The Exchange Promise Is Not the Same as the Exchange Policy
Most buyers in Bangalore who ask about lifetime exchange stop at the headline number — 100% exchange value — and assume the details will sort themselves out later. They tend not to, at least not without some friction. The gap between what a policy promises and what it actually covers in practice is where most disputes originate, and it is entirely avoidable if you understand the terms before you buy.
This article breaks down exactly what a lifetime exchange policy covers for lab-grown diamond earrings — using ONYA’s published policy as the reference standard — including the conditions that must be met, the documents you need to hold on to, and the practical steps to make a claim. The same framework applies whether you bought solitaire studs, hoop earrings, or drop earrings.
One clarification worth making upfront: exchange and buyback are two different mechanisms. Exchange means you return an existing piece and receive credit toward a new purchase, typically at 100% of the original value. Buyback means the brand repurchases the piece from you in cash, usually at a lower percentage — ONYA’s buyback rate sits at 80% on the diamond component. This article focuses on the exchange side, though the documentation requirements for both overlap significantly.
What “100% Lifetime Exchange” Actually Means
ONYA’s exchange policy offers 100% lifetime exchange on its jewellery — meaning if you bring back a pair of diamond earrings you purchased from them, you receive the full original purchase value as credit toward any other piece in their collection. There is no time window on this. It does not expire after two years or five years. The “lifetime” designation is genuine, not a marketing qualifier with a hidden expiry clause buried in the fine print.
But 100% exchange does not mean the transaction is frictionless or unconditional. The credit applies to the value of the piece at the time of original purchase, not to any appreciation in gold or diamond prices since then. If gold rates have risen significantly in the years since you bought your earrings, the exchange credit reflects what you paid, not what a comparable piece costs today. You would pay the difference on the new order.
This is standard practice across the category. Most reputable lab-grown diamond brands in India — including those with 50+ physical stores — operate exchange policies on the same basis: original purchase price as the exchange reference point, with the customer covering any upward difference on the new piece. What distinguishes stronger policies is the absence of arbitrary deductions, the inclusion of custom designs in the exchange scope, and the clarity of the written terms. ONYA’s policy covers custom-designed pieces as well as catalogue items, which matters because a significant share of their earring sales involve bespoke settings.
The Documents You Cannot Afford to Lose
Every exchange claim — regardless of brand — requires two core documents: the original purchase invoice and the IGI certificate that accompanied the piece. These are not interchangeable, and neither one alone is sufficient.
The IGI certificate is the independent third-party record of your diamond’s specifications — carat weight, cut, colour, and clarity grade. For ONYA earrings, all diamonds are graded VVS-EF clarity, and the certificate confirms this. The certificate number is laser-inscribed on the girdle of the stone, which means the physical diamond and the paper document can be matched against each other. If a stone has been swapped or damaged in a way that alters its graded characteristics, the mismatch becomes immediately apparent during the exchange assessment.
The original invoice is the legal proof of transaction. It records what you paid, when you paid it, and the specific piece you purchased. Without it, the exchange team has no documented basis for calculating the 100% credit. Some buyers assume the brand can look up their purchase history from an account or phone number — and sometimes they can — but the invoice remains the cleanest and most unambiguous record, particularly for purchases made years earlier.
A practical note: store these two documents separately from the jewellery itself. If the earrings are lost or stolen, you want the paperwork intact. A scanned digital copy stored in cloud storage or emailed to yourself is a reasonable backup, though the original physical documents are preferred for in-person exchange claims.
Other documentation that helps but is not always mandatory: the original packaging and jewellery box, any warranty card issued at the time of purchase, and photographs of the piece in its original condition. The more complete your documentation, the faster the exchange process moves.
Conditions the Piece Must Meet
The exchange credit applies to the piece, not just the diamonds. This means the physical condition of the earrings at the time of return matters. A quality check is standard — the brand assesses whether the piece has been subjected to damage beyond normal wear, whether stones are missing, and whether any alterations have been made by a third-party jeweller.
Normal wear is expected and accepted. Earrings worn daily for three years will show minor surface marks, and this does not disqualify an exchange. What tends to complicate claims is structural damage — a broken clasp that was repaired elsewhere using incompatible materials, a stone that fell out and was replaced with a non-original diamond, or a setting that was resized or altered in a way that compromised the original metalwork.
This is one reason ONYA offers free repair services for the first year after purchase, along with lifetime cleaning and polishing. Using the brand’s own service network for maintenance keeps the piece within its documented history and avoids the complications that arise when third-party repairs are involved.
For earrings specifically — studs, hoops, and drops — the most common condition issues that surface during exchange assessments involve post damage on studs (bent or broken earring posts are often repaired externally) and clasp mechanisms on hoop or drop styles. If you notice any structural issue with your earrings, getting it addressed by the original brand rather than a local repair shop is the cleaner path.
Customisation adds a layer of nuance. ONYA does extend exchange coverage to custom designs, but the exchange credit still reflects the original purchase price. A highly personalised setting that would cost significantly more to reproduce today does not increase the exchange value — the credit remains anchored to what was paid at the time of purchase.
How to Actually Make the Exchange Claim
The process is more straightforward than most buyers expect, provided the documentation is in order.
For Bangalore customers, ONYA operates stores in Jayanagar, Whitefield, Indiranagar, Neeladri, and HSR Layout. An in-store visit is the most direct route for an exchange claim — you bring the earrings, the IGI certificate, and the original invoice, and the team conducts the quality check on the spot. The exchange credit is then applied toward your new selection. If the new piece costs more than the credit, you pay the difference. If it costs less, most brands do not issue a cash refund for the remainder — the credit is typically non-transferable and applies only to the new purchase.
For customers who purchased online or are not near a physical store, ONYA’s shipping is free and insured across India, and the exchange process can be initiated remotely. The standard approach is to contact the brand via WhatsApp or email, confirm the exchange intent, ship the piece using the brand’s logistics arrangement (using reputed carriers like Sequel or BVL), and await the quality assessment before the credit is confirmed.
Timelines vary depending on whether the new piece requires customisation. A catalogue item can typically be dispatched within a few days of the exchange being confirmed. A custom order — say, a different earring style in a specific gold karat — follows the standard production timeline of 15 to 20 days from order confirmation.
One thing worth confirming before initiating any exchange: the specific piece you want as the replacement. Walking in with a clear idea of what you are moving toward makes the transaction faster and avoids the situation where exchange credit sits in a kind of administrative limbo while you decide.
Exchange vs. Buyback: Choosing the Right Option
If your goal is to upgrade to a different style of diamond earrings — or to move from earrings to a ring or pendant — the lifetime exchange at 100% is the stronger financial outcome. You retain the full original value as purchasing credit and direct it toward whatever piece you want next.
If your goal is liquidity — you want cash rather than store credit — the buyback route applies, with ONYA offering 80% of the diamond value in that scenario. The 80% figure applies to the diamond component; the gold is assessed separately at prevailing market rates. This distinction matters for earrings with significant gold weight, where the metal component can represent a meaningful share of the total piece value.
For most Bangalore buyers who are thinking about upgrading their jewellery over time, the exchange route is the one that makes more practical sense. The 100% credit means no value is lost in the transaction, and the new piece can be anything in the catalogue — rings, a mangalsutra, a pendant, or another pair of earrings entirely. The only requirement is that the exchange credit is used within a single transaction toward a new ONYA piece.
The broader point is that a well-structured lifetime exchange policy changes how you should think about the upfront cost of lab-grown diamond jewellery. A piece that retains 100% of its value as exchange credit is not a sunk cost — it is a redeployable asset. That framing is especially relevant for earrings, which tend to be the category where buyers are most likely to want to evolve their style over time.
