The 4Cs and price impact
Cut
Cut quality strongly affects brilliance. Excellent/Ideal cuts often command a premium for better light return.
Color
Higher color grades price higher, but many buyers can balance cost and appearance by moving slightly down the scale.
Clarity
Price jumps as inclusions become less visible. Eye-clean ranges can offer strong value in many shapes.
Carat
Carat has the largest non-linear impact on price, especially around popular size thresholds.
