Quartz (''Mango Quartz'')

Item Description

We first saw these specimens appears on the market in 2017, and they made a big splash as they were instantly regarded as some of the most unique Quartz crystals ever found. Most people don't think of Colombia as a big Quartz producing country, and these crystals are 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 supreme colorless OPTIC clarity, which is only accentuated by the beautiful inclusions. This piece is a lovely crystal group with sharp, lustrous faces and of course those eye-catching yellow inclusions. This distinctive color has given these Quartz crystals the nickname "Mango Quartz", and have become very popular among Quartz collectors and crystal enthusiasts. 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.
