Mineral Collecting with a Purpose


Most of us appreciate the beauty of minerals.  And, many of us will purchase individual mineral specimens that we find compelling.  We at Crystal Moon Gallery would like to suggest that mineral collecting with a specific purpose or objective in-mind can be educational, motivational, and Fun!

If one studies mineralogy, there is a potential to be entirely overwhelmed by the sheer magnitude of the field.  Many thousands of mineral species have been discovered and identified.  And the subtleties!  A single atom can significantly change the composition of a mineral...and result in a new mineral species.

And, let's not forget that some minerals are not very good for your health!  And, others are not very stable.  Cinnabar, a Mercury Sulfide, sometimes 'bleeds' elemental Mercury.  Realgar, an Arsenic Sulfide, forms beautiful deep-red crystals, but can alter to powdery yellow Orpiment or Pararealgar upon long-term exposure to air and light (which can be mitigated with specialized storage).

Collecting with a purpose allows one to: (1) narrow their focus to only those minerals of intense interest (2) establish themself as a local expert (3) avoid dangerous or unstable minerals (4) be motivated to find that next piece of the collection.

Collectors take a wide variety of approaches.  Following are some which we have seen first-hand:
  • Fluorescent minerals.  Some minerals exhibit entirely different colors and textures under UV light.  Fluorescent minerals deliver bright colors, and a really unusual way of seeing minerals.  However, fluorescent minerals require special lighting.
  • "Type Localities".  Many minerals are historically documented such that the first discovery is known.  Minerals from the location of first discovery/identification are the goal of this collector.  For example, Ajoite was first identified and named-for the Ajo mining district in Pima County, AZ.  Type locality collecting can allow wondrous variety in a collection, while keeping to a main theme.
  • Unique species or groups.  We know one fellow who collects only the Garnet group of minerals.  With numerous unique species, and almost every imaginable color (except blue), the garnet group can deliver an amazingly colorful collection. 
  • Crystal systems.  Most minerals form in a distinct pattern (e.g. Quartz is usually Hexagonal, and classified as such).  And some enjoy a collection of varying shapes in which minerals crystallize.  A variation would be a collection of crystal oddities...minerals that crystallized into unexpected shapes.
Not surprisingly, some will combine two or more of these example strategies.  For example, crystal oddities in the Quartz family could be a reasonably inexpensive and diverse collection.  The photo at the top of this post is of "skeleton" quartz (sometimes called window, jacare, or elestial quartz).  The steel pin is about 1 3/4" long, and is inserted about one-third of its length into an open chamber in the quartz crystal.  The prevailing theory is that the outer walls of the crystal grew more quickly than the inner areas, creating an enclosed, hollow, inner space, with an opening to the outside.

Here are Crystal Moon Gallery, we try to offer a wide variety of safe and stable mineral specimens.  And, we know quite a number of mineral dealers and collectors.  So that we can help you to fill-in the gaps in whatever collecting strategy you chose.
