This is a longer, more involved process of growing gems, however it provides many advantages. The most important being an identical internal structure that gives each MiaDonna gemstone optimal brilliance and light return.
The less advanced, alternative growing process of Flame Fusion uses a melting method to achieve a stone that carries the same look as a Ruby and/or Sapphire. This is what you will find at most competitors because it's the most commonly used method due to the low investment (approximately 1 cent per carat) and the quick turnaround (approximately 1 hour), however the lack of internal crystal structure means it will not carry the same brilliance as a natural Ruby or Sapphire, and will return a negative result when tested.
