This Chocolate Window Quartz was mined in 2003 in China. Chocolate Window Quartz is a creative name given to this odd variety of Quartz from China originally found in 2005. It came out for a few years, and then disappeared. It is characterized by long milky white coated Quartz covered by a secondary growth that is clear and glassy, and has a natural irradiation that occurred around the edges. This clear secondary face gives a "window" to view inside the Quartz, where the first growth did not. Strange stuff! There were quite a few very attractive clusters and long singles, but the majority of this material has evaporated into the market.
Around 2007 we bought the largest existing lot of Bor Quarry Quartz with Growth Interference from Dalnegorsk. Here you will find a full spectrum of Growth Interference Quartz (GIQ) plus other oddball Quartzes from Bor.
Quartz was our first stone passion. For a decade we have attempted to gather as much diversely included and colorful Quartzes as we could find, from every corner of the globe, travelling both to country of origin, and utilizing a vast network of suppliers developed through exhibiting at major USA and international gem and mineral shows. Here is a representation of those efforts - some of the best of our finds, as well as a tremendous volume that has just piled up as a result of wholesaling in volume! If you have a variety of aesthetic Quartz to add to our offerings, we'd love to see a flat of material! We also personally collect high quality fine Quartzes.
The Chinese mineral industry produces a tremendous array of specimens from many different regions in its vast country. One common thing we have found is that most Chinese minerals specimens that surface in worldwide markets tend to "come and go". Some mines produce similar specimens for years, but many localities produce something for a few years, and then it is finished, and something else comes up. Its similar worldwide, but more profound in China. We cannot think of Chinese minerals without first thinking of Fluorite. China has the greatest array of Fluorites of any country. What China lacks in pegmatite minerals, it makes up for in the prolific new sulfide deposits of Inner Mongolia. One thing is for sure about China... when it produces, it usually produces in quantity!
