Yes. One example is quartz with olivine. They react to form orthopyroxene, so you never found them coexisting in a magma.
There are other example in igneous, metamorphic rocks and in some ore deposits. Like bornite-pyrite, is also not compatible in porphyry copper type deposits.

"Generally, crystals form when they undergo a process of solidification. Under ideal conditions, the result may be a single crystal, where all of the atoms in the solid fit into the same crystal structure. However, generally, many crystals form simultaneously during solidification, leading to a polycrystalline solid."
Sorry, I followed some of the links from the site below, but I couldn't find anything about crystals that are incompatible.

A diamond. It is the most beautiful. It is by far the hardest. I think it is approximately 10 times harder than the second hardest mineral corundum. It is a wonderful material. I wish I had a ton ot it.
Oops I read that comparable.
