4 months minimum

We only accept diamonds for a 4-month minimum time period. During this time, your stone is still ‘working’ 24\7 and we guarantee it will be presented and published everywhere we see fit in order to maximize your diamond’s chances of being sold.

4 months is too long?

We invest a lot of effort, money and time into each and every diamond we get so we will be able to provide crucial trust, which is much needed, therefore, we need to receive a decent amount of time to generate our ROI (Return on Investment). After the initial lockdown period, you can take your diamonds back if pleased and still enjoy all of our hard work by getting our digital certificate.

How much will it cost me?

Absolutely nothing! UNI’s service fee always stays the same, 3% out of the total price agreed! (e.g. you got Mazal for 100k, which is all the buyer will pay, and the vendor will get 97k (100k-3%).
