They are minerals selected for their aesthetics, rarity or scientific value. The most appreciated characteristics include:
- Color : Vibrant and distinctive, like the blue of azurite or the green of malachite.
- Crystallization : Well-defined geometric shapes.
- Transparency and brilliance : As in quartz or fluorite.
- Rarity : Unique or difficult to access specimens.
