and colored light sparkle.
For each individual diamond, there are specific proportions that will make the diamond sparkle at its best, and it is far better to have an Ideal-cut diamond that is 0.90 carats than a poorly cut diamond that is 1.00 or 1.10 carats. A good cut will result in a better sparkle.
But sometimes we see diamonds that look cloudy, hazy or dull. Problems with the diamond's transparency may be the culprit and can result from several different causes. A diamond that is not properly cut will leak light and appear less brilliant and fiery than it should.

Color also has a big impact on the sparkle produced by a diamond. Because diamonds reflect white light, colorless diamonds produce the best sparkle and fire. In fact, the more color a diamond has, the less likely it is to reflect white light.
It's Not All About Size. It's a common misconception that the larger a diamond is, the more it will sparkle. Although the bigger stone might have space for more facets, two diamonds cut the same will sparkle the same, regardless of carat size. As you shop around, consider cut over the diamond's weight and measurements.
Which diamond cut has the least sparkle? Baguette is the worst diamond shape in terms of brilliance. This shape makes a diamond sparkle less, even if it has an ideal cut.
Light is everything. It's the source of a diamond's beauty. Without light, there are no reflections. No sparkle.
Even a moderate amount of dirt, grime or otherwise unpleasant sediment and “film” can have a severe effect on the sheen and shine of that precious stone in your precious ring. And over time, things like hand lotions, powders, soap, hairspray and more can really build up on and dull your diamond's glitter and glimmer.
The highest color grade for a diamond is “D”. “D” color diamonds are very rare and not commonly found in traditional jewelry. Most diamonds used in jewelry have a slight presence of color. It is possible for diamonds to have a very high concentration of desirable color.
Round brilliant cut diamonds are easily the most expensive diamond shape. In part, that's because round is the most popular diamond shape. More than half of all the diamonds sold today are round diamonds. This incredible popularity means that diamond miners and retailers can charge more for such an in-demand shape.
Moissanite has unparalleled sparkle! It has a higher refractive index than diamond, resulting in greater brilliance than diamond. Moissanite also has greater dispersion (fire) than a diamond, so you will notice more rainbow flashes of light.
An ideal cut diamond shows only a few intensely bright flashes in direct sunlight. A diamond that actually looks good in sunlight splits those few flashes up into ten or twenty smaller sparkles.
Genuine diamonds do not sparkle in rainbow colors inside of the stone. Instead, the inside of real diamonds sparkles in tones white and gray. The play on light in the diamond is brilliance.
In cut stones, cubic zirconia tends to have dull, rounded edges, while diamonds' facets stay sharp. Diamonds rarely show polish marks, but if they do, they will be in different directions on different facets. On the other hand, cubic zirconia will show polishing marks in the same direction on adjoining facets.
While a diamond may look cloudy and milky because of inclusions, strong fluorescence, or even a poor cut grade, those aren't the only reasons it may have appeared to lose its stunning shine.
Diamonds look brighter if a high percentage of the light coming directly from the source is refracted and returned to the eye. When a diamond looks brighter it also tends to look bigger. In addition, when a diamond looks brighter it also looks whiter which is yet another reason ideal cut diamonds are worth a premium.
Fair/Poor Grade Diamond Examples
Fair and Poor cut diamonds usually have steep crowns and steep pavilion angles which gives them a really dark looking appearance. This makes them look extremely small for their carat weight. Because of their abysmal proportions, their brilliance and sparkle are horribly affected.
