The Marquise cut diamond is one of the more elegant and traditional diamond shapes. The Marquise is a slim oval shape with tapered pointed tips. The Marquise is a heavier stone than many others – while a rough diamond will produce a round brilliant diamond of a certain size, when cutting it into a marquise shape, it will generally produce a diamond up to 50% larger in carat size.
Another factor that you have to consider when purchasing a princess cut diamond engagement rings is the clarity. The clarity of a 鑽石淨度 is the measure of the number of flaws that exist within the diamond. Inner flaws often occur during the process when the diamond is being cut and formed. A diamond that has very few flaws is said to have higher clarity, which can also increase the brilliance of the diamond because there are fewer opportunities for blocking the light that passes through it.
The reason that diamond color is so important to diamond professionals is that the whole issue of diamond value is a matter of rarity. The rarest stones will always command the highest prices. The completely colorless D diamonds are extremely rare. There are very few stones, especially larger ones, which show this diamond color, and so dealers and collectors are prepared to pay enormous prices for them. But this has nothing to do with the appeal of the diamond to the ordinary buyer. It may even be that you are attracted to a frankly yellowish diamond at the Z end of the scale. If you are, go ahead and buy it: you’ll have found yourself a real bargain, no matter what the experts say.
In this final step, the diamond is placed in a clamp and polished with another blade coated in diamond dust. This blade does not contain the same amount of roughness that the other blades. Think of the difference between a coarse metal file, and fine sandpaper. This gives the diamond a shiny finish as opposed to a scratched one.
When the culet is left open, or polished to a flat facet, it can be a large culet or a small culet. That measurement is basically telling you how flat they polished the point – a large amount of surface area or maybe they left it fairly pointed with only a small amount of surface area.
A diamond cutter will first evaluate the rough stone to determine the cut style. His goal is to keep the amount of diamond waste to a minimal. Once the shape is determined, the cutter will decide on the height, shape and length of the diamond. Technology enables a cutter to create a model that shows how the diamond will look before the cutting begins. This tool helps the cutter in determining the best diamond shape.
When you are choosing the right diamond cut, you don’t have to limit yourself to the ordinary run of the mill cuts. You should consider more creative options if you are looking for a unique ring to express your love. A heart shaped diamond makes for one of the most beautiful engagement rings you can have. It stands out with its unique shape, and its facets and cuts reflect the light beautiful as well as show off the best qualities of the diamonds. It will certainly be something for you to remember and cherish as you look down on the ring on your finger all the time.
