Colorless diamonds, specifically those graded D (no color), shine the most because they allow maximum white light to pass through for superior brilliance, while warmer-toned diamonds (like K-M) have yellow tints that reduce light reflection and sparkle; however, cut quality is paramount, with the round brilliant cut designed for maximum light return, creating the most sparkle, often outshining color grades in lower-quality cuts.
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. And as a result, will produce less sparkle. A D-color diamond is the highest quality, and will offer the greatest sparkle.
Round Brilliant Cut – The Sparkle Champion
The Round Brilliant Cut is known for being the most sparkly diamond cut. This classic cut features 58 facets, strategically designed to maximize the reflection and refraction of light.
A real diamond appears gray and white inside (brilliance) when held to the light and can reflect rainbow colors (fire) onto other surfaces. A fake diamond will display rainbow colors within the stone when held up to light.
Of all the diamond cuts, the baguette has the least amount of sparkle. Though its long rectangular shape and step cut facets give it an unusual and alluring appearance, it has far fewer facets than other cuts (an average of 14).

Because inclusions are more visible in diamonds with larger, open facets, you should pick VS1 over VS2 when choosing diamonds in shapes other than round (particularly in step-cut diamonds such as emerald-cut or Asscher cut).
Diamonds, like any surface, can accumulate dirt, oils, and grime from everyday activities, including hand lotion, soap, cooking materials, and perspiration. These substances can form a film on the diamond's surface, which can diminish its sparkle and make it look dull.
While not all diamonds can glow in the dark, those that do possess a captivating and mysterious beauty. The science behind diamond fluorescence reveals the intricate interplay between the diamond's atomic structure and impurities, resulting in a mesmerizing glow when exposed to UV light.

Meghan's original engagement ring was estimated to be 4.5 carats. The ring consists of a three-carat cushion-cut centre stone, with two round-cut side stones, with each stone being approximately 0.75 carats each.

For example, because round diamonds are the most popular and desired diamond shape, a round diamond will fetch a higher price on the secondhand market than, say, a marquise diamond with the exact same attributes. The more popular the diamond shape, the more those diamonds will fetch.
Colorless Diamond Grades
D and E-colored diamonds have virtually no color, and F diamonds have a nearly undetectable amount of color that shows only in the face-down position (when the diamond is viewed from the bottom). These icy-white diamonds are the rarest and the highest quality in color.

It depends on what you prioritize. If you want maximum certainty of no visible inclusions and are willing to pay more—VVS1 or VVS2 might feel safer. If you want value and are fine with a small chance of visible inclusions under magnification, VS1 or VS2 often gives excellent appearance without the extra cost.
