In my experience at least (which isn’t more than about a decade), all the lab materials polish like their natural counterparts–that’s partly why I teach on synth garnet (YAG/GGG). If anything, the synthetics are more predictable and it’s the naturals you have to worry about–for example, directional hardness in natural sapphire.
