What has changed in time is interest in its traceability, now essential for ensuring the value and origin. In fact, more and more brands are now intent on guaranteeing transparency regarding the origin of their diamonds. Like Osigem which, with its Forever Unique brand, offers a reliable and “green” proposal. Zydo has also always ensured an impeccable selection of diamond, combined with manufacturing perfection and sophisticated design. World Diamond Group unites know-how in the diamond sector, acquired over thirty years, to the reputation of international institutes that certify the quality of the raw material: a procedure it adopts with all its brands. The quality of the raw material is also fundamental for Leo Pizzo and Fope. Both companies stand out for the excellence of their Made in Italy workmanship and accurate gem selection.
