Every Vantari timepiece and high jewelry creation is accompanied by a certificate of authenticity, verifying the origin, quality, and specifications of the materials used. This certificate serves as formal documentation that your piece is genuine, ethically sourced, and handcrafted to the highest standards of excellence.

All diamonds and gemstones used in our collections are independently authenticated and graded by recognized gemological experts. Each certificate provides detailed information on cut, carat, clarity, color, and any special characteristics, offering full transparency and confidence in your purchase.

Our precious metals, including platinum and gold, are also verified for purity and compliance with international standards. The certificate issued with your item confirms that it meets our strict criteria for ethical sourcing and material quality.

We recommend keeping your certificate in a safe place, as it may be requested for insurance purposes, resale, or servicing in the future. Should you misplace your original document, please contact us to discuss options for a reissue.

At Vantari, authenticity is not only guaranteed — it is a core part of our promise to you.
