Choosing a specimen
A well-formed crystal, an unusual association or a balanced cluster can catch our eye. We also look at condition and the recorded locality. These details help you decide whether a specimen belongs in your collection.
Selection philosophy
We consider how the crystals have grown, how they sit on the matrix and what can be seen from the display angle. Condition and locality also matter. Our selection reflects collector judgement; we do not use a laboratory grading scale.
What the specimen contains, using the most accurate verified identification available.
Crystal form, habit and the way the mineral has developed.
How primary and associated minerals occur together.
Composition, display orientation, contrast and visual character.
Visible condition and disclosed repair or treatment information when supplied.
The usefulness and confidence of the specimen’s recorded origin.
Scientific, locality, morphological or aesthetic reasons a specimen may merit attention.
