The Gitanjali Grouphas been cutting diamonds since 1966. That skill hit new heights with the perfection of cutting ideal Hearts& Arrows. The group is one of the few companies in the world that has the technology and skill-set to cut Ideal Heart & Arrow diamonds starting at 0.005 carats.

Opening in 2003, the flagship company-owned factory in China is one of the world's largest cutting facilities of ideal melee from 0.10 carats and below. Capitalizing on this unique core competency and utilizing Gitanjali's strength of superior branding, the dream of creating PassionStone became a reality.

Launched in 2006, PassionStone is one of the marquise brands of Aston Luxury Group, a Gitanjalicompany. Gitanjali's 45-years history of being a DTC Sight Holder and its world-renowned branding capabilities, have propelled PassionStone to the forefront of Ideal Cut diamond brands.Today, PassionStone is emerging as one of the premier Ideal Cut Heart and Arrow brands with over 150 retail locations worldwide. PassionStone luxurious diamonds are sold loose or masterfully crafted into contemporary bridal and fashion styles created by top designers.

Only the highest quality of rough diamondsfrom around the world qualify asPassionStone diamonds. Each stone is cutto Triple Excellent Ideal Heart and Arrow proportions. Every PassionStonediamond is strictly graded for diamondquality and measured for light performanceby Fire Trace from IGL.

Perhaps the most difficult of the 4 C's to comprehend is cut, yet it can affect the value of a diamond by as much as 40%! Cut is the only man made influence on the value of a diamond and it has the greatest impact on a diamond's beauty. Less than 5% of all rough diamonds in the world can be cut into an Ideal Cut Diamond.

Perfect in proportion and symmetry to reflect maximum light though the diamond;master diamond artisans with the latest technology and cutting techniques can only sculpt the ideal cut.

In 1919, a Belgian mathematician named Marcel Tolkowsky published calculations for cutting a round diamond to optimize brilliance. This came to be known as the "Ideal Cut". This proportion based definition of ideal was the unchallenged standard for almost 80 years until technology advanced far enough so that light performance became a significant criteria in determining an "ideal" diamond.

Fire trace by IGL is the "predictive" scientific analysis of a diamond's brilliance, measuring the performance of light. All PassionStone diamonds MUST certify for Triple ideal Light Performance, which measures the amount of Brightness (white light), five (dispersion), and Scintillation (sparkle) of the diamond.

Brightness, otherwise known as brilliance, is the total amount of white light, both external and internal, returned from the diamond to the viewer's eye.

FIRE, otherwise known as dispersion, is the amount of color light returned from the diamond to the eye of the observer. These flashes of color are caused by the prismatic abilities of a diamond.

SCINTILLATION, commonly referred to as sparkle, is the reflections and flashes of white light from the diamond's surface as the diamond, the observer, or the light source moves.

PassionStone diamonds are put through an OGI machine, which takes a 3D analysis of the stone and provides us with the technical details such as Table %, Depth %, crown Angle, Pavilion Depth, and Girdle Thickness.

These parameters are then plugged into a sophisticated algorithm, which computes the "predicted" amount of light return that will occur and these grades are given under the brightness, fire, and scintillation categories. This algorithm has undergone rigorous testing to prove it works in the real world.
The predictive method is the most accurate measure of light performance because it eliminates the external factors (such as how the diamond is placed on the machine) and actually predicts the amount of light that will be reflected back. Under this approach, PassionStone diamonds are given a grade that can be compared, without bias, to any diamond in the world.
