Blue Dumortierite Crystals from Mozambique
Finely polished dumortierite crystals carefully chosen for our collection of rocks and minerals.
These dumortierite tumbled stones are a lower grade because of visible inclusions of other minerals.
Many rocks and minerals are graded according to the lack of or presence of inclusions.
Dumortierite is quartz heavily included with crystals of dumortierite. It's sometimes called blue quartz, which is not correct.
We also have grade-A dumortierite tumbled stones as part of our collection.
These dumortierite crystals are medium-sized tumbled stones, but size can vary from piece to piece. This is common for stones produced in a rock tumbler.
For smaller quantities, we'll choose larger stones, but for larger quantities, sizes will be mixed.
