Raw acicular malachite, a cluster of fine needle-like crystals grown in radiating fan-shaped sprays from multiple growth centers. The crystal tips catch light like tiny mirrors and produce a sparkling, almost metallic shimmer that polished malachite cannot replicate. Lit crystals glow a bright emerald green, while the shaded areas between the fans sink to deep forest green and nearly black. Dark grey-black host rock, likely limonite and typical of Congolese material, is visible between the crystal clusters. The overall form is three-dimensional and irregular, several separate sprays grouped into a composite aggregate measuring 37x29mm.
Acicular malachite is far less commonly seen than the banded botryoidal material used for cabochons. This habit shows the mineral as it actually forms in nature, in delicate needle sprays rather than rounded layered masses. The Democratic Republic of Congo is the world's primary source for fine malachite specimens of all habits. At 22g the piece is substantial enough for a mineral collection or for desk and shelf display.

About malachite
Malachite is a copper carbonate whose bands of green grow in layers, much like agate. At 3.5 to 4 on the Mohs scale it is soft and scratches easily.
Cleaning
Do not wash it. Dust it with a soft, dry brush or an air blower, and keep it dry. Skip ultrasonic and steam cleaners: malachite is soft and porous. Keep it away from acids, even lemon juice and vinegar, and household cleaners, which etch it.
Wear and storage
Store it padded and apart from other specimens, so its edges and faces do not chip or scratch. Lift it by its base or matrix, not by the crystals. It is softer than a steel knife, so keep metal tools and harder stones away from it.
