About Round Cut Lab Grown Diamond Rings
Round Lab Grown Diamond Rings – Timeless Brilliance with Perfect, Classic Sparkle
Round lab grown diamond rings are the most iconic and cherished ring style worldwide — and a top favourite across Canada. Known for their 58 precisely angled facets, round brilliant diamonds deliver unmatched fire, scintillation, and symmetry. Crafted using advanced CVD and HPHT technology, round lab grown diamonds are chemically, visually, and physically identical to mined diamonds, offering the same dazzling beauty with far more ethical and sustainable origins.
At Variation Canada, our round diamond rings are crafted with IGI-certified lab grown diamonds set in luxurious 18K gold. Whether chosen as solitaires, halos, pavé bands, or vintage-inspired designs, round diamonds offer a perfect blend of tradition, brilliance, and modern ethical luxury.
