A man wants to buy an engagement ring. He has chosen the style, he has the budget, and he does not know her size.
He cannot ask. That is the entire point. He looks at sizing guides that assume he can measure a finger, printable charts that require a ring he does not have, and a note saying sizes cannot be changed after purchase.
He does not buy. The shop could have resized it afterwards at no cost, suggested borrowing a ring she rarely wears, and told him which styles are most forgiving, and none of that was anywhere.
1. Answer the surprise buyer question first
Since it is the most common situation for the highest value purchases, and almost every sizing guide is written for somebody who can measure.
2. Suggest borrowing an existing ring
The most reliable method, with guidance on which finger it is worn on and what to do with it once obtained.
3. Offer a practical fallback
An average size for the style, bought with the intention of resizing, which is how a great many rings are actually purchased.
4. State the resizing position plainly
Whether it is included, what it costs, how long it takes and whether there is a window for a free adjustment.
5. State which designs cannot be resized
Full eternity settings, certain patterns and some materials, which buyers need to know before choosing rather than afterwards.
6. Explain how much a ring can move
The number of sizes achievable in either direction, since a substantial change is different from a small adjustment.
7. Explain the effect on the ring
Whether resizing is invisible, whether it affects a pattern and whether it weakens anything, which careful buyers ask.
8. Explain the timescale
How long a resize takes, which matters enormously when a ring is needed for a specific date.
9. Explain the measuring options
Sizers sent by post, in shop measurement and what to avoid, since printed charts are unreliable and produce wrong sizes.
10. Explain the seasonal variation
That fingers change size with temperature and time of day, which is why a measurement taken once can be misleading.
11. Explain the wide band difference
That wider bands fit more tightly, which is a genuine technical point and the reason a correct measurement can still be wrong.
12. Offer to hold a size open
Where a purchase can be made and sized later, which removes the entire obstacle for a surprise buyer.
13. Handle the enquiry with discretion
Since a surprise purchase has its own privacy requirements, as in how to handle sensitive questions in your chatbot.
Explain what happens if it is still wrong
A ring resized once and still not right, and whether there is a second adjustment. Buyers with a surprise purchase are planning for two attempts and nobody tells them whether that is possible.
14. Answer the how do I find out her size question
An assistant that addresses the surprise buyer directly, suggests borrowing a ring, explains the resizing position and cost, states which designs cannot be adjusted and offers to size after purchase converts somebody who is otherwise stopped entirely. The alteration questions sit in resizing and alteration enquiries and jewellery repair and resizing questions, and a comparable fit problem in bike sizing and fit questions before buying online.
