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 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.
The most brilliant, or sparkliest, diamond cut is the round brilliant cut. Round brilliant stones are cut to have 58 facets (including the culet), allowing light to enter the diamond and reflect off of every facet to create a beautiful sparkle.
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.
The way each of a diamond's tiny facets are cut and polished determines how much sparkle the diamond will have, which means the style and quality of cutting and polishing are equally important. More facets create more sparkle, and to achieve maximum sparkle, each facet must be cut and polished properly.
Keep the diamond clean.
This is probably the most important (and affordable) tip. A diamond that's dirty will not sparkle. Diamonds have an affinity for grease, so it's important to clean them regularly. Find out how to keep your diamond clean.
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.
D color diamond is the highest grade and is extremely rare—the highest color grade that money can buy.
The best diamond clarity grade is FL, flawless.
By contrast, although white (not clear, but diamonds with a milky-white tone) and black diamonds are quite rare, they have not managed to capture the favour and attention of the public and are considered to be the least valuable of all coloured diamonds.
1. ROUND BRILLIANT DIAMOND. By far the most popular cut is the Round Brilliant, with it's fifty-seven perfectly aligned facets it's brilliance really does out-shine the others. Total internal reflection is the key here; light travels through the stone giving optimum sparkle and scintillation.
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.
AGS 0: Flawless or Internally Flawless
Flawless diamonds have no inclusions or blemishes visible under 10x. Internally Flawless diamonds have no inclusions visible under 10x, but can have very minor blemishes (marks and features confined to the surface only).
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.
Light produced by LEDs casts a crisp, clean and clear beam that bring out the brilliance in stones. You see, diamonds and other stones reflect light and when light is reflected from them, their colors and cuts shine with utmost clarity.
1. The Cullinan Diamond. The world's biggest diamond is the Cullinan Diamond, discovered in the Premier Mine in South Africa in 1905.
Tiffany only accepts engagement diamonds in the “colorless” and “near colorless” range on a diamond color scale. For engagement diamonds, Tiffany only accepts D, E, F, G, H and I color diamonds. Fancy color diamonds such as yellow or pink diamonds have their own color grades.
A VS1 diamond has slightly fewer and smaller inclusions than a VS2 diamond. In other words, a VS1 diamond is slightly better than a VS2 diamond.
Which Diamond Color Is The Most Expensive? Despite the popularity of white diamonds, red diamonds take the prize for the most expensive diamond color. This is primarily due to their rarity. Red diamonds also differ in the source of their color from other colored diamonds.
Near colorless diamonds, (G, H, I, and J grades,) are the best value in diamonds. G color is just one step down from the truly Colorless tier, so it still appears very colorless. H color is another good “near colorless” choice and is, in my opinion, the last color grade where yellow or brown is not visible face up.
In terms of clarity, the most popular range for a diamond engagement ring is the VS1-VS2 diamond. Color is also a factor to consider when thinking about clarity. For example, it will be much easier to spot imperfections in a very clear white diamond than in a yellow diamond.
The first in the faint tint range, K color diamonds have a slight yellow tint that's visible even to the naked eye. L color diamonds have a yellow tint that's visible to the naked eye, and M color diamonds have a definite yellow tint that's visible to the naked eye.
We all love how a diamond shines in the sunlight. Test your stone by putting it in direct sunlight and examining the colors it reflects. A real diamond will reflect both rainbow colors as well as white light. If you only get one of the two, then the diamond isn't real.
Diamonds come in many colors. Diamonds that range from colorless to light yellow and brown fall within the normal color range. Within that range, colorless diamonds are the most rare, so they're the most valuable.
