Natural, laboratory-grown and imitation gemstones
Keep material identity, natural or laboratory origin, and imitation separate when reading a gemstone description.

Three questions
Begin by asking what material the stone is, how it formed, and how it is represented. A laboratory-grown counterpart can share the chemical and optical properties of the natural material. An imitation resembles a named gemstone while being a different material. These descriptions answer different questions, so avoid treating them as interchangeable labels.
For example, a synthetic ruby is not simply a red object that resembles ruby. Conversely, a ruby imitation should be described by its actual material as well as its visual purpose. When a description is unclear, ask the seller to put the material and origin statement in writing.
A practical description checklist
Read the full description rather than relying on a short title. Ask whether identity was examined, whether natural or laboratory-grown origin was determined, and what treatment information is available. Keep those answers with the report and the individual listing. A photograph of another specimen does not resolve a question about your stone.
Treat an incomplete answer as a missing answer. A seller may have an identification but no treatment assessment. Record the scope of the evidence instead of filling the gap from a familiar name. If the distinction matters to your decision, seek appropriate independent testing before purchasing or setting the stone.
