Our Natural Diamond Guarantee

At Zina Fine Jewelry, we believe that trust begins with authenticity.

Every diamond in our jewelry is a 100% genuine, natural, earth-mined diamond. To protect the integrity of every piece we create, we follow a rigorous two-step diamond verification process.

Step 1 – Incoming Diamond Verification

Every parcel of melee diamonds is professionally tested upon arrival from our suppliers to verify that each diamond is natural before it enters production.

Step 2 – Final Jewelry Verification

Once your jewelry has been handcrafted and every diamond has been set, the completed piece is tested a second time to ensure that no laboratory-grown diamonds have been inadvertently mixed into the finished jewelry.

This additional level of quality control allows us to confidently guarantee that every diamond in your jewelry is 100% natural, earth-mined, and never laboratory-grown.
