Every lab-grown diamond brand in India today advertises some version of the same reassurance: "lifetime exchange," "assured value," "upgrade anytime." The words sound interchangeable. They are not. The difference between an exchange policy and a cash buyback policy can be worth lakhs of rupees over a lifetime of jewellery ownership and it is the single most revealing question you can ask any jeweller before buying.
Exchange vs BuyBack: the difference in one minute.
Lifetime exchange means the brand will accept your old piece as part-payment but only toward a new purchase from the same brand, on the brand's valuation terms. Your money stays locked inside their store forever. It is a loyalty mechanism dressed as a guarantee.
Cash buyback means the jeweller will hand you money for your jewellery, at a percentage stated in writing, with no obligation to buy anything. Your jewellery remains what Indian families have always understood it to be: an asset you can liquidate in an emergency, a wedding, a business opportunity.
Exchange is convenient. Buyback is protection. A trustworthy jeweller should offer both.
Why most new brands avoid cash buyback.
It is not villainy, it is business models. Venture-funded jewellery startups are built for growth: revenue, store counts, repeat purchases. An exchange-only policy guarantees the returned customer buys again; a cash buyback is a real liability on their books. Traditional jewellers, by contrast, have run buyback for generations because their model is built on multi-decade family relationships, where the willingness to give money back is precisely what earns the next generation's business.
So when you evaluate any brand, startup: corporate or family jeweller - the buyback question instantly reveals whose interest the policy really serves.

The fine print that decides everything.
Whichever brand you consider, read the policy document, not the ad and check these five clauses:
1. Percentage, in writing. "Assured buyback" without a number is not a promise. Ask: what exact percentage of the diamond value, and what percentage of the gold value?
2. Cash or credit? Some policies quietly pay "buyback" as store credit. Credit is exchange wearing a different name.
3. Gold valued separately, at the day's rate. The gold in your jewellery has an open market price. A fair policy values it at the prevailing rate on the day you return it which is why we publish the daily gold rate openly.
4. Certificate requirements. Policies typically require the original certificate and invoice. Keep both safe; they are your jewellery's passport.
5. Who honours it, and where? A policy honoured only through an app or courier process is weaker than one you can walk into a showroom and invoke, face to face.
Where Goenka Jewellers stands.
Our policy is printed on our website banner, not buried in fine print: buyback of 80% cash on diamonds and 100% cash on gold - alongside a 100% exchange offer for the day you would rather upgrade than encash, plus a lifetime warranty on every piece. Every diamond is IGI certified, every gold component HUID-hallmarked and billed at the transparent daily rate, so the valuation at buyback time is arithmetic, not negotiation.
We can offer this because we are not spending investor money to buy market share, we are a jewellery house whose only growth engine is that your family comes back, and sends others. That is what Crafting Legacy Forever commits us to.
Frequently asked questions
Is 80% cash buyback on lab-grown diamonds unusual in India?
Written cash buyback of any kind is rare in this category - most brands offer exchange-led policies. Always compare the written terms of any brand you shortlist.
Does the buyback apply to old purchases too?
It applies to jewellery purchased from Goenka Jewellers with its certificate and invoice. Visit us with your piece and documents and we will value it on the spot.
What if I bought a lab-grown diamond elsewhere?
Bring it in, while our written buyback covers our own jewellery, we are happy to evaluate outside pieces and advise you honestly on your options, including exchange toward a Goenka piece.
Buy with an exit, not just an entry: explore our IGI-certified collection or book an appointment to see the buyback terms in writing before you spend a rupee.
