1 Carat Round Lab-Grown Diamonds – Timeless Brilliance, Perfectly Crafted
A 1 carat round lab-grown diamond is the most iconic and universally cherished diamond size and shape. Known for its perfect symmetry, unmatched sparkle, and classic beauty, the round brilliant cut remains the top choice for engagement rings, pendants, earrings, and fine jewelry.
At Variation USA, we bring you a curated selection of IGI-certified 1 carat round lab-grown diamonds, crafted for exceptional brilliance, ethical sourcing, and guaranteed quality.
Why Choose a 1 Carat Round Lab-Grown Diamond?
1. Maximum Sparkle & Fire

2. Perfect Everyday Size
1 carat is the ideal combination of size and elegance — noticeable yet timeless, making it perfect for any jewelry style.
3. Ethical & Sustainable Choice
Lab-grown diamonds offer the same physical, chemical, and optical properties as mined diamonds — but are created responsibly, conflict-free, and with lower environmental impact.
