Collecting tips
- Identify the Source Material. When purchasing, try to identify the original mineral or rock. This will inform you about its properties, potential hazards (e.g., malachite dust), and geological significance.
- Examine the Polish Quality. A good tumbled stone will have a uniform, high-gloss polish with no dull spots, scratches, or pits, unless these are natural inclusions of the original material.
- Check for Dyes or Treatments. Some tumbled stones, especially agates and quartz, may be artificially dyed to enhance color. Ask the seller or look for unnaturally vibrant or uniform colors that might indicate treatment.
- Consider Hardness. Softer minerals (e.g., fluorite, calcite) will show wear and scratches more easily than harder ones (e.g., quartz, jasper). This is important for durability if used in jewelry.
