Not fluorescent.
Other Information
Special Storage/
Display Requirements:
Display Requirements:
Crystals easily dehydrate, especially under a microscope lamp, and become ivory-coloured. It is suspected that only water which is hydrogen-bonded and not ligated to a metal are lost.
Health Risks:
No information on health risks for this material has been entered into the database. You should always treat mineral specimens with care.
