Quartz (''Mango Quartz'')

Item Description

A very showy display piece of these unique and attractive Quartz specimens that first appeared on the market in 2017. Due to their wonderfully singular color, along with excellent crystallization, they were very well-received, and instantly regarded as some of the most distinctive Quartz crystals ever found. This distinguishing soft yellow-orange color has given these Quartz crystals the nickname "Mango Quartz", and have become very popular among Quartz collectors and crystal enthusiasts. Typically, Colombia isn't a big Quartz crystal producing country, and these crystals were actually mined along a roadcut in the middle of the famous Emerald mining region in Boyacá. The upper portions of most of these crystals feature bright yellow-orange inclusions of a mineral that was first reported to be Humboltine, but others have since stated it is Halloysite. I cannot find definitive confirmation that the inclusions are Halloysite, only referential posts on various sites online. The Quartz crystals are high quality in their own right, as they are textbook, hexagonal prisms with good luster, sharpness and fine internal gemminess, which is only accentuated by the beautiful inclusions. This piece is a lovely crystal group featuring a predominant crystal with sharp, lustrous faces and of course those eye-catching yellow inclusions, sitting atop thinner additional prisms of Quartz on matrix. The tip of the main crystal is nicked, and some of the secondary Quartz crystals are broken, but it still sits nicely on its own and displays well as you can see. I don't know if there will be more of these in the future, so if you're a fan of interesting Quartz specimens or unique inclusion specimens, don't pass this one up, as there are not nearly as many as there were a few years ago.
