Eternal Flame Diamond Journey

Only 0,01% of diamonds in the world are eligible to be Eternal Flame Diamond

Eternal Flame Diamond Journey
  • RAW & NATURAL DIAMOND

    Owning a natural diamond is like having a piece of history. Formed in the Earth's core by extremely high temperatures and pressures, it takes 1-3 million years of volcanic movement to bring diamonds to the Earth's surface. This makes diamond the strongest and most valuable mineral on earth.

  • DEFINITE DIAMOND

    Natural diamonds are mined and cut to international standards. However, to find the Definite Diamond among the mined diamonds, we selected diamonds based on 18 varying parameters from color, clarity, to strict standards of symmetry and cutting precision above internationally approved criteria. This ensures that each of our Definite diamonds has the most beautiful sparks. Adelle's high standards and requirements make only 0.01% of the world's diamonds eligible to be Definite Diamonds.

  • ETERNAL FLAME DIAMOND

    In search of the most beautiful diamond in the world, Adelle finds a diamond with a fire that captivates anyone who sees it. We worked closely with America's leading Diamond Light Performance institution, GemEx, to select Definite diamonds that have been graded to Adelle's very high standards. Only the most beautiful diamonds with the best fire, brilliance and sparkle can earn extra certificates for light performance from Gemex. This diamond, which is extremely rare and has unparalleled beauty, is called the Eternal Flame diamond.

  • certificate 0

  • certificate 1

    GemEx is a certification laboratory located in America that specializes in scientifically studying & analyzing diamond "light performance" - how light reflects off diamonds & shines through diamonds. GemEx was invented by two electrical engineers who saw a flaw in the diamond industry where at the time, there was no precise way to measure the beauty of diamonds. Consumers have to believe their own eyes. GemEx certification indicates a diamond's light performance or measures the amount of light reflected by a diamond. Light Performance is known as the element that is responsible for giving the diamond its beauty.
