What is Lab Grown Hydrothermal Cobalt Spinel?
Cobalt Spinel Process method is made by hydrothermal growth (newest “Platinum” technology) which is slow and only method for successfully growing synthetic cobalt spinel. This process requires heat and pressure and imitates the conditions deep in the earth that result in the formation of natural gems. Nutrients are dissolved in a water solution, and then synthetic crystals form as the solution cools to produce a cobalt spinel gemstone.
