Lab diamonds from Pobjoy Diamonds

How do lab diamonds compare?

Lab grown diamonds have the same chemical composition, crystal structure and optical properties as earth created diamonds. They are not diamond simulants.

Are they more ethical?

Lab grown diamonds are less impactful to the environment than mined, earth created diamonds. They use significantly fewer resources and emit less air polution to create.

Are lab diamonds better value?


Lab grown diamonds offer fantastic value compared to mined, earth created diamonds of similar size and grade quality. Which means you will get a larger diamond for less.

All our lab grown diamonds are supplied with independent grading certification from the IGI or GIA

About Grading Certification

Every laboratory-grown diamond we supply is certified by either the International Gemological Institute (IGI) or the Gemological Institute of America (GIA), the benchmarks for laboratory-grown diamond grading.

A different report is issued for synthetic diamonds than for mined diamonds by each grading institute. IGI laboratory reports are yellow or white rather than blue.

GIA reports include a navy blue header rather than beige and white.

Laboratory-grown diamonds present an exciting opportunity for customers to get a bigger diamond at a lower price point.
