Few combinations in the natural turquoise world are as visually compelling as vivid green against deep mahogany matrix — and this piece delivers exactly that.
The warm reddish-brown of the host rock is a natural iron-oxide staining within the limestone formation at Cortez Canyon, Northern Nevada. Against the zinc-driven lime green of the turquoise, it creates a contrast that photographs beautifully and holds attention in any collection.
Weight: 6.05g
Form: Natural rough / specimen with matrix
Origin: Cortez Canyon, Northern Nevada
Treatment: None — 100% natural, never stabilized, never dyed
The mahogany matrix on this piece is structurally part of the original limestone host rock — it’s not a surface feature. That means it cuts cleanly for lapidary artists who want to incorporate the matrix into finished cabochons or freeform pieces.
Perfect for: Collectors who prize natural matrix character, lapidary artists looking for high-contrast rough, or anyone who wants a stone with strong visual identity.
This is the kind of piece that looks like it was designed — it wasn’t. That’s just what Cortez Canyon produces.
