LUMOS diamonds are a collection of mined diamonds curated for their superior quality and brilliance, graded by GIA and GemEx. ZCOVA is the only online diamond brand in Malaysia and Singapore to guarantee brilliant diamonds with dual certificates from GIA & GemEx.
Certified diamonds have been graded by an independent laboratory such as GIA to determine the 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 diamond grading report so you’ll know exactly what you’re purchasing.
GemEx is the worldwide leader in the certification of diamond brilliance, fire and sparkle, which measures a diamond’s beauty. GemEx uses advanced imaging and lighting technology to analyze the light performance of diamonds.
GIA (Gemological Institute of America) is the world’s leading independent gem and jewelry educational organization that grades diamonds based on the 4Cs which are carat, colour, clarity and cut.
