Search mineral by feature
Search for the precise term. The term can also occur within a word. Search for gelb (yellow) will also find zitronengelb (lemon yellow) for example. To assist you, proposals will be shown on the right. At least one search criteria must be specified. Unfortunately you can only search for german search terms at the moment.
The more boxes filled the lower the results. Too many criteria may also lead to an empty result. You can locate the results (just type in part of the locality/region name and then select) to the corresponding mineralogy.
