1 Carat Heart Lab Grown Diamonds – The Ultimate Symbol of Love
A 1 carat heart lab grown diamond is the truest expression of love — blending romance, artistry, and precision. With its beautifully curved lobes and defined point, the heart cut symbolizes affection, devotion, and emotional connection. It’s a timeless choice for those who believe love should shine forever — beautifully and responsibly.
At Variation USA, we offer IGI-certified 1 carat heart lab grown diamonds crafted using advanced CVD (Chemical Vapor Deposition) and HPHT (High Pressure High Temperature) technology. Each diamond radiates the same brilliance, durability, and purity as mined ones — ethically created for the modern world.
Why Choose a 1 Carat Heart Lab Grown Diamond?
The heart cut diamond is a masterpiece of symmetry and emotion. Crafted from the brilliant cut family, it offers exceptional fire and sparkle, enhanced by its romantic shape.
A 1 carat heart diamond is the perfect size for showcasing the iconic silhouette without overpowering — ideal for solitaire pendants, engagement rings, or special keepsakes. When lab grown, it retains all the chemical, physical, and optical properties of mined diamonds, while being ethical, sustainable, and conflict-free.
