Every protection a buyer has — the seller's written description, the laboratory report, the platform's guarantee — comes down to one thing: the ability to return the article if it is not what it was sold as. That ability has a time limit, and the time limit is what makes or breaks it. A return window that closes before an independent laboratory can examine the article is a return window in name only.
How long testing takes
Postage to the laboratory. One to four days domestically, depending on service.
Examination and report. Most laboratories examine a single article within a day or two of receipt. Batches and unusual articles take longer.
Return postage. Another one to four days.
Deciding and initiating the return. A day.
Add margins for weekends, holidays and the seller's handling time, and the practical minimum is fourteen days from delivery. Longer is better; thirty days is comfortable. Anything under ten days is unlikely to allow the round trip.
The sequence
Day of arrival. Photograph everything before unpacking fully — the parcel, the packaging, the article, the certificate, the invoice. Weigh and measure the article and compare with the description and any report. Matching the report to the article in your hand.
Within a day or two. If the value justifies it, send the article to a laboratory unconnected to the seller, by tracked post, with a note of what was claimed and what you want examined. Keep the certificate and invoice with you.
On receiving the report. Compare its findings with the seller's written description. If they agree, the purchase is confirmed. If they differ, initiate the return immediately, with the report, the invoice and the photographs.
Before the window closes. Make sure the return is registered with the seller or platform in writing, even if the article is still in transit back. A return initiated inside the window and completed just after is usually honoured; one initiated after the window is not.
When there is no return window
Before buying. A seller who offers no returns, or a window too short to test, is offering an unprotected purchase. For an inexpensive article that may be acceptable. For anything significant, either negotiate a testing period, arrange to test before completing the purchase (some sellers will send an article to a laboratory on deposit), or do not buy.
After buying. Test anyway. A report that contradicts the description is evidence for a dispute through the payment provider, the platform or consumer protection channels, even without a formal return right. The written description on the invoice is what the report is compared against, which is why obtaining it matters. Questions to ask a seller before you pay.
Exclusions to watch for
"No returns on religious items", "energised items are non-returnable", "custom-cut stones are final sale", "returns only for damage in transit". Each of these removes the protection that matters. A policy that returns damaged goods but not mis-described ones has understood the problem exactly and declined to solve it. Energised and siddha claims versus testing.
The laboratory's part
A laboratory can help by turning reports around promptly, by stating findings in terms that map to the seller's claims (natural/synthetic, treated/untreated, natural faces/artificial faces), and by providing a report that verifies online so that the seller can confirm it. It cannot compel a refund; the report is the evidence, and the return policy is the mechanism.
Frequently asked questions
Is fourteen days really enough?
Usually, with prompt action. Thirty days removes the pressure. Less than ten is a gamble on postal speed.
Should I test every purchase?
Test in proportion to the price and the rarity of the claim. A cheap five-mukhi mala does not need a report; a sapphire or a fourteen-mukhi bead does.
What if the seller says testing voids the return?
Non-destructive testing changes nothing about the article. A seller who refuses returns on tested articles is refusing returns on articles that were checked, which is the point.
Can the seller dispute the laboratory's finding?
They can, and may offer their own certificate in reply. An independent report with named tests and measured values carries more weight than a seller's certificate, and a second independent opinion settles most disputes.
Does a platform's guarantee replace this?
Platform guarantees vary in what they cover and require evidence. A laboratory report is the evidence. Use both.
