Keep the Label That Came with Your Mineral

A mineral can survive a move while its history disappears. Preserve the link between specimen, old label and purchase record, without turning an uncertain locality into a confident claim.
A seller offers a small mineral collection in separate boxes. Several specimens have handwritten labels; others have only names. You could replace the cards with a tidy matching set, but first make sure the old information will survive the tidy-up.
A collection becomes harder to understand when records no longer belong to identifiable specimens. “Quartz, Brazil” may be a modest description, yet it is still more useful than a locality remembered later and attached to the wrong piece.
Ask for the records as part of the purchase
Before paying, ask whether the existing labels and any relevant purchase records are included. If the seller calls a piece “from an old collection”, ask what supports that description. An earlier collector's label, a dealer's recent note and an unattributed recollection are different kinds of information.
You do not need to settle every historical question before buying a specimen for its appearance. You do need to know which part of the description is established and which part you are accepting as a seller's account.
This becomes particularly useful when you collect by locality. The Natural History Museum of Los Angeles offers separate species and locality searches for its mineral collection. A mineral name and a place name support different ways of finding and comparing specimens.
For your own purchase, “Brazil” and a named mine are not interchangeable levels of detail. Ask for the more precise information if the collecting purpose depends on it. If it is unavailable, record the broad description you actually received.
Make one link before you make a beautiful display
Assign a short, unique reference to each specimen. Put it on the box and on your record card, then photograph the specimen beside its original label and that reference. Include a view that makes the piece recognisable: the outline of the matrix, a particular cluster of crystals, or an existing chip may help distinguish it from a similar specimen.
This is a practical way to keep the right information with the right object. It does not authenticate the locality, and there is no need to write a number across a crystal face to make the system work.
Keep the original wording in the record. Add the date you acquired the piece and who supplied it. If a locality is a dealer's attribution, say so. Later notes can have their own dates rather than being blended into the original account.
A photograph alone cannot replace everything. It may preserve a legible label beautifully, but you must still be able to identify the photographed specimen after moving it from its old box. Take the reference with it when you change the display.
Leave the blanks honest
The US National Park Service's natural history collections handbook instructs staff not to guess missing label data and to retain old labels. Those are museum procedures, but the underlying habits also suit a small private collection.
If all you know is the country and seller, that is what you should preserve. Finding a similar-looking specimen online does not establish that yours came from the same mine. A blank is an invitation to investigate; an invented locality can send that investigation in the wrong direction.
If a later examination changes the mineral identification, add the new finding, its source and its date. Keep the earlier card. You will then be able to explain both the correction and the history of the description.
Good records will not promise a resale price. They make the specimen easier to discuss, compare and pass on. When a friend asks where a piece came from, you can give the information you have, rather than the story you wish had stayed in the box.
