	Diamond (the fist gemstone like material where strong [[surface passivation]] was known to be possible) does not really degrade when left alone as waste in nature (escaping the [[recycling]] process), filling the background behind sliding interfaces with degradable material is a bad idea. If that background is eroded away left over are persistent nanoscale diamond "skin flakes" that are likely very damaging to the environment (food chain). Even a solid non-degradable block of diamond would be better than that.
