A stunning cluster of bright blue Lazurite Crystals on Calcite with Pyrite. Or, in other words, deconstructed Lapis Lazuli! One extra large crystal dominates the specimen, with at least 10 other partial crystals visible in the cluster. This is a very collectible piece and a beautiful example of Afghanistan’s rich mineral wealth. Great colour splash for the collection. This specimen stands well on two sides to show off the big crystal of Lazurite.

Lazurite is the blue component of the ‘gemstone’ (or, more accurately, decorative rock) Lapis Lazuli, which is a Lazurite-Calcite-Pyrite rock. Lazurite is a popular but generally expensive mineral. Well-formed, deep blue crystals are rare and valuable. It is more commonly found massive and combined with other minerals into a rock called lapis lazuli.
