Turquoise is the blue stone dominating your display — including that big upright slab in the back. How to recognize it Blue to blue‑green color Brown or black veining (“matrix”) Waxy or matte surface when polished Often found in nodules or seams What it is
A copper‑aluminum phosphate mineral that forms in dry, copper‑rich regions.
Your pieces show both: polished turquoise (smooth, bright blue) rough turquoise (more greenish, with matrix showing) The deep green stones with banding and swirls are malachite. How to recognize it Bright to dark green Concentric rings or stripes Smooth, glassy polish Heavy for its size What it is
A copper carbonate mineral that forms in the oxidation zones of copper deposits.
Your pieces show classic botryoidal malachite — rounded, layered growth. Some of the blue‑green pieces that aren’t quite turquoise are likely chrysocolla. How to recognize it Softer, more powdery blue‑green Often mixed with quartz, malachite, or copper minerals Can look like watercolor patterns What it is
A hydrated copper silicate that often forms alongside turquoise and malachite.
It’s softer, so it’s often stabilized or found in mixed matrix pieces.Turquoise
