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.

Clarity defines the internal inclusions and or surface blemishes that a diamond may have under 10 x (power) magnification. This is actually FTC defined. These inclusions are uncrystallized diamond or carbon seen as tiny black spots in the 對戒 itself or they can be white like gas or air pockets or they can even be tiny fractures called feathers. Obviously, a feather is not a huge crack that goes from side to side across the diamond. That would be someone else’s stone, not yours.

First, walk in like a professional diamond buyer with an air of confidence. Next, start asking intelligent questions about cut, clarity, color and weight. The sales person will automatically assume you know more about diamond buying than the majority of the people that walk in the door and will be less likely to try and pull the wool over your eyes.

Good Cut is a term used when a diamond cutter creates the largest possible diamond from the original stone rather than making a smaller diamond in the Premium category. This diamond will produce beauty and quality within a budget.

How a diamond reflects light back to the admirer or owner is crucial. A diamond cutter’s goal is to get the best cut and facets to showcase the ultimate brilliance of the stone. Getting the proper proportions is one of the most important factors when cutting a diamond, and will significantly affect the value. This also determines a diamond’s fire and beauty. If the proportions are off, the stone will lack sparkle and brilliance.

Retail jewelry stores generally make a 50% markup on their diamonds. There are plenty of reputable diamond dealers on the internet that make between 7% to 15% markup on the same diamond ring.

If you do nothing else when you buy your diamond ring, please make sure that you get a certified diamond from a well respected lab like GIA or AGS. This is the best way to protect your investment.
