Boron Cantilever and Ruby Cantilever, Why Ruby?

I have noticed that many of the better cartridges use Boron cantilevers. I know that Soundsmith uses a Ruby cantilever. I was thinkin of having my Benz Wood Body cartridge retipped but was not sure if the different material used for the cantilever will impact compliance and even sound. Why not boron like the original?

Ruby is just a red Saphire. I am sure they use synthetic Corundum why not the blue or yellow??

Berylium is toxic if it is inhaled only. Thus you can have Be tweeters and so on because the Be does not become airborne.
Dhl93... I used to work in the Jewelry business and have a GG. Niether Saphire or Diamond as a crystal is particularly " very brittle and fragile." How many Diamond rings have you seen break apart? Diamond cantilevers must be the crystaline form to be called "Diamond" otherwise it is just carbon.
