Identify and grade Larimar

Color attracts attention; evidence establishes identity. This section explains how to move from “it looks like Larimar” to a description that is useful, repeatable and honest.
Identification, grading and valuation are related, but they are not the same task:
- Identification asks what the material is.
- Provenance asks where it came from and how that history is documented.
- Grading describes the quality and character of the material under a stated system.
- Valuation considers grade together with size, workmanship, rarity, condition, documentation and market demand.
A dark-blue color does not prove that a stone is Larimar. A certificate does not automatically prove that every statement printed on it is independent. A high grade does not automatically produce a high value if the piece is damaged or poorly made. Gemstones, like people, become less confusing when we stop asking one label to do five jobs.
