Diamond Quality for Pendants

Pendants are viewed from a distance, so you can optimize diamond quality to save money without sacrificing beauty.

Cut Quality - Still Important

• Recommendation: Excellent or Very Good cut for rounds (determines brilliance)

• Comparison: Rings need G-H (viewed up close), pendants can use H-I (viewed from distance)

Clarity - SI2 is Acceptable

• Recommendation: SI1-SI2 if eye-clean (verify with videos)
• Why: Viewed from distance, inclusions are invisible to naked eye
• Savings: SI2 saves 30-40% vs VS2, appears flawless when worn
