Product Description
Product Description
Step into forever with the enchanting beauty of this marquise cut lab grown diamond engagement ring, refined by its architectural vintage inspired heirloom marquise setting. Meticulously handcrafted for an everlasting commitment, this piece radiates brilliant fire, perfectly elevated by its sleek setting.
The focal point is an extraordinary marquise cut lab grown diamond, precisely faceted to maximize dispersion and brilliance. Secured firmly by vintage-style double claw or tab prongs integrated into an open ornate milgrain engraved gallery, every angle invites radiant light return. With a comfortable cathedral profile with intricate filigree gallery and a silky carved milgrain diamond pavé band (1.65mm), it offers a seamless blend of durability and luxury. Intricate milgrain bordering and vintage hand-carved filigree arches bring timeless antique romance and heirloom craftsmanship.

The Ring of My Dreams ✨
I came to Northfire Jewelry knowing I wanted a lab grown diamond but had no idea where to start. Victor walked me through every option patiently. The ring we designed together is absolutely stunning - the diamond has so much brilliance and fire. I get compliments every single day. Worth every penny.

Incredible Quality, Half the Price
We chose a lab grown diamond from Northfire Jewelry for my engagement ring and could not be happier. The stone is IGI certified, beautifully cut, and looks identical to any mined diamond - except we saved thousands. The custom ring was ready in under 3 weeks and arrived perfectly packaged. Highly recommend to anyone considering lab grown.

Ethical, Beautiful, and Stress-Free
Buying an engagement ring felt overwhelming until I found Northfire Jewelry. The entire process was transparent - I knew exactly what I was getting and why it was priced the way it was. The lab grown diamond is flawless to the eye and the craftsmanship on the setting is exceptional. I proposed last month and she said yes. Thank you Northfire!
