Danburite is a calcium boron silicate mineral with a chemical formula of CaB₂(SiO₄)₂. It has a hardness of 7 to 7.5 and a specific gravity of 3.0. The mineral has an orthorhombic crystal form. It is usually colorless, like Quartz, but can also be either pale yellow or yellowish-brown. This is the first time we see this bright yellow color perfectly crystallized with multiple Danburite crystals with Tourmaline and Quartz from Afghanistan. All crystals are completely fine with crazy luster and double terminated, with razor-sharp termination, superb bright yellow color with super luster the faces are sharp and with great color, and the Tourmy has also stunning colors with good transparency! 

To add something sweet to this rare find is this incredible well-terminated Tourmaline growth in the back of the Danburite crystals with Quartz is breathtaking. Tourmaline crystal is perfect, the whole specimen is totally floater without any damage! This locality is famous for new find minerals such as Caesium Beryl and Phenakite in past but this time it was a great surprise to find this colorful mineral and to have the Tourmaline grown on it makes it unique and very special in my humble opinion, such a specie in such combination has never been owned or seen by anyone before from Afghanistan or Pakistan. A Super sweet cabinet small and a great piece to add to any collection, especially a cabinet-size collection!
