Buyers Guide: Factors to Consider for Your Diamond Jewellery

Polish and Symmetry 

Polish is the smoothness of the diamond’s faceted surface. Polish does not affect a diamond’s value, but it has a HUGE effect on its appearance! 

A poorly polished diamond looks dull and lifeless, while well-polished facets make light return to the eye much better, giving the gem more life. 

High-quality diamonds should bring out their maximum fire, brilliance, and scintillation. The polishing process has significantly improved with computer-controlled equipment. 

Also, there are six facets to every diamond, including table, crown, girdle, pavilion, culet, and star. All these have to be cut symmetrically and polished to perfection.


Fluorescence denotes the glow that diamonds emit when subjected to ultraviolet radiation. Fluorescence does not affect the diamond’s color grade, based on a completely different phenomenon, but it strongly impacts its value. 

Strong fluorescence makes diamond necklaces appear hazy and milky under certain lighting conditions. It does not affect the color but certainly how much you will enjoy it! 

Fluorescent diamond jewelry is worth considerably less than non-fluorescent ones of equal color and clarity grades.


Diamonds fall into the following categories concerning their inherent body color:

  • Colorless diamonds– These are rated D through F on the diamond grading scale. The closer a diamond gets to colorless, the higher its value. The scale goes from D (completely colorless) to Z (light yellow or brown). 
  • Yellow – Yellow diamonds are naturally colored by nitrogen impurities. The more intense the yellow, the higher is its value, e.g., yellow fancy colored diamonds.
  • Gray – Gray diamonds lack the element boron. These diamonds are rare and can be as valuable as some yellow diamonds.
  • Green – Green diamonds come from exposure to radioactive elements such as uranium. Such diamonds are extremely rare and will probably not be available for sale unless you find a very old jewelry collection.

Carat weight is the most obvious feature of a diamond, and many people assume that bigger is better. This can be true if your budget isn’t limited, but it shouldn’t be the only factor in your buying decision. 

Diamond size depends on the cut, color, and clarity grades, not carat weight. The value of a diamond increases exponentially with its size. It’s amazing how much beauty you can get from even 1/5th or 1/10th of a carat of precious stones.


The clarity of a diamond determines its value. Jewelers observe the number, nature, and position of blemishes or flaws on the diamond’s surface to determine clarity in diamonds.

How this affects their appearance depends on how noticeable these features are, depending on size, placement, and contrast with the surrounding area. 

Diamond grading is very strict, which means that even the smallest flaw can affect the clarity grade. Flaws located at the center of the stone are more visible than those near the edge, so flaws should be on flat or culet facets.
