Jadeite vs Nepheline
Jadeite and Nepheline are easy to confuse because both are silicate minerals. Both sit near Mohs 6.75, 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 Jadeite and Nepheline
- Both sit near Mohs 6.75, so a scratch test alone will not separate them. Lean on luster, streak and heft instead.
- Jadeite feels noticeably heavier for its size (specific gravity 3.3 versus 2.6 for Nepheline).
- They overlap in green and yellow, but Jadeite also comes in white, purple, and black and Nepheline also comes in clear, gray, and red.
- Well-formed crystals give it away: Jadeite is monoclinic, Nepheline is hexagonal.

Which is more valuable?
Jadeite is usually the more valuable of the two: a typical collector specimen runs about $600 against $30 for Nepheline, and premium Jadeite can reach $15000 or more.
About Jadeite
Jadeite is a sodium aluminum pyroxene and one of the two minerals known as jade. As a tough, interlocking aggregate it ranges from white to vivid emerald green, and the finest translucent green material is the most prized form of jade.
About Nepheline
Nepheline is a sodium and potassium aluminosilicate of the feldspathoid group, found in silica-poor igneous rocks. It usually appears as gray, greasy-looking masses and grains rather than well-formed crystals.
Jadeite vs Nepheline FAQ
Is Jadeite the same as Nepheline?
No. Both are silicate minerals, but they are distinct species with different hardness, streak or luster. Both sit near Mohs 6.75, so a scratch test alone will not separate them. Lean on luster, streak and heft instead.
How can you tell Jadeite from Nepheline?
Both sit near Mohs 6.75, so a scratch test alone will not separate them. Lean on luster, streak and heft instead.

They overlap in green and yellow, but Jadeite also comes in white, purple, and black and Nepheline also comes in clear, gray, and red.
Which is harder, Jadeite or Nepheline?
Jadeite is harder: Mohs 6.75 against Mohs 6 for Nepheline.
Which is more valuable, Jadeite or Nepheline?
Jadeite is usually the more valuable of the two: a typical collector specimen runs about $600 against $30 for Nepheline, and premium Jadeite can reach $15000 or more.
