Eternal Flame diamonds are evaluated based on 21 parameters in terms of Diamond Quality and Diamond Beauty. These parameters are more stringent than typical diamond grading, making the Eternal Flame a rare and valuable diamond.
Only 0,01% of diamonds in the world are eligible to be Eternal Flame Diamond
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.
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 0.1% of the world's diamonds eligible to be Definite Diamonds.
ETERNAL FLAME DIAMOND
Diamonds are usually only evaluated by their quality. There is no standard assessment of the beauty of diamonds. Through Eternal Flame diamond, we want to provide not only with the finest quality diamonds, but also ensure the beauty of the diamond. 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 quality 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.

Adelle Jewellery provides certified diamonds from two of the world's leading diamond grading organizations - Gemological Institute of America (GIA) & GemEx.
Founded in 1931, GIA is the world's leading organization for diamonds, colored stones and pearls. As a not-for-profit public organization, GIA is a leading source of knowledge, standards and education in the gem and jewellery field.
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.
