Shop Lab Grown Diamond Jewellery at Cosmos, Bangalore

Cosmos Diamonds was built in Bengaluru for people who want real diamonds and real gold without the usual compromise. Our collection of lab grown diamonds in Bangalore covers earrings, rings, necklaces, bracelets and bangles, with a kids' range and a men's range alongside. Every diamond is IGI/SGL Certified, and every piece is set in BIS Hallmarked gold, so what you see on the counter is what you take home.

Cosmos is one of the few diamond shops in Bangalore built around lab grown diamonds alone, and the HSR Layout store is where you can see the pieces up close. Diamond jewellery Bangalore shoppers want is easiest to choose when you start from the occasion and the budget, so pick a collection below and read on from there.

Why Buy Lab Grown Diamonds Instead of Mined Diamonds?

A lab grown diamond is a real diamond. It's grown in a lab and not dug out of the ground, using carbon and a controlled process that recreates what happens deep in the earth, only over a much shorter time. The origin is the main thing that changes. The stone itself, and what you can expect from it, stays the same with lab-grown diamonds Bangalore buyers pick.

  • Same material: Lab grown and mined diamonds share the same chemical makeup, crystal structure and hardness.
  • Same grading: Both are assessed on cut, colour, clarity and carat, and every Cosmos diamond is IGI/SGL Certified.
  • A lower price for the same size: Diamond price in Bangalore is the first thing most buyers ask about, and a lab grown stone usually costs less than a mined one of comparable quality, so the same budget can go towards a larger diamond.
  • No mining involved: The diamond is grown above ground, which matters to buyers who care where their jewellery comes from.
  • A way back out: With 100% Buyback, the purchase isn't a one-way decision, a reassurance buyers look for from the best diamond jewellers in Bangalore.

Find the Right Diamond Jewellery Store for Your Needs

From everyday essentials to wedding jewellery and thoughtful gifts, Cosmos offers lab grown diamond jewellery Bangalore buyers can wear for different styles, occasions and preferences, whatever diamond price in Bangalore you have in mind.

Earrings for Everyday Wear

Studs are the easiest way into diamond jewellery Bangalore buyers can wear, and they suit an office day as well as a wedding. Pick solitaire studs from our lab grown diamond earrings collections for daily wear, or a fuller pair for celebrations. Look at the carat weight of the pair and not just one stone, and check how the back fastens, since earrings that sit comfortably all day get worn more, so try them on at diamond stores in Bangalore before you decide.

Rings for Engagements

Rings run from a single solitaire for an engagement to a slim band you can wear to work. Browse the lab grown diamond rings collection, part of our lab grown diamonds Bangalore range, and decide first whether the ring is for every day or for one occasion, because that sets how high the stone should sit and how wide the band should be. Confirm your ring size before you order. Resizing a diamond setting isn't always simple.

Necklaces for weddings

A diamond pendant or necklace works with a shirt at work and a saree at a wedding, which makes it a good first piece to gift. Explore the diamond necklace collection. Think about chain length against your neckline, and about the weight of the gold, since a lighter piece is easier to wear for a full day.

Bracelets for Special Occasions

Tennis bracelets are a line of diamonds that sits as well at a dinner as under a shirt cuff. Our diamond bracelet collection includes light designs for everyday wear. Measure your wrist before choosing, and check the clasp, because a bracelet you worry about losing ends up in the box. Cosmos also has a kids' collection and a men's collection, so the same quality is there for gifting across the family.

Bangles for Weddings and Festive Celebrations

Bangles carry weddings, festivals and family functions. See the diamond bangle collection. Get the inner diameter right so it passes over the hand and still sits comfortably, and check the gold weight, since bangles are worn for long hours, so ask about it at diamond shops in Bangalore.
