Deep Cut

This diamond appears smaller than it weighs because iii; weight is retained in the depth. It is cut with a deep pavilion (bottom of the diamond) that does not properly reflect light

back through the crown (top of the diamond) producing a dark I

appearing diamond that lacks beauty. These diamonds are I\

sometimescalled nail heads due to their dark, face-up \ \

appearance. \

Diamonds that are cut with shallow pavilions that do not properly reflect light back through their crown producing a washed-outor watery appearance. Weight is retained in the diameter, making the diamonds appear larger than theyweigh. These diamonds are sometimes called fisheyes, due to

  DIAMOND

  A P R I L

  Engagement diamonds have been worn on the third fingerof the left hand, for Egyptiansbelieved the "yein of love" connected this finger to the heart. Until the 15th century only royalty, nobility, and priests were allowed to own and wear diamonds.Sincediamonds are unique, precious and invincible they represent lasting loveand the symbol or pledgebetween two people. Diamond is from the Greek word "adamas" meaning unconquerable and they are principallyfound in SouthAfrica, Botswana, Zaire, Russia,Australia,and Canada.

  
  

  RobertM. Shipley,who founded the Gemological Instituteof American (GIA) in 1931, alsofounded the American Gem Society (ACS) in 1934.The mission of the American Gem Society is to promoteethics, knowledge, and consumer protection.Throughout the world there are many diamond grading systems. Only the ACS and GIA systemsqualify and quantifygrades with specific and accurate termsdetailing the grading factorsfor a diamond.

  THE FOUR Cs

  The four Cs;Color,Cut, Clarity,and Carat Weight, are factors thatwill help you make an intelligent choice withconfidence. Cut, color, and clarity are quality or rarityfactors. Though some aspects of quality seem subtle, they may have a major impact on value.Carat weight isa value factor.When making a purchase,a consumer must balance the three quality factors with size to obtain the best value within their budget.

  
  

  CUT

  In itsrough state,a diamond's beauty is well concealed. Cuttingrevealsits magnificent opticalbeauty. Adiamond cutter'schallengeis to balance beauty with weight retention from the rough diamond crystal.In thebest-case scenario, approximately 50% of the weightis lostfrom the original crystal in the cuttingproces.sBecausesize is important to many consumers, oftencutterssacrifice diamond beauty

  in order tosave weight,maximizing the size of the finisheddiamond.

  
  

  Shape and cut arenot the same. Diamonds are cut in many shapes: round brilliant, pear, oval, marquise, emerald cut (rectangular),heart, and triangle. The most popular shape is the roundbrilliant.The other shapes are referred to as fancy-shape.s

  
  

  Tn the past diamonds were analyzed, not graded, for cut by visualestimation. Today, theanglesand proportionsrelating to the quality of cut are determined electroncially. A diamond's finish, including polish and symmetry,is graded by human examinationthrough a binocular microscope.

  CLARITY

  This is the presence or absenceof inclusionswithin the diamond and blemishes on itssurfaces. A diamond'sclarity gradeisdetermined through examination by an experiencde

  grader,usinglOx magnification and also the assessmnet of the

  
  

  CARAT W EIGHT

  This isa measurement of weight used in determining rarity in evaluating a diamond. In theearly 1900sthe Metric Carat was established: 1 Carat = .2 Gram.

  Thereare100 Points toa carat. The FTC tolerance for what is rounded up is1/2 point. For example, .995 = 1.00 carat. The AGS uses the internationaldiamond standardtolerance for rounding with is 1/10 point. For example, .999 = 1.00 carat.

  A full carat is a diamond that weighs or rounds to1.00carat. A light carat isa diamond thatweighs slighlty less than 1.00 carat.Example .96 - .99. This IS NOT a full carat. Magic size diamonds are thosethat weigh-in exactly at or greater than a major sizecategory.

  Carat weight usually has the greatest impact on value, based on rarity. Most fancy-shapeddiamondsare elongatedin shape and appear largerthan a comparable round brilliant diamon.d In addition, in most cases, fancy-shapeddiamondsare priced less than round brilliants.

  A diamond grading report is an expert third-party opinion of the diamond quality.The diamond grading reportcontains information on identification, enhancemnets, carat weight, shape outline, measurements,color, clarity,and cut. A consumer can then insurethe diamond for replacemetnin case of loss or theft.

  COLOR

  This is the amount or presence of body color in a diamond. The most rarediamond colorsare red, pink, green, and blue. Diamonds that display enough of a hue,or nuanceof color to be desirable,are called fancy-coloreddiamonds.

  
  

  The absence of color in diamonds is most rare and highly prized. Most diamonds mined in nature have tracesof yellow, so me brown or gray. The range of color most often represented and sold in jewelry storesarc: AGS grades O - 3.0and GIA

  According to the Federal Trade Commiss ion, onlya diamond that is flawless,colorless and well cut can be referred to as "perfect." Therefore, it is NOTapplicable in most cases.

  
  

  Diamondis99.9%5 pure carbon,and 25 different mineral inclusions or small crystals, have been found within diamond. These are not carbonspots, but rather small crystals that were
