What is the Tanishq Certificate of Authenticity for Natural Diamonds? Are you of the view that the price of your diamond jewellery product alone confirms its authenticity? Let’s break the myth because a higher price tag may not always be equivalent to the real deal! Certification must be the primary consideration in determining whether or not your jewellery product is authentic. Not all diamonds are natural; cheap lab-grown alternatives have infiltrated the scene to a certain degree. The lab-grown diamonds appear similar to the natural ones, and only specialised tools or certified proofs can vouch for gem authenticity. The Tanishq Certificate of Authenticity guarantees the quality, purity and genuineness of fine jewellery. Certificates extended by us, at Mia by Tanishq, guarantee that our diamonds are 100% natural and that the gold is accurately hallmarked. Read this blog and discover more about the Tanishq diamond certification standards!

Why is Diamond Jewellery Certification Necessary in India? Diamond certification in India verifies the 4Cs, including cut, clarity, colour, and carat for the precious gemstones. It also confirms the purity degree of the metal base. This certification also includes a one-year warranty that protects against potential manufacturing defects. Jewellery certification is crucial in India because: * Authenticity influences the price tag, the product’s value in the long term and its emotional appeal. * The natural diamonds are of a rare stature and have a unique story of formation spanning over billions of years. Such factors contribute to its enduring worth. * If you’re making purchases for meaningful gifting, you’d want to make sure your sentiment is conveyed with truly one-of-a-kind precious picks. * You are entitled to the real deal when you pay the price for it. The Tanishq Certificate of Authenticity takes Mia's commitment to transparency a step further by ensuring the following: * Diamonds are accurately graded in loose form before being set into the gold base. This ensures the unbiased analysis of the cut, colour, clarity and carat details. * A 100% caratage assurance up to 3 decimal points is presented. Rest assured of zero deviation from the quoted weight. * The gemstones featured in a specific jewellery piece belong to a consistent colour/clarity level, as would be certified in the document. * Net or gross weight is billed precisely. The stone weight is deducted and documented clearly. Why is Knowledge About the Diamond’s Origin Significant? Diamonds should ideally come with complete disclosure about whether they are natural or lab-grown. Ethical sourcing guidelines like the ones surrounding the Kimberley Process guarantee that natural diamonds are: * Conflict-free * Responsibly mined This builds confidence in the journey of the gems from deep within the Earth to their final glistening state. In order to identify the original diamond source, look out for explicit written confirmation. Proper jewellery authenticity certificates from recognised laboratories must ensure that the diamond is natural. The Tanishq heritage itself offers a quality guarantee that is globally trusted. With the Tanishq seal backing our products at Mia, you’ve got nothing to worry about! Tanishq’s certification of authenticity is issued after the diamonds undergo a rigorous backend system of: * Authenticity checks * Grading * Quality verification What Role Does Transparency Play in the Diamond Jewellery Market? As lab-grown diamonds are also being used in jewellery design, transparency around the diamonds' origin has become all the more important to determine. Open disclosure, mindful sourcing, and dependable certification shall help buyers make informed decisions without the additional ambiguity. Here, at Mia by Tanishq, high-tech systems back the long-standing trust. The comprehensive billing process prioritises clarity, with gold and diamonds separately accounted for. There is a transparent declaration about the diamonds being 100% natural. You can visit the in-store diamond expertise centres to uncover the science behind the stone that calls your name! How are Natural Diamonds Identified? The buyer’s confidence is built upon through certification from recognised institutes. It’s one of the simplest yet most reliable ways to check for real diamond authenticity. These certificates mention the diamond’s origin, unique characteristics and grading category. They serve as an additional layer of protection against getting duped. Mia by Tanishq diamonds are superior as they confidently hand over the reins to customers. Our customers can then further go into the nitty-gritty of the diamond's history and truly understand the sparkle that soothes their soul. Here are more ways in which natural diamonds can be identified: 1. Tracing Patterns of Inclusions and Growth Natural diamonds display true-to-nature, irregular and organically shaped inclusions that are not perfected by lab equipment. The key here is not ‘perfection’ but rarity and uniqueness. The growth strain is also sculpted over billions of years, typically only visible under 10x magnification. The internal diamond features appear starkly different, with more uniform growth patterns as observed in lab-grown stones. These traceable patterns are pointers taken into consideration by experts when they have to identify a real, natural diamond. 2. Accessing Advanced Testing Methods Professional gemmologists have access to high-tech devices that allow testing in the form of spectroscopy and fluorescence analysis. The equipment and knowledge help them differentiate natural diamonds from lab-grown alternatives. At the Tanishq Diamond Expertise Centre, you shall be empowered with access to various De Beers technologies like the SynthDetect and the Caratmeter. Thus, confirm whether a gem is natural or lab-grown yourself, with nobody trying to sell you ‘honesty’. You simply figure it out on your own accord. Further, the LightScope will verify a specific diamond's light performance, enhancing your grasp of the intensity of sparkle you're choosing for life! Thus, get lab-level answers to questions about your chosen diamond muses before taking them home. 3. Associating with Trusted Brands When you’re shopping for diamond jewellery, it's not the time to take chances! They are big investments, and you've got to make sure that your bucks are well-spent for value, not in vain. Don't rely on at-home tests post buys; simply choose the brand that has proven its trustworthy stature through decades.
