Using the Search Form
All specimens for sale on the web site are entered into a database. The search form allows you to specify criterea to select the specimens you wish to view.
The form has a set of fields for you to fill in. You may fill in one or more of the fields. If you fill in more than one, then only specimens satisfying all fields will be returned. (Empty fields match all specimens).
For the type-in text fields, the value you type in is matched against the values in the field for each specimen in the database. Since it's a pattern match, it's ok to type in partial values. For example, when searching localities, if you simply enter "China", you'll select all speciments from anywhere in China. If you type in "Colorado, USA", you'll get all specimens from the state of Colorado in the United States.
You can limit the search to specimens that were added during some interval or prior to that interval. For example, selecting "Before" and "10 Days" will search specimens added prior to the last 10 days. Selecting "Since" and "10 Days" will search specimens added during the last 10 days.
Each specimen has a unique alphanumeric ID, for example, "CK42", or "URI-01". You can limit the search for specimens whose IDs contain a given string of characters by specifying it here. You can indicate if you would like "Partial Matches". For example "K-112" would match "K-112" and "HECK-112". Or you can uncheck the "Partial Matches" box to only retrieve exact matches.
Each specimen has a name field. Often the name is just the name of the primary mineral(s) of the specimen. But in some cases, there are conventions that can be useful in finding what you are looking for. For example, all pseudomorph specimens will the string "after" in their names, so you can find all pseudomorphs by entering "after" in the Name field. Be aware that the name field might include variety names ("amethyst", "aquamarine", etc.). Thus, to be sure of finding all Beryl specimens, select Beryl in the Mineral field - not in the Name field.
The Species field is different from the Name field, in that it searches the list of species occurances noted for each specimen. (Not the species names that happen to be in the specimen name!) It is more precise than searching for species names in the Name field. For example, if you search for just "A" in the Name field, you will find Albites, Amazonites, Azurites, and so on... if you search for specimens by specifying a Species in the Species drop-down menu, the only specimens noting a occurance of that species will be selected. The Species field allows IMA-approved species names, only. (E.g., you'll find Quartz, but not Amethyst).
The locality field is populated with locality names. Spellings and the locality hierarchy are generally as presented in the locality listings at www.mindat.org.
Of course, you can also search by any part of the locality name, for example, "Sweet Home Mine" would find all specimens from a specific mine.
The Description field seaches in the specimen descriptions. Since previous owners are usually named in the description, you can search for "Arthur Montgomery" to look for specimens sold by the noted American mineralogist (or perhaps even from Montgomery's personal collection).
Allows you to search based on the specimen sizes.
By filling in these fields, you can limit the search to a particular price range. For example, with "Min Price" 1000 and "Max Price" of 2000, the search will only match specimens in this price range.
Allows you to constrain the search to specimens formerly in the collection of one of the listed collectors or institutions.
Searches are "bookmarkable". After clicking "Search", and receiving results, you can bookmark the result page, and your bookmark will store the search. Remember, revisiting the bookmark will re-execute the search; it does not store the search results. If the contents of the database have changed since the search was originally stored, the results may change.
