Why Choose MadisonDia Lab-Grown Diamond Pendants

CERTIFICATION

IGI Certificate Sent Before Shipping

Every diamond is IGI certified. We email the certificate for your review before your pendant ships.

GOOD TO KNOW

Pendant Only, Chain Sold Separately

These listings are for the pendant itself. Pick a chain length and style separately so the finished piece is exactly how you want it.

GOLD OPTIONS

9K or 18K, Same Diamond Standard

Gold karat affects durability and price only — never diamond grading. 9K is harder and more accessible; 18K offers a deeper tone.

AFTER-SALES

1-Year Complimentary Repair

All finished pendants include one year of complimentary repair, covering prong checks and polishing.

Reference Prices by Style (1.0ct, VVS2, USD — calculated reference)

Solitaire, Round from $533 from $762
Halo, Round from $647 from $991
