General Notes
Richardsite is listed as "unconfirmed / questioned" on Mindat (https://www.mindat.org/locentry-1418207.html; accessed April 2023). It was tentatively identified by Joy Désor but with the caveat that more precise high resolution analysis is required to confirm richardsite which apparently occurs as an exsolution product in an unspecified host phase.
Questionable status is retained pending further information and analysis.
