For decades, Triple Excellent (3EX) has been known as the industry standard but LUMOS by ZCOVA Diamonds take it to the next level. In addition to Excellent Cut, Symmetry, and Polish, a diamond must also achieve 'Ultimate' grade in Light Performance in order to qualify as a LUMOS by ZCOVA Diamond.
This distinct combination of exceptional quality and superior brilliance, a grade referred to as ‘super ideal cut diamond’ in the market comes at no extra charge.
Only 1 in a thousand diamonds make the cut to become LUMOS by ZCOVA Diamonds - make this rare beauty exclusively yours.
While the 4Cs (carat, cut, colour, and clarity) have traditionally been used to evaluate diamond quality, Light Performance adds a new dimension to diamond grading. The way a diamond reflects and refracts light is what makes it sparkle and shine, and this can only be accurately measured through advanced technology such as Sarine's imaging.
All LUMOS by ZCOVA Diamonds are graded by GIA and then analysed by Sarine to scientifically evaluate the diamond’s Light Performance, ensuring that each diamond is of the highest quality.
Sarine light performance grade is the world’s most reliable, accurate and objective grading of the diamond’s visual beauty, brought to you by Sarine Light™, the leading light performance measurement technology.
Sarine measures and grades each diamond according to 4 parameters: Brilliance, Fire, Sparkle and Light Symmetry. These make up a diamond's Light Performance and beauty.
While most diamonds in the market can achieve Classic or Premium Total Grade, only the rarest diamonds have the 'Ultimate' light beauty and are selected to be LUMOS by ZCOVA Diamonds.
