Zirconia is a great way to get the sparkling look of a Diamond with a noticeably smaller price tag. Like in Diamonds, the cut, quality, and colour affect the grade of cubic zirconias. AAA grade is for high-quality in symmetry, lustre and shine. The only way to Sparkle !!
It’s also worth noting that Zirconia is more durable than Swarovski Crystals and can be cut with more facets, offering a better light refraction than Swarovski crystals.
