Begin with the material name
Chrysoprase is a green variety of chalcedony, with its characteristic colour associated with nickel. The name identifies a material variety rather than a general shade for every smooth green gem. In gemstone jewellery, keep it separate from jadeite, nephrite and other green materials. Similar colour or a rounded polished shape does not make those names interchangeable.
Compare the particular appearance
Look at the actual stone's colour distribution and how much light it transmits. A bright close-up against a pale background can create a different impression from the same piece worn against clothing or skin. Request consistent views where possible and describe the green you prefer in ordinary language. Preference does not require you to identify an unknown stone from a screen.
Ask the remaining questions
The variety name alone does not establish country of origin, treatment status or the making process of the finished jewellery. Read those details separately and seek clarification if a seller uses several material names in one description. A report, where supplied, should be read for its actual scope rather than treated as evidence for information it does not state.
Consider the shape and frame
A smooth green surface may become the main colour area in a design, while the surrounding metal defines its edge. Compare the stone's dimensions and the overall piece instead of choosing only by a colour swatch. In CIELA's jewellery selection, use the individual material specifications; a photograph of a green stone does not establish that it is chrysoprase or that a particular variety is currently offered.
