What We Looked At
Our assessment of Clean Origin draws on the following public sources:

- Certification information shown on lab diamond listings
- Public product listings: shapes, carat range and setting options
- Payment and financing options shown at checkout pages

Lab-Only Selection and Certification
Because Clean Origin sells only lab-grown diamonds, its catalog is focused on lab stones and lab-diamond jewelry. According to the retailer, stones come with independent grading reports, most commonly IGI, with some GIA options. Check the report on the specific stone.
The inventory is smaller than that of the largest retailers, which can mean fewer exact matches for a very specific search.
Pricing: How to Compare
Clean Origin's prices are often competitive, particularly for buyers comparing like-for-like lab stones. Prices vary by stone and setting, so compare the same specification (carat, color, clarity, cut, certificate) at James Allen, Brilliant Earth and Blue Nile before deciding.
Policies (According to the Retailer)
- Returns: the retailer states a 100-day return window for eligible unused items. This is longer than many retailers state.
- Warranty: the retailer describes warranty coverage on its site. Read the terms for what is covered.
