and it has been a popular gem since the first natural deposits were discovered in Russia

aka iron-doped lithium niobate

The crystals require a great deal of trimming and annealing but they are getting better and better

They are grown by a top US photonics company and a laser built around one of these will be on the 2028 Mars rover(
