Outstanding, sharp cluster of blue Prehnite, with large individual crystals. Crystallized Prehnite is uncommon worldwide with most Prehnite found as botryoidal masses. The best crystals are known from the Jeffrey Mine in Canada and here at Merelani. Merelani Prehnite is mostly yellow with these blue Prehnites being much less common and blues of this quality with such good crystal form even more so. These are also color change, producing different shades of blue in indoor versus outdoor lighting.
