Methods of fabricating polycrystalline diamond elements and compacts using sp2-carbon-containing particles are disclosed. In an embodiment, a method of fabricating a polycrystalline diamond element includes mixing a plurality of sp2-carbon-containing particles and a plurality of diamond particles to form a mixture. An amount of the plurality of sp2-carbon-containing particles present in the mixture is effective to increase a thermal stability of the polycrystalline diamond element formed at least partially from the mixture. The method further includes sintering the mixture in the presence of a catalyst material to form the polycrystalline diamond element.
