Why You’ll Love It

 

 

  1. Unique Heptalogy Design

    The name “Heptalogy” refers to the seven-stone composition—one oval center and six marquise side stones—symbolising unity and never-ending love. Each marquise is precisely angled to create a halo of light around the center, amplifying brilliance from every angle.

  2. Customizable to Your Taste

     

    • Diamond Choice: Opt for a lab-grown diamond (identical to earth-mined in clarity and sparkle) or choose a natural diamond if you prefer a timeless heirloom.

    • Metal Finish: Warm yellow gold whispers tradition; white gold offers versatility; platinum delivers unmatched durability.

    • Sizing & Carats: Select your perfect carat sizes to match your personal style and budget.

     

  3. Ethical & Sustainable

     

    • Every lab-grown diamond option is eco-friendly, produced with minimal environmental impact.

    • Natural diamonds are hand-selected from conflict-free sources, ensuring you own a piece with a transparent origin.

     

  4. Expert Craftsmanship

     

    • Hand-set by our master artisans at Raphana Jewellery, each ring undergoes meticulous polishing, prong adjustment, and quality checks.

    • The contoured band is gently tapered for comfortable all-day wear, while the elevated cathedral setting enhances light performance.
