At Variation, our 1 Carat Round Cut Lab Grown Diamonds collection is curated for those who value precision cutting, IGI-certified quality, and consistent light performance in every stone.

    Understanding 1 Carat Round Cut Lab Grown Diamonds — U.S. Buyer’s Overview

    What Makes the Round Cut the Standard for Brilliance?

    The round brilliant cut is designed for maximum light return. With 58 precisely arranged facets, it produces strong brilliance, fire, and scintillation. In a 1 carat diamond, these optical advantages are especially noticeable, making the round cut a leading choice for buyers who prioritise sparkle and symmetry.

    Variation’s 1 carat round cut lab grown diamonds are created using:

    • CVD (Chemical Vapor Deposition)
    • HPHT (High Pressure High Temperature)

    Both growth methods produce diamonds with the same chemical composition, crystalline structure, and hardness as mined diamonds, ensuring identical brilliance, durability, and long-term performance.

    Customers choosing Variation benefit from:

    • Maximum brilliance and fire
    • Excellent symmetry and balanced proportions
    • Reliable durability for long-term wear
    • Verified quality through IGI certification

    2. Greater Value with Higher Quality Options

    Understanding the 4Cs in 1 Carat Round Cut Lab Grown Diamonds

    Carat Weight

    At 1 carat, the diamond provides a clear visual presence while maintaining a refined look. Exact millimetre measurements vary based on cut proportions, which is why measurements matter alongside carat weight.

    Color

    Most buyers select between D and J color grades for a bright, clean appearance. The round cut’s brilliance helps minimise visible color, making it forgiving across a wider range.

    Clarity

    Clarity ranges from flawless to slightly included. The round cut’s faceting can help disguise minor inclusions, allowing buyers to balance appearance and value effectively.

    Cut

    Cut quality has the greatest impact on sparkle. Well-cut 1 carat round diamonds show strong light return and balanced symmetry, resulting in a consistently bright appearance.
