Where to find Mixed Tumbled Stones
Worldwide
As tumbled stones are manufactured from raw materials sourced globally, their 'finding locations' are essentially the mining sites of the individual minerals. Major sources include Brazil (amethyst, quartz), India (aventurine, jasper), Madagascar (rose quartz, jasper), Mexico (fluorite, obsidian), USA (various quartz, jasper), and many other countries with significant mineral deposits.
Collecting tips
- Source from Reputable Dealers. When purchasing mixed tumbled stones, buy from reputable dealers who can accurately identify the individual stones and provide information on their origin, if desired. This helps ensure authenticity and quality.
- Examine for Quality. Look for stones with a good polish, free from significant cracks, chips, or dull spots, unless these are natural features of the stone (e.g., druzy inclusions). The color should be vibrant and consistent with the mineral type.
- Consider the Mix. Different suppliers offer different 'mixes' of tumbled stones. Some may focus on specific color palettes, mineral groups, or price points. Choose a mix that aligns with your intended use or collection goals.
- Beware of Fakes/Synthetics. While less common with basic tumbled stones, some rarer or more expensive minerals might be imitated. Familiarize yourself with common fakes for specific minerals if you are looking for particular types within a mix.
