The spell-binding beauty of gemstones has enticed gemologists as well as the masses since time immemorial. Often they wonder, why some gemstones sparkle so much and why others don’t. The answer lies in one single term - Brilliance.
In layman's language, Brilliance in a gemstone is the amount of light that a cut gemstone reflects to the spectator from the inside of the stone. Technically, it is the way taken by light to travel through the stone. However, the sheer irony is out of color, clarity, and cut factors, the cut of the gemstone is the most underrated one. Because of perfect cuts in gemstones, the light gets refracted inside a gemstone and exhibits brilliance.
The principal question that pops up here is what affects brilliance in a gemstone? What are those vital factors that regulate the amount of brilliance in a gemstone? To answer all these crucial questions, we have created this utterly informative and comprehensive guide on brilliance in gemstones that will help you to understand the basics of gemstone brilliance and judge the quality of any gemstone in a much better and lucid way.

Often, Gemstones are cut in different shapes and styles to amp up their beauty and brilliance. The way a lapidary cuts a gemstone affects its brilliance to a great extent. It determines how light is refracted within the stone.
Below, we have jotted down some common gemstone cuts and how they affect brilliance:

Round Brilliant Cut: This is the most common cut for diamonds and it is designed to maximize the amount of light that enters and reflects back out of the stone. The facets are arranged in such a way that allows for maximum light reflection, resulting in a high level of brilliance.
Princess Cut: This cut is similar to the round brilliant cut but with a square or rectangular shape. It also maximizes light reflection, but its corners can be vulnerable to chipping or damage.
Emerald Cut: This cut has fewer facets than the round brilliant or princess cuts, and instead of maximizing light reflection, it emphasizes the clarity and color of the stone. It has long, flat planes that create a hall of mirrors effect that can be less brilliant but more dramatic.
Cushion Cut: This cut combines the round brilliant and square shapes to create a pillow-like appearance. It is known for its brilliance and fire, but the way it reflects light can vary depending on the number and size of the facets.
Oval-Cut: This cut elongates the stone and creates a unique play of light within the gemstone. It has similar brilliance to the round brilliant cut but with a more unique shape.
In a nutshell, different gemstone cuts affect the brilliance of a gemstone in different ways, depending on the number, size, and arrangement of facets within a gemstone. The right cut for a particular gemstone will depend on the desired effect and the characteristics of the stone itself.
Clarity is another noteworthy factor that affects brilliance and is a measure of how many internal or external imperfections a gemstone has, such as inclusions or blemishes. In general, the clearer a gemstone is, the more brilliant it will appear because light can pass through the gemstone without facing any obstruction.
Here are some ways in which clarity can affect a gemstone's brilliance:
Inclusions: If a gemstone has inclusions or other internal flaws, these can interfere with the way light passes through the stone. Inclusions can scatter or block light, making the gemstone appear less brilliant. However, in some cases, inclusions can create a unique visual effect known as a "rainbow" or "sparkle" that adds to the stone's beauty. The lesser the inclusions, the more brilliance a gemstone exhibits.
Blemishes: Blemishes are external imperfections that can also affect a gemstone's brilliance. Scratches or chips on the surface of the stone can cause light to reflect unevenly, reducing the stone's brilliance.
Transparency: The transparency of a gemstone is another crucial factor that affects its brilliance greatly. Transparent gemstones, such as diamonds, allow light to pass through them easily, resulting in high levels of brilliance. Opaque gemstones, such as turquoise, reflect light back to the observer, creating a different type of visual effect.
The bottom line here is, clarity can have a significant impact on a gemstone's brilliance. A clear, transparent gemstone will generally be more brilliant than one with inclusions or blemishes that scatter or block light. However, in some cases, imperfections can create a unique visual effect that adds to a gemstone's beauty, making clarity just one of several factors to consider when evaluating a gemstone's overall brilliance.

The color of a gemstone can also affect its brilliance. The way that light interacts with the colors of gemstone can greatly impact its overall visual appeal and brilliance.
We have compiled different ways in which color can affect a gemstone's brilliance:
Saturation: The intensity or saturation of gemstones color can also affect its brilliance. Highly saturated colors can create a more vibrant appearance, while lighter or less saturated colors can appear more subdued. Generally, gemstones with deeper, more saturated colors tend to be more brilliant than those with lighter, less saturated colors.
Hue: The specific hue or color of a gemstone can also impact its brilliance. For example, red, orange, and yellow sapphire tend to appear more brilliant than blue or green gemstones. This is because the red, orange, and yellow colors have longer wavelengths and are more easily absorbed by the human eye, creating a more intense visual effect.
Transparency: A gemstone's transparency can also impact the way that its color is perceived. Transparent gemstones allow light to pass through them, highlighting the stone's color and creating a more brilliant appearance. Opaque gemstones, on the other hand, reflect light back to the observer, creating a different type of visual effect.
To summarize everything in minimal words, the cut, color, and clarity of a gemstone can have a massive impact on its brilliance. The saturation, hue, and transparency of a gemstone can all affect the way that light interacts with it and the overall visual effect that it creates. When selecting a gemstone, it is important to consider not only its clarity and cut but also its color and the way that it complements your personal style and preferences.
