These are lab created Czochralski pulled orange sapphire facet rough. It has a rich, even color with no zoning.
Sapphire is an ideal material for gem and industrial usage alike. Its high hardness and incredible range of colors means it can be used for everything from bearings to gems to solid watch cases. These pieces have a rich orange color which shifts a bit towards pink-orange in some lights. These are absolutely gorgeous gems.
These are czochralski grown, a more expensive and demanding growth method that produces crystals of high chemical purity and structural perfection which are suitable for technical applications. Unlike many of our materials these were likely grown for a less typical usage: ultra high end watch cases. Cases milled out of solid sapphire are incredibly durable but require large crystals of high quality sapphire free of defects so they get grown on the same production lines that produce industrial grade material--in fact this grower normally makes optical filter materials so this was an unusual run for them. Fortunately for us they also produce offcuts which we can save and repurpose for gem usage.
