Engagement Rings Made to Order in Los Angeles

2 carat diamond engagement rings, made to order in our Los Angeles atelier. Every setting is crafted in solid gold or platinum and paired with a GIA or IGI certified diamond scored by ROSI™, gemological intelligence built by our gemologists. One fair price, a 40 day return window, complimentary 60 day resizing, and a lifetime warranty on every ring.

Good to Know

Engagement Ring Questions

Is the price for the complete ring or the setting?
Made to order settings are priced without the center diamond. You choose that separately, with our gemologists and ROSI™ guiding you to the strongest stone for your budget. Select Collection rings are complete, setting and center diamond together, at one price.
How long until my ring arrives?
Every made to order ring is crafted in our Los Angeles atelier in 8 to 12 business days, then shipped fully insured with a signature required at delivery.
Can I see a setting with a different diamond shape?
Most settings accommodate several center shapes. Open any ring and choose your shape in the configurator, or speak with our gemologist and we will confirm what works for the design you love.
What if it isn't right?
You have a 40 day return window on pieces that are not engraved or custom designed, complimentary resizing for 60 days, and a lifetime warranty on every ring.
