Testing gold the right way: six tips for a better scan

If you are checking a family heirloom, a flea-market find or something from the back of a drawer, the photo you take decides how much the analysis has to work with. Six things make most of the difference.

Why photo quality decides the result

IsItGOLD? reads visual evidence: colour, surface texture, wear, shape and above all any markings. Blur, glare and poor light remove exactly that evidence, and a photo with too little of it either produces a vague answer or gets rejected outright.

Preparing the object properly takes a minute and is the highest-return minute in the whole process.

The six that matter

Light. Daylight, or a bright white lamp. Avoid warm bulbs — they tint everything gold, which biases the one judgement you are asking for. Soft light from the side beats hard light straight on.

Stability. Hold the phone still or rest it on something. Camera shake costs you the fine surface detail that distinguishes solid metal from plating.

Focus on the detail. Move close and tap the screen to focus on the stamp or engraving. Check the photo before you submit it. If the stamp is not readable on your screen, it is not readable to the analysis either.

A neutral background. Black fabric or white paper. A busy surface competes with the object for attention and makes the edges harder to read.

Several angles. The guided scan takes multiple photos of one object, so use them: the whole piece, the reverse or underside, and a close-up of the hallmark. Different angles that show different things are worth far more than three near-identical shots.

Clean it first. Wipe the piece gently with a microfiber cloth. If it needs more, a little isopropyl alcohol (70% or higher) lifts oils and dirt. Do not submerge it and do not scrub — you are trying to reveal the surface, not resurface it.

Then add what the camera cannot see

Two inputs do more than any further photo:

• The weight, from a tared scale. It changes the estimated value range more than anything else you can provide.
• A short, factual description of where the piece came from and anything stamped on it.

What a good photo can and cannot buy you

A careful scan gives you a well-founded estimate and a much clearer idea of what to do next. It does not confirm purity, and it is not an appraisal. If the answer matters financially, treat the scan as the reason to get an independent test — not as a substitute for one.
