Silicon Specimen Pieces

Silicon Specimen PiecesThese are lab made pieces of purified silicon, 99. 999% pure polycrystalline material made in Germany. Some pieces show the surface of the ingot, where cooling formed different crystal structures. Others have just fractured and show the natural gray black of silicon. They are neat little artifacts of science. Silicon is famously used in all sort of computer chips and other technical applications, and large silicon monocrystals have driven the

is all black

It can be used to make lasers with tunable output wavelengths and especially powerful

These stones have a very bright green-yellow fluorescence which gives them a super bright and almost uncanny glow in some lighting

These were grown in a sodium-molybdenum oxide flux mix

It weighs in at 10ct and measures 14mm in diameter

I'll have to do another Minecraft diamond but for now this one is available

though you can get neat effects by orienting them differently as well

some are a little tinted

In addition to the pink color it also has surprisingly strong green fluorescence under UV

This is a pendant featuring a custom cut blue laser garnet

4 mm thick

These are lab created golden laser garnet aka Ce+Nd YAG (Yttrium Aluminum Garnet) facet rough
