Frequently Asked Questions
Everything you need to know about our certified diamonds, hallmarking, and purchasing experience.
Are your diamonds natural and certified?
Yes, 100%. Every single diamond used at Rosetta Diamond Jewellery is ethically sourced and natural. All our solitaires come with internationally accredited certificates from IGI (International Gemological Institute), GIA (Gemological Institute of America), or SGL, detailing cut, color, clarity, and carat weight.
What is BIS Hallmarking?
Bureau of Indian Standards (BIS) Hallmarking is the official government purity certification for gold and silver jewellery in India. Every piece crafted in 18K and 22K gold carries the official BIS stamp, triangular logo, purity mark, and a unique 6-digit HUID code laser-engraved onto the piece.
Is high-value jewellery shipment safe and insured?
Completely. Every package leaves our Surat atelier in a tamper-evident, sealed security box and is 100% transit-insured with premium courier partners (Blue Dart Apex & Sequel Logistics). Delivery requires recipient signature and OTP verification.
What is your 30-Day Return & Lifetime Exchange Policy?
We offer a no-questions-asked 30-Day 100% Money-Back Guarantee for all standard catalogue orders. Additionally, we provide a Lifetime Exchange & Buyback policy at prevailing gold and diamond benchmark rates across all Rosetta Diamond Jewellery creations.
How should I care for and clean my fine jewellery at home?
Always apply perfumes, lotions, and hairspray before putting on your jewellery. To clean, immerse in warm water with mild chemical-free soap, gently scrub with a soft-bristled baby toothbrush, rinse in clean water, and pat dry with the provided lint-free microfibre cloth. Store each piece separately in our signature velvet pouch.
