πŸ’¬ Frequently Asked Questions

1. Is a round cut better for sparkle?

Yes. The round cut is considered the most brilliant diamond shape because of its 58 precisely arranged facets. This cut maximizes light reflection, giving it exceptional sparkle and fire β€” perfect for engagement rings.

2. Are your round lab-grown diamonds certified?

Absolutely. All our round lab-grown diamonds are IGI-certified, ensuring authenticity, quality, and grading transparency. You’ll receive a certification document with every purchase.

3. Can I customize the metal or band?

Yes, you can. We offer full customization options. Choose from white gold, yellow gold, rose gold, or platinum. You can also personalize settings, band width, and more β€” just contact us or select options directly on the product page.

4. What’s the difference between round and cushion cut?

The round cut is known for maximum brilliance and a timeless circular shape. The cushion cut has a square or rectangular shape with soft, rounded corners and a more vintage appeal. If sparkle is your top priority, round is the ideal choice.
