So, let’s go over the factors that affect diamond brightness. We’ll first start with clarity and move on from there. Clarity A diamond’s color is graded by the Gemological Institute of America, which uses letters from D to Z to grade its color. The more colorless the diamond, the higher its quality. Diamonds with the color grade D are nearly colorless, whereas diamonds on the lower scale have a more intense yellow tinge.

The radiant cut is very similar to round and emerald cuts. However, radiant cut diamonds feature 70 facets. While these diamonds don’t have intense brightness as other diamonds on this list, they offer superb sparkle and brilliance. Oval Cut

Undoubtedly, diamonds are the stars of many of the world’s most beautiful pieces of jewelry. But what makes these precious gems shine the way they do? Sawing– The cutter uses a rotating phosphor-bronze blade to cut the diamond in the places where it’s not weak. That is when they decide which part will become the table and which the girdle.

Most diamond inclusions are tiny and not visible enough to affect their brightness directly. Unless you’re looking at a diamond with a visible inclusion, the impurities inside it don’t affect how light travels through it. Color Just like round-cut diamonds, pear-cut diamonds feature 58 facets. As their name suggests, these diamonds are shaped like a pear. Unfortunately, pear-cut diamonds aren’t as bright as other cuts, but they make up for it with their unique shape. Heart Shape You can clean it once or twice a week, using water and mild dish soap. We recommend using a toothbrush to remove eventual remaining dirt in the hard-to-reach places gently. Then rinse the piece with clean water and dry with a soft, lint-free cloth. Don’t forget to close the drain if you’re trying this over a sink! The Gemological Institute of America has standardized grading of diamond’s colors on a D to Z scale. The Institute also uses the mentioned scale but for lab-grown diamonds. All diamonds on this scale are considered white, even though they may have a tinge of yellow on the lower end.

Tavernier noted there were European professionals that received the most prominent stones for processing. Still, it’s unknown whether they perfected the trade with the help of Indian artisans – or they came there with superior knowledge. After a diamond has been carefully cut to reflect and refract light as well as possible, the diamond must be polished so that light is not scattered as it leaves the diamond. The diamond polisher removes any external blemishes as far as possible. Just like many other things, a well-polished diamond will bring out the shine and brilliance of the object. That means diamonds have to be mined and don’t look impressive when found – they have a rough, opaque coat that needs processing first. They genuinely aren’t much to look at when they’re first mined.Certain diamond cuts provide more brightness than others. In most cases, diamonds with more facets are the brightest. However, this isn’t always necessarily better. Quite the contrary, the ideal number of facets on a diamond is exactly 58.

The cutter must direct the rays up to the top for brilliance but also across the diamond body – so that it looks as if they’re “skipping” between the internal walls. Such alignment of the light waves is referred to as sparkle. These cuts are made to enhance the diamond’s brilliance by using its natural properties and complex angles. This way, diamond cuts don’t just provide superb gleam but also assure the diamond’s shape is aesthetically pleasing. Symmetry This silicone-based tyre shine leaves a wet-look gloss that lasted a good few days, if not as long as some of our others. It’s of the ‘spray and leave’ school of application but doesn’t drip as much as some others and is easy to apply neatly. It did a good job of restoring the depth of colour to some faded trim when we applied it using a microfibre, too. Good all-rounder, but not the best value option.

Diamonds are known to be natural magnets for grease – so, even holding a diamond with your fingers could lead to enough build-up on its surface to reduce its brilliance and fire. Although these dark areas might seem counterproductive, they’re the “secret sauce” needed to achieve the diamond’s trademark shine. Reflection is a fancy word for the light that hits the diamond and immediately gets reflected, giving it its signature shine. Although this glimmer is impressive on its own, it’s only the tip of the iceberg of the true radiance a diamond can display.
