LUMOS diamonds are a collection of natural mined diamonds curated for their superior quality and brilliance, graded by GIA and Sarine. ZCOVA is the only online diamond brand in Malaysia and Singapore to guarantee brilliant real diamonds with dual certificates from GIA & Sarine.

Certified diamonds have been graded by an independent laboratory such as GIA to determine the real diamond's quality based on the stone’s carat, colour, clarity, cut and more. It is recommended that you purchase certified diamonds with a diamond certification, also known as a diamond grading report so you’ll know exactly what you’re buying, ensuring authentic diamonds.

Sarine is a technology company renowned for its advanced grading and mapping of authentic diamonds. It provides the Sarine Light Performance report, which evaluates the visual appeal of diamonds based on their brilliance, fire, and sparkle. This detailed analysis of a diamond's light performance complements traditional certification, offering deeper insight into the aesthetic value of diamonds. Sarine's cutting-edge technology is essential in helping consumers make informed decisions, emphasising the unique qualities of each real diamond.

GIA (Gemological Institute of America) is the world’s leading independent gem and jewellery educational organization that grades diamonds based on the 4Cs: carat, colour, clarity and cut. This ensures that each natural diamond meets high standards of quality and integrity.
