A wire-wrapped prehnite gemstone dangles about an inch below a tiny moonstone and 18" gold-filled rope chain. This lariat necklace is light and oh-so-pretty.
What is Prehnite?
Prehnite is a translucent to transparent gem. It was the first mineral to be named after an individual, and it was also the first mineral to be described from South Africa, long before South Africa became one of the most important sources for precious and semi-precious gems. It was first described in 1788 after it was discovered in the Karoo dolerites of Cradock, South Africa. Prehnite was later named after its discoverer, Colonel Hendrik von Prehn (1733-1785), a Dutch mineralogist and an early governor of the Cape of Good Hope colony. Until recently, prehnite was a rare collector's gemstone, but new deposits have now made it more readily available.
What is Moonstone?
Named for its glowing color sheen that resembles the moonlight, Moonstone displays a unique play of color. The effect is in the form of a moving floating light or sheen that is caused by structural anomalies within the crystal formation.
