    What are Triple Excellent Certified Diamonds?

    What are Triple Excellent Certified Diamonds & Super Ideal Diamonds?

    Very sparkly diamonds!
    Well that’s the short answer, here is the long one:

    For the credible major international grading laboratories (such as G.I.A.), triple excellent & hearts and arrows cuts are some of the highest possible gradings they can give for diamond performance. Excellent for polish, excellent for symmetry and excellent for overall cut grade. The way a diamond is cut will influence its radiance, sparkle and general beauty. In GIA triple ex certified diamonds you can’t always see the difference with the naked eye unless you compare it to a diamond with a much lower grade.

    Hopefully this will not bore you too much but here are some technical terms. The areas that need to be looked at in order to grade it are the table and depth percentages, crown and pavilion height, depth and percentage, star and pavilion facet lengths along with girdle thickness. It is crucial all these factors fall within certain parameters to ensure you are purchasing the ultimate Triple Excellent cut diamonds with brilliance and light return. They may well be a bit more expensive as often more diamond is wasted in the cutting process to ensure the correct angles and facets.

    When you purchase a Triple Excellent diamond from a credible source, you receive the assurance of knowing you are buying a ‘beautifully sparkly diamond’! I also believe the diamond should be visually inspected (by an expert in diamond grading, like myself!) as well as have the matching certification to be even more reassured. A diamond is after all one of the biggest investments in ones life and it is important to feel reassured and happy that you have made the right decision.

    If you don’t mind investing even more for your sparkly diamond you may be interested in the ‘super ideal’ cut diamond. They are cut to “ideal proportions” with superior optical symmetry, polish and a specific faceting pattern. When all these factors are in harmony a distinctive “Cupid Effect” which is a visual pattern of 8 love heart shapes while looking down through the pavilion and 8 arrows when viewing the diamond from the table up position. A special Hearts and Arrows magnifying viewer is used to show this effect. It is interesting to note that ‘Less than 1% of the world´s rough diamond crystals are pure enough to become a hearts and arrows diamond. Using 100X magnification and analysis through all stages of production, the artisanal cutters create perfection at 10X global standards for grading and evaluation. A Hearts and Arrows diamond takes up to four times longer to cut than other diamonds’.

    I hope this helped to clear up any confusion that might arise when buying round brilliant cut diamonds and optimum sparkle & performance! At Orisni Jewellers we believe the cut, symmetry and polish of the round brilliant cut diamond is very important, as well as the diamonds clarity & colour.
