Prehnite (polished nodule)

Item Description

This is a delightful and colorful polished Prehnite nodule from the Wave Hill cattle station locality in the Northern Territory, Australia. This locality can be found about 30 km (19 miles) east of the town of Kalkaringi. This locality is best known for its Prehnites, but they are rarely seen in crystallized specimens, rather rounded nodules that weather out of basalt. These nodules have virtually no specimen value, as they are an unassuming reddish-brown hue on the exterior, but when they are sliced and polished, they reveal some of the best color and quality Prehnite you'll find from anywhere. The enticing green hues seen in this material, combined with the above average gemminess makes for some very eye-catching pieces. This piece is an attractive example of this classic material, as it has a very pleasing glowing green hue, with good internal translucency and some attractive "wispy" inclusions creating an almost ethereal appearance. A really cool piece for any fan of worldwide Prehnites or lapidary grade specimens. You don't see many of these on the market, so don't miss out. Specimen weight is 149.1 grams.
