What Makes A Diamond Sparkle?

A diamond is a beautiful and timeless symbol of love. Whether you are giving one as an engagement ring or purchasing it for yourself, the first thing you'll notice is how incredibly sparkly and gorgeous they are. But what makes a diamond "sparkle?" Let's take a look.

The cut, color, and clarity of a diamond are the main determinants of its quality. While these qualities are essential for any stone (or gem), how they interact with light to create sparkle will make or break your decision to purchase one.


A diamond cut creates the appearance of sparkle by allowing light to play across its surface in a specific way. This allows for maximum reflection and refraction, which results in that mesmerizing luster we all love. When picking your stone, make sure you ask about how the prongs are set because this will determine the amount of light the diamond reflects.


The color of a diamond is measured on the Mohs scale. This measures how 'white' (or clear) it is. The whiter or clearer your stone, the more sparkle you will get from it because there aren't any impurities to distort its light. A few grades down, and you will notice that beautiful sparkle fade away.


A stone's clarity refers to any imperfection within the body and has nothing to do with the sparkle factor. The more pure and clear the stone is, the less likely it will be to have any inclusions or flaws make their way into your diamond.

In other words, clarity is the most critical factor when determining sparkle and beauty, because it determines how clear or cloudy your diamond will be. A diamond with a clarity scale grading from "completely flawless" to SI (slightly included) ensures maximum visual clarity.

Carat weight

Carat weight refers to the weight of a diamond. One carat is equal to 200 milligrams or 0.200 grams (0.007055 oz). Large diamonds typically weigh more than smaller ones. Most people associate larger diamonds with higher quality and better sparkles because they are rarer, more challenging to find, and more expensive.
