How charity shops can use WhatsApp photos to check jewellery before selling it cheaply.

The single highest-leverage operational change a charity shop can make is a WhatsApp photo loop with a precious-metal specialist before any flagged item is priced or listed. The shop photographs the item, sends two to four images on WhatsApp 07375071158, and gets a reply within working hours saying whether the item is worth checking further or can be priced as costume. No obligation, no commitment, no money. This guide explains which photos to take, how to lay items out, what we can and can't tell from images alone, and how to set the workflow up so it survives the next staff change. The photo loop is the bit of the system that, if it stays alive, keeps everything else working.

Charity shops can build a beautiful donation sorting process, run impeccable back-room logs and label every tray correctly. None of it generates value if flagged items don't actually get assessed.

The photo step is the assessment loop. A photo on WhatsApp gets a reply that tells the shop what to do next. Without that loop, the "ask first" tray fills up and eventually gets tipped into routine sorting because nobody knows what's actually in it.

For us at the receiving end, the photo step does three things. It lets us identify obvious flag-it-or-don't items quickly, so the charity isn't posting low-value parcels. It surfaces high-value items early, so we can advise on appropriate postal cover. And it keeps the conversation cost low. A WhatsApp message takes a few minutes. A postal valuation takes a few days. Most enquiries get resolved without anything being posted.

For any flagged item, the most useful images are:

Photo 1: Top-down whole item. The full item laid flat on a clean surface, lit naturally or by daylight. A piece of plain white paper or a clean cloth as background. The full item visible in the frame.

Photo 2: Reverse side. Same surface, item flipped over. Shows the back, where most marks live.

Photo 3: Mark close-up. Macro mode if your phone has it, otherwise tap to zoom on the mark before taking the photo. Flash usually helps. Get the mark sharp and large in the frame.

Photo 4: Scale reference. Item next to a coin (a 1p or 5p works), a finger, or a ruler. Gives us a sense of the actual size.

Four photos. Maybe a fifth if there's a maker mark in a different location from the purity mark.

That's it. We can identify most charity items from those four images.

Modern phones can take excellent macro photos. A few simple adjustments make a noticeable difference.

Lighting. Daylight is best. Move to a window if possible. Avoid overhead fluorescent strip lighting which makes silver look greyish and gold look orange.

Background. A plain white sheet of paper or a clean cloth. Avoid patterned or shiny surfaces.

Macro or close-up mode. Most modern phones (iPhone 13+, recent Samsung, Pixel) have a macro mode that activates automatically when you get close. Hold the phone steady, get close, tap to focus on the mark, then take the photo.

Flash. Counter-intuitively, the phone flash often helps with very small marks. The flash creates a bright reflection that picks up worn stamps. Try with flash on and off and use the clearer one.

Steady hand. Rest the wrist against the table or the other hand to reduce camera shake.

Tap to focus, then take. Don't just press the shutter. Tap the screen where the mark is, wait for the camera to focus, then take the photo.

A volunteer who can take a clear macro photo is more valuable to the back room than one with deeper jewellery knowledge. Most enquiries are settled by the photo.

We can usually identify, from a clear photo:

• The purity mark on UK-hallmarked items.
• The assay office and approximate period (Birmingham, Sheffield, London, Edinburgh).
• The maker mark (where it's a recognisable name or initials).
• Whether the item appears to be solid metal or plated, from build cues.
• Whether the item is worth posting for proper valuation, or is likely costume.
• Approximate scrap weight range, where the item's dimensions are clear.
• Recognisable branded items (Cartier, Tiffany, Rolex, Patek and similar).
• Common item categories (Georgian flatware, Victorian silver, Art Deco, mid-century).

We cannot tell from photos:

• Exact metal weight (requires calibrated scales).
• Precise purity for unmarked items (requires testing).
• Whether stones are real or paste (requires gemological examination).
• Exact valuation including market premium (requires inspection).
• Final offer (always subject to inspection at our end).

The honest framing for charities: photo gives us enough to advise on next steps. Final valuation always needs the item in hand.

For a tray of items (the "ask first" tray at end of shift), a single top-down batch photo plus individual close-ups is the most efficient workflow.

Step 1. Lay the tray flat on a desk. Plain background underneath if possible.

Step 2. Spread the items so each one is visible and not overlapping. Items can be touching but not on top of each other.

Step 3. Take one top-down photo of the whole tray. Phone held parallel to the surface, item visible across the whole frame.

Step 4. For each item, take a close-up of any visible mark. Number these in your head: item 1, item 2, item 3.

Step 5. Send all the photos in a single WhatsApp message with a short note: "Hi, [Shop Name], [Town]. Ask-first tray from today's sorting. Eight items, marks visible on items 3, 5 and 7. Any worth posting?"

We can usually reply within an hour during working hours, longer outside.

For full transparency, here's our internal review process when a charity photo lands.

1. Is this UK sterling silver? Look for the lion passant, 925, sterling, the assay-office mark, and known maker marks.
2. Is this gold? Look for 9ct, 14ct, 18ct, 22ct, 375, 585, 750, 916 stamps, plus the colour and build cues.
3. Is this a recognised maker? Mappin and Webb, Walker and Hall, Hester Bateman, Cartier, Tiffany, Rolex, etc.
4. Is this an item type that often has hidden value? Pocket watches, sovereigns, silver photo frames, sterling canteens.
5. Is the photo clear enough to identify confidently? If not, ask for a sharper image.
6. What's the indicative scrap floor? Based on apparent size and weight, what's a rough metal-floor estimate?
7. Is there a reason to recommend posting? If yes, send a prepaid label.
8. Is there a reason to recommend not posting? If the item is clearly costume or plated, say so directly. The charity saves time.

The whole review takes a few minutes per batch. The reply usually fits in a short WhatsApp message with one or two follow-up questions if needed.

Charity manager sends, on a Friday afternoon:

"Hi Rocco, [Charity Name], [Town] branch. Six items from this week's sorting. Photos attached. Worth posting?"

The photos show:

1. A small ring with a partial mark inside the band.
2. A chain, broken at the clasp.
3. A pair of stud earrings (matched).
4. A single cufflink.
5. A small silver-coloured spoon (back not visible).
6. A pocket watch in poor condition.

Our reply, within an hour:

"Hi. Item 1 looks like 9ct, mark hard to read but the cut and weight suggest sterling-grade gold (probably 9ct or 14ct). Item 2 chain looks like 9ct from the colour but I can't see a mark from this angle, can you photograph the small ring near the clasp? Item 3 studs look 9ct, marks visible. Item 4 cufflink is silver-coloured, not gold; can you send a close-up of the back? Item 5 spoon looks plated to me but I can't tell without seeing the back. Item 6 pocket watch is worth posting regardless of metal because the movement may have collector value. Send a clearer photo of item 5 back. Items 1, 2, 3 and 6 worth posting; I'll send a prepaid label. Items 4 and 5 hold while I see more."

The charity gets a clear, actionable reply. The whole exchange takes a few minutes of their time and a few minutes of mine. No money has moved, nothing has been posted, no commitments made. That's the photo loop in action.

Three things kill the WhatsApp loop in practice.

Manager change. The new manager hasn't been told the WhatsApp number, doesn't know the loop exists, and the tray fills up.

Fix. Print the WhatsApp number on the back-room wall. Include it in induction. Add it to the volunteer handbook.

Staff phone changes. The phone used for shop photos breaks or gets replaced. New phone, no WhatsApp history.

Fix. Use a shared shop email or a dedicated phone for the loop, not a personal device. The shop owns the number.

Tray accumulation without action. Items get flagged but the photo isn't sent. The tray gets too full and gets cleared in frustration.

Fix. Pick a regular slot (Friday closing) and make it the photo-sending time. Set a phone reminder. The discipline of the slot keeps the loop alive.

For complete clarity on what charity teams should expect:

• WhatsApp response time. Usually within an hour during working hours (Monday to Friday, 9am to 6pm). Sometimes slower at the weekend or in evenings. We don't promise instant replies because that's not honest. We do promise a reply.
• What we don't do. We don't give exact valuations from photos. We give "yes worth posting" or "no don't post" guidance, plus rough scrap-floor estimates where useful.
• What happens after posting. Full inspection, weighing and testing on receipt. A line-by-line valuation usually issues within one or two working days of receipt.
• What we charge. Nothing for the photo loop or assessment. We make our income on accepted valuations. Declined items are returned by tracked post at no cost.
