For sale is an excellent specimen of blue, cobalt spinel, from Vietnam. The color of the crystals is top notch, with the main crystal being of well set on the matrix. A quick check of mindat will show how uncommon these cobalt spinels are, the two examples shown have neither the saturated color of the luster of this piece. These come from just a couple of deposits, each about the size of half a football field, and then they are found only sporadically, with very very few being dug in the last six years. A perfect small gem octahedron spinel crystal can be seen in a couple of the pics. The largest crystal is 11mm long. We obtained this specimen on our last visit to the mines of Luc Yen, in 2019. Please remember our prices are in Australian dollars.
