What are you going to collect?
The first thing to decide on when starting a mineral collection is what it is exactly that you are wanting to collect. Will you collect from a specific region or locality? A specif species or family of mineral? Anything that takes your fancy? Particularly when starting a collection for a child, you may even start a collection of whatever can be found locally. Whatever you decide on, it is important to pick rocks that are attractive to you and pieces that you find to be unique in some way; After all, this is YOUR collection.
Regardless of what you are collecting, be it rocks and minerals or stamps or coins or anything, proper organisation and display plays a key part in the process. The basics of organisation in mineral collecting are:
Identification - Once you have a mineral specimen, you need to properly identify it. There are countless amounts of species from countless amounts of localities. Where does your specimen come from? What species is it? What variety is it? The first and most important step in organising your collection is proper identification.
Labeling - Once you have properly identified your specimen, you need to give it a label. if you are considering entering mineral competitions down the track then there is certain information which is required on your label:
  • The species name(s) (which should be in CAPITALS).
  • Don’t use common names (such as ‘Tourmaline’) but rather use the specific species name (Tourmaline could be Schorl, Dravite, Elbaite etc). Names listed in the book ‘Fleischer’s Glossary of Mineral Species’ are widely accepted
  • Specimens like Amethyst should be labeled as 'QUARTZ var.Amethyst'. It is generally acceptable at competitions to Always place the SPECIES name first in CAPITALS and the variety name second in lower case.
  • It is important that you have your locality details as accurate as possible (i.e Country, locality, mine name etc). For overseas specimens a region and country are generally accepted at competitions if you don’t know the name of the mine. 
Other information that you may like to include on your label are the specimens common name (if you know it), where it was found and the date it was collected.  Labeling your collection pieces can help you organise them into groups and store those groups together in your display.

Cataloging - Cataloging is basically an extension of your labeling system.  A catalog is a written archive of your collection which can be referred to when needed.  Each specimen has its own label which identifies it and your catalog keeps a record of all those labels in one reference point. Your catalog can be particularly helpful if you include information such as where the specimen is stored or displayed. Other information that you could include in your catalog is:
  • A unique specimen number
  • Where you obtained the specimen from and how much you paid for it
  • Weight, size, size of individual crystals etc

Display - Displaying your collection helps you show it off - By displaying your specimens both you and others can appreciate their natural beauty. It is important to display each piece along with its label so you and others can identify each piece easily.

Barite Crystal Cluster - A piece from my mineral collection

This piece is a specimen of Barite Crystals and came from the Meikle Mine, Bootstrap, Elko County, Nevada, USA. I purchased this piece a number of years ago and it remains one of my favorite collection pieces.
