Is the jewellery real and certified?
We only use BIS hallmarked 18kt gold which is the most durable for diamond jewellery and IGI/EGL certified sustainable diamonds.
BIS hallmark is a sole agency verified by the Government of India, which authenticates the quality and karat of gold. All cosmos jewellery comes with a laser engraving of the Hallmark code to authenticate the karat of gold and certificate for diamond authenticity, This can help you resell your piece in the future, if needed.

All of our diamonds are graded colourless-near colourless (E-F) and are graded (VVS-VS for clarity. Each certificate contains detailed information of the diamond’s cut, carat, color and clarity. we also make beautiful jewellery with color diamonds like pink, blue, yellow.

What are sustainable diamonds?
The truth of mined diamonds is no more a mystery. With history of slavery, wastage of water, destruction of the land and habitat caused with Mining.So we really wanted to make a difference.With technology, we can produce a real diamond under controlled conditions inside a laboratory just like it happens inside the earth crust and impact of doing so is huge.
it is sustainable to grow diamonds with abundantly available carbon and renewable energy. Growing diamonds is certainly energy intensive; however, the impact on the earth to grow diamonds is a fraction of the impact of diamond mining.
Mining 1 carat of diamond displaces 10,000 sqft land, uses hundreds of gallons of water might result in displacing natural habitat, deforestation and impacts Co2 emissions. all of which can be avoided by choosing sustainable diamonds.
Is there any other difference to tell apart mined and lab-grown diamonds other than origin?
Nope, there simply isnt. A jeweller under a microscope cannot tell the difference nor a simple diamond tester which tests chemical composition because they’re both diamonds! Our lab diamonds have the exact same chemical and optical properties as mined diamonds.In most cases, sustainable diamonds are certified Type 2a, which is the purest form of diamonds. Only 2% of all mined diamonds are of that quality. So sustainable diamonds are known to shine brighter with lesser impurities!
Can you customise jewellery?

1. Setting the stage
The Chemical Vapor Deposition (CVD) diamond growth process begins with our high-quality Type IIA ‘seeds,’ or thin slices of diamonds. Once placed inside of our proprietary growth chambers, we introduce a tailored mixture of carbon-rich gases, heating them to create a greenhouse-like environment mirroring natural growth conditions.Through the art and magic of science, of discovery and evolution – over time, pure carbon organically bonds with each seed, atom by atom, resulting in the growth of new crystalline structure.
3. Diamond in the rough
Once the rough diamonds have reached their optimal height, our team of scientists remove them from the growth chamber, proceed with quality assurance testing, and shepherd the best-of-the-best through to our finishing stages.
Each Cosmos diamond is then planned, cut and polished by our expert artisans to amplify its brilliance. Finally, it is graded and certified by the world's leading independent laboratories, responsible for assessing the top mined gemstones in the world.
