Dalmatian Jasper vs Granite
Dalmatian Jasper and Granite are easy to confuse. Both sit near Mohs 7, so a scratch test alone will not separate them. Lean on luster, streak and heft instead. Below is a side-by-side comparison of their properties and the quick tests that separate them.
Key differences between Dalmatian Jasper and Granite
- Both sit near Mohs 7, so a scratch test alone will not separate them. Lean on luster, streak and heft instead.
- Streak color differs: Dalmatian Jasper leaves a white streak on unglazed porcelain, Granite leaves variable; test individual minerals.
- Luster is different: Dalmatian Jasper is waxy while Granite is vitreous.
- They overlap in white and black, but Dalmatian Jasper also comes in brown and Granite also comes in pink and gray.

About Dalmatian Jasper
Dalmatian Jasper, also called Dalmatian stone, is a cream to tan spotted lapidary material commonly sold under the jasper trade name.
About Granite
Granite is a coarse-grained igneous rock composed mainly of quartz, feldspar, and mica. It's one of the most common rocks in Earth's continental crust.
