Are ONYA's lab-grown diamonds real diamonds?

Yes, lab-grown diamonds are 100% real diamonds — chemically, physically, and optically identical to mined diamonds. ONYA's diamonds are IGI-certified with VVS-EF clarity, so you get the same brilliance and quality at just 20% of the price of a natural diamond.

What is the price difference between ONYA's lab-grown diamonds and natural diamonds?

ONYA's lab-grown diamond jewellery is priced at approximately 20% of what you'd pay for equivalent natural diamond pieces, making luxury jewellery accessible without compromising on quality. All pieces are set in hallmarked gold and IGI-certified, ensuring complete transparency in value.

Does ONYA offer a buyback or exchange policy?

Yes! ONYA offers a 100% lifetime exchange and an 80% buyback guarantee on all jewellery purchases. This makes your investment in lab-grown diamond jewellery secure and flexible for the long term.

Can I visit an ONYA store in Bangalore to see the jewellery before buying?

Absolutely! ONYA has multiple stores across Bangalore, including locations in Jayanagar, HSR Layout, Indiranagar, and Whitefield Main Road. You're welcome to visit, try on pieces, and speak with our jewellery experts in person.

Can I customise my jewellery — for example, a mangalsutra or engagement ring?

Yes, every ONYA piece is fully customisable — you can choose your diamond size, gold purity, design, and setting to match your preferences or occasion. Simply visit any of our Bangalore stores or contact us online to begin your customisation.

How is ONYA different from other lab-grown diamond brands like Ethera or Limelight Diamonds?

ONYA stands out with IGI-certified VVS-EF clarity diamonds, hallmarked gold settings, an 80% buyback guarantee, and physical stores across Bangalore for a trusted in-person experience. While other brands may offer lab-grown diamonds online, ONYA combines certified quality, competitive pricing, and local accessibility all in one place.

Does ONYA offer free shipping, and how long does delivery take?

Yes, ONYA offers free pan-India shipping on all orders, including deliveries across Bangalore. Delivery timelines vary by product and customisation, so our team will confirm the exact timeline at the time of purchase.
