Elbaite vs Schorl
Elbaite and Schorl are easy to confuse. Both sit near Mohs 7–7.5, 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 Elbaite and Schorl
- Both sit near Mohs 7–7.5, so a scratch test alone will not separate them. Lean on luster, streak and heft instead.
- Streak color differs: Elbaite leaves a white streak on unglazed porcelain, Schorl leaves white to grayish.
- Hold a thin edge to the light: Elbaite is Transparent to translucent, Schorl is opaque.
- Well-formed crystals give it away: Elbaite is Trigonal, Schorl is trigonal.

About Elbaite
Elbaite is the most common gem-quality species within the tourmaline mineral group, a complex borosilicate rich in sodium, lithium, and aluminum with the formula Na(Li,Al)3Al6(BO3)3Si6O18(OH)4. It produces one of the widest color ranges of any gem mineral, including pink, green, blue, and the bicolor watermelon tourmaline prized by collectors. Elbaite takes its name from the island of Elba, where fine crystals were first described.
About Schorl
Schorl is the common black, iron-rich member of the tourmaline group. It forms striated prismatic crystals with a rounded triangular cross-section and is by far the most abundant tourmaline species in nature.
