1. A prosthetic joint component comprising:

  • a first joint member, a first joint member solid sintered polycrystalline diamond compact, said first joint member solid sintered polycrystalline diamond compact being solid diamond absent a substrate sintered thereto, diamond crystals located in said sintered polycrystalline diamond component, chemical bonds between diamond crystals in said sintered polycrystalline diamond compact, a crystalline diamond structure located in said sintered polycrystalline diamond compact;

    said first joint member solid sintered polycrystalline diamond compact having an exterior surface serving as a first joint member load bearing and articulation surface, said first joint member load bearing and articulation surface having a bearing material that is primarily sintered polycrystalline diamond compact, said first joint member load bearing and articulation surface being non-planar, said first joint member load bearing and articulation surface having a smooth and durable surface for articulation in a prosthetic joint, a second joint member, a second joint member load bearing and articulation surface, said second joint member load bearing and articulation surface being shaped to be complementary to the shape of said first joint member load bearing and articulation surface in order to accommodate movement of said first joint member load bearing and articulation surface against said second joint member load bearing and articulation surface, said second joint member load bearing and articulation surface having a counter bearing material, said counter bearing material having the capability of articulation against said first load bearing and articulation surface bearing material, and said counter bearing material being free from diamond.
