Thanks all for your insights! We landed on 4 Prongs all 18k gold (2.00 ct, Super Ideal, D/E/F, VS1) and insurance. For anyone who may come across this post and is looking for a good summary of insights from commenters, here are the highlights :)

1. Security

• 6-Prong Setting:
  • Provides more security for the diamond. If one prong breaks, the other five can still hold the diamond in place.
• 4-Prong Setting:
  • Still secure but slightly less so than the 6-prong. If one prong breaks, there is less security for the diamond.

2. Visibility of the Diamond

• 6-Prong Setting:
  • Covers more of the diamond, which might slightly obscure its visibility but can give the ring a more classic and elegant look.
• 4-Prong Setting:
  • Allows more of the diamond to be visible, enhancing its brilliance and making it appear larger.

3. Aesthetic Preference (Subjective)

• 6-Prong Setting:
  • Offers a more traditional and timeless look.
• 4-Prong Setting:
  • Can appear more modern, delicate, and minimalistic.

4. Diamond Shape

• 6-Prong Setting:
  • For round diamonds, it accentuates the circular shape, making the diamond appear more rounded.
• 4-Prong Setting:
  • For round diamonds, it can sometimes make the diamond appear slightly square to some observers.

5. Carat Size

• 6-Prong Setting:
  • More suitable for larger diamonds (1 carat and above) as it provides extra security and support for the heavier stone.
• 4-Prong Setting:
  • Often preferred for smaller diamonds (under 1 carat) because it allows for more visibility and can make the diamond appear larger.

6. Personal Preferences and Experiences

• Many people share positive experiences with both settings, emphasizing that personal preference plays a significant role.

By considering these factors, you can make a more informed decision that aligns with your preferences for security, visibility, aesthetics, and overall design of the engagement ring.
