How are Feefo reviews collected?

We independently collect feedback on behalf of the businesses that work with us. Our platform only reaches out to verified buyers, so you can be sure you’re reading reviews from real customers.

Who can leave a Feefo review?

Only customers with proof of purchase can leave a Feefo review. We ensure this by reaching out to buyers straight after their transaction.

How do we verify reviews?

We verify that reviews are from genuine customers by matching them to a sale or transaction. People are only invited to leave a review after purchasing from the business.

How do we deal with fake reviews?

Feefo prevents people from leaving fake reviews because we only invite verified buyers to give feedback.

Set of 11 diamond colour-grading stones by Gemoro

ratings

over the past year

Details The only way to colour-grade diamonds is to match the colours against carefully-graded samples. Here are 11 carefully colour-graded stones, 1.00ct each, colours D to N. This set is unique in that it has 11 stones, and also because it has a built-in UV light (with a USB-rechargeable battery). Please note, these are colour-grading stones for diamonds, they are not diamonds (they are Cz).
