Beryllium Mirror Cube

349.00

Beryllium is so far the only metal cube we offer which is mirror polished by default - there is no regular ground polished option. This is not by design. It just happens that this metal takes a high polish easily in the flat lapping stage so no point nor cost savings in offering a lower level of polish.

Beryllium also takes the cake for most difficulty in securing a factory who could get the job done. While the later stages pose no problem the earlier ones are a much different story. The metal is rare and costly in bulk so the trials involved small pieces to limit loss. It was discovered early on that attempts at grinding was damaging the tools and the filings are known to be a health hazard.

You can find a more complete writeup of the process on the metal cubes section if interested but, regardless, just know that with one of these you’ll be getting a special item indeed!

Weight of each 10mm cube is 1.80±0.03g
