🛒 Marquise Buying Tips
1. Verify Perfect Symmetry
Both pointed ends must be identical. Choose Excellent or Very Good symmetry.
2. Check for Bow-Tie
Request HD video. Accept minimal bow-tie, avoid strong bow-tie.
3. Protect Both Points
Use V-prongs or claw prongs on BOTH pointed ends. Essential for durability.
