Supplier's note

  1. Three Technical Breakthroughs:

    • Lab-Created Diamonds: Ethically sourced with identical optical properties to mined diamonds.
    • Four-Prong Setting: Reduces metal obstruction, increasing light refraction by 25% compared to bezel settings.
    • 18k Gold Alloy: Combines durability (hardness 3.5 on Mohs scale) with luxurious luster.

  2. Optimal Version Selection:

    • Base Model (10k Gold): Ideal for customers prioritizing affordability and lightweight wear.
    • Advanced Model (14k Gold): Balances cost and durability for daily use.
    • Pro Model (18k Gold): Best for collectors or formal wear due to its premium aesthetics and longevity.

Example: The Pro Model’s 18k gold ensures resistance to tarnishing, while the lab-created diamond’s flawless clarity (VVS1) creates unmatched brilliance. Pair this with the claw setting to maximize light performance, delivering a ring that outshines industry benchmarks by 30% in sparkle.
