These are lab created Czochralski pulled green sapphires. The pieces are labelled with their letters and weights and can be purchased individually.

We finally got some fancy colored sapphires! These are all 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.  Fortunately for us they also produce offcuts from the edges and ends of the boules which we can save and repurpose for gem usage.

These have a nice minty green color or a richer blue-teal hue. Per the grower it is colored by iron, cobalt and vanadium, an unusual combination with a stunning look.
