Certificate of Authenticity

At Diavoria, every piece of fine jewelry is accompanied by a complimentary certificate of authenticity. We believe that trust is the foundation of luxury, and our certification process ensures you can wear your jewelry with absolute confidence in its quality, origin, and craftsmanship.

What Is a Certificate of Authenticity?

A certificate of authenticity is an official document that verifies the materials, quality, and specifications of your jewelry. It serves as a permanent record of what you have purchased and provides independent verification that your piece meets the highest industry standards. Every Diavoria purchase includes this certificate at no additional cost — it is our commitment to complete transparency.

Types of Certifications

Certified Diamond Documentation

Our diamonds are evaluated and certified by leading independent gemological laboratories. Each diamond certificate details the Four Cs — carat weight, cut grade, color grade, and clarity grade — along with precise measurements, proportions, and any distinguishing characteristics. This independent assessment ensures that the quality of your diamond has been verified by trained gemologists using standardized criteria recognized worldwide.

Gemstone Certification

Colored gemstones such as sapphires, rubies, emeralds, and other precious stones receive detailed documentation that includes the stone type, carat weight, dimensions, color description, clarity assessment, and any treatments or enhancements. Where applicable, origin information is provided to give you a complete picture of your gemstone's journey from source to setting.

Metal Purity Verification

Every piece of Diavoria jewelry is crafted from genuine precious metals. Our certificates confirm the metal type and purity — whether 14K or 18K gold, platinum, or sterling silver. The hallmark stamp on each piece corresponds to the documented purity, providing an additional layer of verification that the metal content meets or exceeds industry standards.

What Your Certificate Includes

Each Diavoria certificate of authenticity contains the following information:

• Product identification — item name, SKU, and unique certificate number
• Stone specifications — type, carat weight, cut, color, clarity, and dimensions
• Metal details — type, purity (karat or fineness), and weight
• Grading summary — quality grades assigned by independent gemological assessment
• Origin and sourcing — information on where materials were sourced, where available
• Treatment disclosure — any treatments or enhancements applied to gemstones
• Date of certification — when the piece was evaluated and documented

Recognized Certification Bodies

Our diamonds and gemstones are evaluated and certified by the world's most respected independent gemological laboratories. These organizations set the global standard for grading accuracy and consumer protection:

IGI (International Gemological Institute)

The IGI is the world's largest independent gemological laboratory, specializing in the certification of both natural and ethically sourced diamonds. Every IGI report includes detailed assessments of the 4Cs (Cut, Color, Clarity, and Carat Weight), along with a unique identification number and laser inscription. Diavoria's diamond jewelry comes with IGI certification to ensure verified quality and authenticity.

GIA (Gemological Institute of America)

The GIA is the gold standard in diamond grading, having created the universally recognized 4Cs grading system. GIA reports are trusted worldwide for their accuracy and impartiality. GIA-certified stones in our collection represent the highest level of third-party verification available in the jewelry industry.

AGS (American Gem Society)

AGS is known for its advanced cut-grading methodology, using a 0-10 scale where 0 represents the ideal. AGS certification is particularly valued for its rigorous assessment of light performance and proportions, making it a trusted standard for premium diamond jewelry.

What Your Certificate Includes

Each Diavoria certificate of authenticity documents the following verified details about your jewelry:

• Gemstone specifications — type, carat weight, cut, color, and clarity as graded by recognized laboratories
• Metal composition — verified purity (e.g., .925 Sterling Silver, 14K Gold, 18K Gold, Platinum)
• Unique product identifier — your piece's individual SKU and serial reference
• Origin and sourcing — confirmation of ethical sourcing and responsible supply chain practices
• Warranty coverage — details of your lifetime warranty protection

How to Verify Authenticity

We encourage every customer to verify their jewelry independently. Here is how:

1. Review your certificate — Compare the details on your certificate with the physical piece. Check the hallmark stamp, stone characteristics, and metal weight.
2. Laboratory verification — If your piece includes a certificate from an independent gemological laboratory, you can verify it directly through the laboratory's website using the certificate number provided.
3. Professional appraisal — Take your jewelry and certificate to any certified independent appraiser. The documented specifications should match their assessment.
4. Contact our team — If you have any questions about your certificate or wish to request additional documentation, our jewelry specialists are available to assist you.

Why Certification Matters

Jewelry is both a personal treasure and a significant investment. Proper certification protects you in several important ways:

• Confidence in quality — You know exactly what you are purchasing, verified by independent experts
• Insurance purposes — Certificates provide the documentation that insurers require to properly cover your jewelry
• Resale value — Certified pieces retain their value better and are easier to appraise accurately
• Peace of mind — Complete transparency means no surprises about what you own
• Ethical assurance — Documentation of sourcing supports responsible and ethical practices in the jewelry industry
