1 Carat Heart Lab Grown Diamonds – Romantic, Iconic & Symbolically Beautiful
A 1 carat heart lab grown diamond is the ultimate symbol of love — a perfect blend of romance, brilliance, and expressive design. Shaped with two symmetrical curves meeting at a polished point, the heart cut radiates emotion and elegance, making it a meaningful choice for engagement rings, pendants, and fine jewellery. Created using advanced CVD/HPHT technology, lab grown diamonds offer identical fire, brilliance, and hardness as mined diamonds while being ethical and sustainable.
At Variation Australia, every 1 carat heart diamond is IGI-certified, precisely cut, and hand-selected for symmetry, sparkle, and emotional impact.
