I don't know what was meant by one-piece stylus and cantilever, but, if it really means starting with a single diamond that is then cut to form the stylus and cantilever, that diamond would have to be pretty low-grade to start with in order for the price to be anything but astronomical. High quality stylus are made from decent quality natural stones with the cutting and shaping done so that the lattice structure is properly oriented to maximize resistance to wear along the contact points. You could not really do this with a truly one-piece stylus-cantilever diamond.
Does anyone know if the diamond cantilevers were solid pieces or a hollow tube? For any given mass, a tube would be the way to go to maximize strength and rigidity (better to have a fat tube than a thin solid piece of the same mass).
Given that there are buyers out there that will pay almost any price for something special, I would expect that, if diamond cantilevers where inherently superior, many of the premium builders would be offering that feature on their ultra expensive models.
