Natural Diamonds vs Lab Diamonds: What’s the Difference?

Choosing between natural and lab-grown diamonds is one of the most common questions couples ask when shopping for engagement rings. Both types of diamonds have the same chemical composition and physical properties.

Lab diamonds popularity is skyrocketing. Based on 2025 - early 2026 data over 50% of US couples chose to go with IGI Certified Lab Diamonds. This decision makes sense for many reasons. Lab diamonds are ethically sourced and budget friendly.

For example, instead of GH color SI quality slightly under 1 carat natural diamond you can go with 4-5 carat VS clarity DEF color IGI Certified Lab Diamond.

Natural diamonds form deep inside the Earth over billions of years under extreme pressure and heat. Lab diamonds are produced using advanced technology that recreates those same conditions in a laboratory setting.

According to the Gemological Institute of America, lab-grown diamonds are created in controlled laboratory environments that replicate the natural diamond formation process (https://www.gia.edu).
