A sample is not only a visual approval. It is the point where a jewelry buyer checks whether the reference, stone specification and factory execution now describe the same product.
Review the 925 silver mark where applicable, stone shape and size, symmetry, prong or bezel finish, polishing, plating tone, clasp function and the overall balance of the piece. Compare these points with the approved reference and written brief rather than relying on one product photo.
Record every change in one final sample note: dimensions, plating color, logo placement, packaging and approved photos. That note becomes the most useful bridge from CAD and sample to bulk production.
