Received the product. Simply wow!!!! The size and the finishing👌👌👌👌. Thank you very much for the timely delivery. Quite different from the pictures you shared. The middle solitaire size is also good enough, but due to its embossing, it looks dominant. Overall happy with the final product...🤗🤗🤗

I live in US, when I was trying to order Diamond jewellery and came across this page of Cosmos Lab grown diamonds. Initially, I had several doubts about the quality of lab grown diamonds. When I approached them, they patiently answered all my questions. I have placed an order for 2 neck pieces one from their page and another custom design which they were able to make it which looks beautiful. I had some issues in making payments but they have been very patient and supportive with the delays. I would like to mention special thanks for Ms Rafiya who helped me with the sales. She was helping me throughout the process of design to the sale. I would highly recommend the page with this experience and quality of their work.Thanks,

"I had an amazing experience with the team at Cosmos jewellery Vijayawada. I was a bit nervous about buying jewellery online, but their communication was prompt, professional, and very helpful. They went above and beyond to answer my questions and provided timely updates. It's refreshing to find such personalized service for online customers. I'll definitely be a repeat customer!

The diamond necklace and earrings I ordered were even more stunning in person than it appeared on the website. The craftsmanship is exceptional. The packaging was secure and they ensured to deliver it safely. Highly recommended!"

Deepthi Yalamanchi

Necklace

I have been purchasing jewelry from Cosmos since April 2024, and this is now my 5th purchase. Every piece I've bought has been excellent in quality and very budget-friendly.The staff is extremely friendly, patient, and helpful.For my recent purchase of a Big Haram, we worked on the item for almost 6 months, making several custom modifications to suit my requirements. Throughout this entire process, the assistance provided by Durga and Kalyani was truly excellent. They patiently answered all my queries and supported every modification with great attention and care.I truly appreciate the time and effort they invested in perfecting the piece.I am very happy with my purchases and would love to continue buying jewelry from Cosmos in the future.

Mahalakshmi Necklace

I was amazed by how beautiful the jewellery looked in person, far beyond what photos and videos could capture. The Mahalakshmi necklace was absolutely stunning, and the sparkle of the solitaires was truly eye-catching. My daughters loved their personalized name chains too. A wonderful experience with such beautifully crafted pieces and a lovely team! ❤️
