  • Shallow Cut: A shallow-cut diamond will lose light through the bottom, causing it to appear dull.
  • Deep Cut: A deep-cut diamond will lose light through the diamond’s sides, causing it to appear dark.
  • Excellent Cut: Excellent Cut is considered the best cut because it will reflect most or all of the light that enters the diamond back to the eyes. 
  • The Diamond Cut is an important property,  a well-cut diamond reflects light to maximize the stone's brilliance.  A diamond with perfect color and clarity could nevertheless have poor brilliance if it is not well cut. 
  • The quality of a diamond's cut can be determined on the basis of its power to reflect light.  It is characterized as Excellent, Very Good, Good, Fair, or Poor.  Excellent cuts release the inner brilliance of the stone and project the maximum amount of fire and sparkle; whereas Very Good, Good, and Fair cuts loose some light.  A poor cut loses most of its light from the diamond sides and bottom.  You should always go for the excellent cut diamond with the desired shape. 


  • Diamond color is also a vital factor to look for since diamonds are found in almost all colors.  Most diamonds appear white to the naked eye, but they include trace amounts of yellow or brown color.  Slight differences in diamond color can make a substantial difference in value.  A truly colorless diamond is extremely rare and valuable. The diamond color scale goes from D to Z, with D being colorless and Z being the most saturated. 


  • Clarity is a term used to describe the absence or presence of flaws inside or on the surface of a diamond. It is graded under 10 power magnification.  When flaws occur internally, they are called inclusions. The most common types of inclusions include crystals, needles, knots, chips, cavities, cleavage, and feathers. When flaws occur on or break the surface, they are known as blemishes.  The most common types of blemishes include polish lines, naturals, scratches, nicks, and pits.  A diamond’s clarity is based on the number, size, nature, and location of imperfections on the finished stone.  The clarity of a diamond affects the appearance and value of the diamond. 


  • The term "carat" refers to the weight of a diamond, and 1 carat equals 0.2 grams or 1/142 of an ounce.
  • A carat may also be displayed in points, and 1 carat is divided into 100 points, therefore, a 1/4 carat diamond is considered as 25 points, and a ½ carat diamond is considered as 50 points and so on.  The price of a diamond rises exponentially with its size, so a 2 carat diamond of a given quality is always worth much more than two 1 carat diamonds of equal quality. 

Be assured with a Diamond Certificate

  • A Diamond Certificate or Diamond Grading Report, is a statement issued by an independent Gemological Laboratory.  The certificate assures that the diamond in question has been examined, measured, and scrutinized by experienced Diamond Graders and has been determined to contain the characteristics stated in the Certificate or Report.
  • The Gemological Institute of America (GIA) and the American Gem Society Laboratories (AGSL) are the main reputed laboratories available for diamond certification. Both GIS and AGSL are known for their consistency and unbiased diamond grading systems.
  • When you buy a diamond, you can always ask for a diamond certificate.  It may cost you a little more money, but it will provide you the peace of mind in knowing exactly what you are getting.
