Certifications at Diava

At Diava Diamonds, we believe in complete transparency and trust when it comes to your jewellery purchase. We understand that buying fine jewellery is an important investment, and certifications play a key role in ensuring the quality and authenticity of your piece. Below, we explain the certifications provided with our Gold, Lab-Grown Diamonds, and Natural Diamonds so you can make informed decisions with confidence.

Gold Certification

At Diava Diamonds, all our gold jewellery is certified with the BIS Hallmark to guarantee purity and quality. BIS (Bureau of Indian Standards) is the national standards organization of India, and its hallmark is a globally recognized certification for gold quality.

What the BIS Hallmark includes:

  • Purity in Karats: The hallmark will clearly state whether the gold used is 14K, 18K, or 22K.
  • BIS Logo: The logo of the Bureau of Indian Standards is engraved on all our gold jewellery.
  • Jeweller’s Identification Mark: Each piece carries a unique mark to identify the jeweller.

You can verify the hallmark of your gold jewellery using the BIS Care App. Download the app for a seamless way to check your hallmark authenticity: BIS Apps.

Lab-Grown Diamond Certification

Lab-grown diamonds are identical to natural diamonds in terms of chemical, physical, and optical properties, and they are graded and certified using the same rigorous standards. At Diava, all lab-grown diamonds 1 carat and above come with an IGI (International Gemological Institute) Certificate.

What the IGI Certificate includes:

  • Carat Weight: The exact weight of the diamond.
  • Colour and Clarity Grading: IGI provides a precise grade for color and clarity, following the same standards as natural diamonds.
  • Cut Quality: Evaluation of the diamond’s cut, which affects its brilliance and sparkle.
  • Polish and Symmetry: These factors determine how well the diamond has been shaped and finished, impacting its overall appearance.
  • Fluorescence: This refers to the diamond’s reaction to UV light, and the certificate will indicate whether the diamond has any fluorescence.
  • Unique Laser Inscription: Each certified lab-grown diamond carries a unique laser inscription that matches the IGI certificate for easy identification.

Natural Diamond Certification

Natural diamonds are rare and timeless, and their certification is crucial for verifying their authenticity and value. At Diava, we provide certification for all natural diamonds over 1 carat from either IGI (International Gemological Institute) or GIA (Gemological Institute of America)—the two leading diamond grading organizations in the world.

What the IGI and GIA Certificates include:

  • Carat Weight: The precise weight of the diamond.
  • Color, Clarity, and Cut Grading: Both IGI and GIA provide a detailed assessment of the diamond's color, clarity, and cut. These grades are critical in determining the diamond's overall value.
  • Polish and Symmetry: Evaluation of the diamond’s surface finish (polish) and overall proportions (symmetry).
  • Fluorescence: Assessment of any natural fluorescence under UV light.
  • Unique Laser Inscription: Each diamond is inscribed with a unique ID number corresponding to its certificate.
