Learn more about the vendor’s path





Diamond trading has been stagnant for the past century without any significant shift to online trade. Online billboards and direct retail portals have become common only in the last decade. The benefits of the collaborative economy and advanced marketplace technologies had only recently been implemented.

UNI was founded and designed by diamond trading veterans for usage of all diamond trading parties. UNI founders have decades of experience within the diamond trading industry being a part of a three generations diamond trading tradition. UNI brings this traditional trading experience into the new digital trading arena facilitating new digital tools with traditional trading methodologies.

Our unique marketing position permits UNI to offer exceptional and incomparable transparency. All diamonds over UNI are physically kept with Malca-Amit and with UNI’s flexible vendor and buyer negotiation interfaces, we enable both parties to seamlessly reach a closing price.
