Buying Guide: Princess Cut Loose Diamonds
- What to prioritize: For princess-cut diamonds, focus on carat weight, color, and clarity, but also pay attention to cut quality indicators like Excellent or Ideal cut when available, as these drive brilliance.
- Lab-grown vs. mined: Lab-grown diamonds provide eco-friendly options and often lower costs for similar color and clarity. Consider your sustainability goals and budget.
- Certification matters: IGI or similar certificates help verify grading. Ensure the certificate accompanies the stone and matches the listing description.
- Setting compatibility: Plan for a setting that protects the square corners of a princess cut. Ensure the girdle width and culet are compatible with the mounting.
- Asset tracking: When buying multiple stones, compare color and clarity grades across stones to maintain a consistent look in a multi-stone piece.
- Cost vs. performance: Higher carat weight or near-colorless ranges (D-F, VVS-VS) increase cost but improve perceived brilliance; balance with your design goals and budget.
