Buying Guide
What to consider when choosing between 2 carat and 1 carat options
- Brilliance and size perception: Halo and princess settings can make a smaller stone appear larger; opt for halo or chevron settings if you want visual impact without a higher carat weight.
- Certification and sourcing: IGI vs. IGI-certified vs. other labs may influence perceived color and value. Consider your comfort with certification type in purchasing decisions.
- Metal and durability: 14K white gold offers a durable, hypoallergenic finish. If you prefer a heavier, more lasting mount, consider higher karat options or platings that match lifestyle needs.
- Wearability and daily use: Four-prong settings provide secure hold for everyday wear, but claw styles may require periodic tightening. Halo surrounds demand careful cleaning to maintain sparkle.
- Ethics and environment: Lab-grown diamonds reduce environmental impact relative to some mining practices. Zero-conflict claims align with responsible-consumer goals.
FAQ
