The key point
Compare photographs of the exact stones under the same conditions, with front, back and side views. Images support appearance and condition checks but cannot establish mineral identity or guarantee a precise color match on your screen.
Request a useful set
Ask for exact-piece photographs with a neutral background and size reference, front and back, edges, and a short video. Show matching pairs together. Establish whether photos depict stock examples or the reserved item and keep approved images with the order.
Control comparison
Use similar lighting, distance, and backgrounds. Nearby colored objects can reflect in polished surfaces. Highlights can hide features. Several angles help separate reflections from persistent features, although images cannot establish mineral identity.
Ask about adjustments
Exposure correction and cropping can improve documentation. Ask whether saturation, contrast, or other adjustments affect color. Photographs cannot guarantee identical color on all screens. Agree an inspection or sample process when a precise shade matters.
Inspect delivery consistently
Compare dry material under neutral light, using IDs and measurements as well as appearance. Photograph arrival condition. Report concerns in the agreed period and avoid modifying questioned material before the seller can respond.
A repeatable comparison session
For two candidate stones, request one photograph showing both together, dry, on the same neutral background. Keep lighting, camera position and exposure consistent, then add separate front, back and side views. Avoid mixing a wet rough close-up with a dry polished stone from another session. Record item IDs and which images belong to each session. This procedure improves relative comparison; a neutral background or color reference does not turn an uncalibrated phone photograph into an exact color measurement.
Separate a moving reflection from a persistent feature
Request a slow rotation with the whole item in frame. A bright highlight may move across the surface as the angle changes; a line remaining in the same location deserves a closer view. Neither observation diagnoses a fracture by itself. Ask for another angle and an examiner’s description when condition affects the purchase. For mounted jewelry, include the underside and attachment points: a beautiful front view says little about the parts that hold the stone.
When photographs are insufficient
If exact color matching, a suspected surface issue or setting fit is essential, agree an inspection, sample or independent examination before final acceptance. A short video reduces some uncertainty but cannot prove identity, treatment status, hidden condition or precise fit. At delivery, compare the item ID, dimensions and visible features with the agreed record before comparing color from memory. Keep the original files and arrival photographs; distinguish a documented discrepancy from a difference caused by lighting or display.
