Product Description
Elevate your promise with the peerless fire and brilliance of this round cut lab grown diamond engagement ring, engineered in a distinguished trellis three-stone round setting.

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!
