Mineralogy
Prasiolite is green quartz. The variety name refers to its appearance and mineral identity; it does not automatically describe an untreated color history.

How Color Forms
Selected amethyst material can develop green color after heating, as discussed in Gem-A’s treatment literature. Different green-looking quartz products may involve different materials or processes.
Varieties & Names
Use prasiolite with treatment disclosure. “Green amethyst” is a commercial description that can obscure the distinction between purple amethyst and a green quartz product.
Localities
The cited Gem-A discussion refers to Montezuma starting material for heat-produced green quartz. That treatment example is not a universal origin statement for all prasiolite on the market.
Identification & Treatments
Ask the seller to identify the material and disclose color treatment. Do not infer a natural untreated origin from a pale green shade, a botanical product name or a symbolic association.
Care
For finished bead jewelry, begin with a soft cloth and follow the instructions for the whole piece, including cord, metal and any coatings. Avoid impacts and sudden heat changes. Do not use abrasive home authenticity tests; they can damage a finished surface.
CULTURE & PERSONAL MEANING
Cultural Symbolism
Zoe Gems uses heart as contemporary symbolic connections. The Five Elements association is an editorial cultural interpretation. These are personal meaning-making frameworks, not measured mineral properties or evidence of medical benefit.
Five Elements Connections
These associations are not treatments and do not replace healthcare.
