LUMOS by ZCOVA Diamonds: Certified 'Ultimate' Light Performance

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.

Beyond the 4Cs

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.

Dual Certificates

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.
