You see, diamonds are a magnet for grease/oil as their surfaces muck up easily. A dirty stone doesn't sparkle because light simply can't enter the diamond and causes it to appear dull.
A real diamond provides an exceptional sparkle since it reflects white light extremely well. In addition, diamonds can also reflect fire or colored light in a beautiful display. Compared to a stone like Cubic Zirconia, you'll be able to see a huge difference in the white and colored light sparkle.
Your ring needs regular cleaning. Cleaning your diamond with a solution of water and mild dish soap once a week will keep it looking sparkling and new. Avoid using chemicals in cleaning products. Get your ring checked out by a jeweller.
For each individual diamond, there are specific proportions that will make the diamond sparkle at its best, and it is far better to have an Ideal-cut diamond that is 0.90 carats than a poorly cut diamond that is 1.00 or 1.10 carats. A good cut will result in a better sparkle.
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.

Certain types of inclusions and graining can sometimes reduce transparency in a diamond to a noticeable degree. If transparency is degraded enough, the diamond can appear obviously cloudy or milky and lacking in luster. In other cases, the effect is subtle and may not be noticeable to any but the most trained eye.
Refraction creates a sparkle in a diamond as a result of light bouncing around the inside, which hits your eye when the stone is in motion. The brightness, or brilliance, of light that exits through the top of a diamond is a result of both reflection and refraction.
Excellent: This is the highest grade, representing the top 3% of all diamonds in the world. Diamonds with an excellent cut grade are masterfully crafted and precisely cut to create maximum sparkle and brilliance. Little or no light leakage occurs as light passes through.
Uncleanliness – An uncleaned diamond may appear hazy or cloudy to the naked eye, especially when coated in oils. It's important to know how to clean diamonds properly to avoid a cloudy appearance.
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.
Color also has a big impact on the sparkle produced by a diamond. 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.
They do NOT dull or stop sparkling, they just get dirty. Diamonds are magnets for all kinds of materials which will stick to them and make them lose their sparkle. Finger prints are a prime example. The oils on your fingers can stick to the diamond and make it lose some of its brilliance.
And if maximum sparkle is your aim, consider a pavé band paired with a solitaire stone in a prong or cathedral setting. The addition of smaller diamonds, especially on the shank, will illuminate your ring from all angles and give the illusion of a strikingly bright ring.
The bezel setting comprises of a rim of metal which secures the diamond by its circumference. Since it follows the outline of the stone, the shape of the center stone is enhanced and appears larger than it is.
Diamonds need to be cut and polished to enhance their appearance before being made into jewelry, and this process gives diamonds the many facets they need to catch the light and send it glittering in every direction.
The cheapest diamond cuts basically, in two Diamond gemstones i.e. Emerald Diamond cut and Asscher diamond cut. These two cuts are very cheap.
In general, the deeper the cut of the stone, the duller it is. Moreover, deep cut diamonds look smaller than ideal cut diamonds of the same carat weight when set in a mounting. This effect appears because the cutter sacrifices the stone's width to achieve a greater depth.
