• DIAMOND CUT GRADE was introduced by the GIA for ROUND STONES ONLY in 2006 that’s whay you don’t generally see it listed on fancy shapes.
  • DiamondGeezer.com were one of the few UK manufacturing jewellers to be invited to the Antwerp launch.
  • Other gem laboratories have seen the need to follow, to emulate(?) the GIA and some specify cut or fancy shapes.
  • Though extremely difficult to analyse or quantify, the cut of any diamond has three attributes: brilliance (the total light reflected from a diamond), fire (the dispersion of light into the colours of the spectrum), and scintillation (the flashes of light, or sparkle, when a diamond is moved).
  • The term cut in an accurate sense defines the Diamonds make not the shape, we are talking about the contribution by man, polish, symmetry and dimensions.
  • The diamond’s cut influences its ability to handle light refraction and create sparkle, scintillation and life.
  • When diamond is well cut the facets will be in alignment and allow light to refract within the stone and be projected through the top.
  • If a diamond has a Very Good or Excellent cut then you know that the ratios are right.
  • The grading system appears to be vague adjectives but are in fact precise quality tags
    1. Ex = Excellent, ID = Ideal (different terms use by different labs, they are the same quality)
    2. VG = Very Good
    3. G = Good
    4. F = Fair
    5. P = Poor
  • Fair and Poor diamond cuts should be avoided.
  • It is interesting to see that other cutters & gemmologists are beginning to apply cut grades to other shapes, these may or may not be listed on the certificate and must be viewed as the sellers opinion.
