Prehnite is a semi-translucent mint green gemstone with dark grey inclusions. Geologically, Prehnite is a igneous rock consisting mostly of calcium and aluminium minerals.

In jewelry design, Prehnite coordinates with both gold and silver metals. Prehnite matches well with Clear Quartz and Tourmaline, Strawberry Quartz, Rainbow Phantom Quartz, and Jade.

Prehnite is named for Dutch colonist Hendrik Von Prehn, who first discovered and indexed this gemstone in Cape of Good Hope, South Africa in the 1780s. Today, this stone is most often sourced from South Africa, Namibia, and Australia. Metaphysically, Prehnite is thought to enhance calmness during meditation or visualization practices. Prehnite is also believed to hold healing properties that support people reaching their best selves and building resilience against negativity.
