Why Clients Choose the Old Main Way

This is hands down the sparkliest ring I’ve ever seen. I get compliments from strangers constantly — it truly catches the light (and everyone’s attention). My husband surprised me with it, and he said the design process was smooth and way faster than he expected. We couldn’t be happier.

Sandy C

The original stone lacked the color and clarity I really wanted. This new one is bigger, brighter, and completely changes the look of the ring — in the best way.

I got this as a birthday gift to myself, and it’s perfect. The peridot has such a bold, beautiful glow, and the design feels so unique and special.
