JEWEL DAILY perspective
Our reading: origin can enrich a stone’s story but cannot replace an assessment of the actual object. Explain origin, treatment and visible quality separately; stones from one location can differ substantially.
Update submission checklists to confirm eligible materials, wording, fees and timing. Do not change an existing stock item’s origin description simply because a laboratory has expanded its services; the individual stone needs a supporting result.
