Features of elegant premier rose diamond :

It is a D-colored, pear shaped stone, weighing 137.02 carats with the highest degree of purity. Usually the nitrogenous impurities impart color to the stone and affect the clarity. This exotic stone is free from impurities such as nitrogen and boron; hence it is pure and colorless. This massive stone is categorized under type II diamond, owing to the chemically pure and structurally perfect nature. It is the 3rd largest pear-structured, D- colored diamond in the world. The stone was cleaved and polished into three parts, the big rose (137.02ct), little rose (31.48ct), and the baby rose (2.11ct). This sparkling stone is referred as "cleavage piece" since it does not possess a definite crystallographic structure. The plastic deformation during eruption phase in the kimberlitic process caused orthogonal inversions on one of the hexahedral faces of the stone, which resulted in crystallographic orientation. Due to its phenomenal qualities, it became the bench mark for pear cut diamonds.
