Datolites from Dal'negorsk are among some of the finest quality Datolites in the world, not to mention large and colorful. This piece came out of Dal'negorsk about 10 years ago, and is simply a unique and attractive specimen of this material. It features large, sharp, highly lustrous (in areas), gemmy green blocky crystals of Datolite with associated stubby Smoky Quartz crystals which are coating much of the Datolite crystals. The Datolites themselves have some very interesting parallel etching patterns throughout the crystals, giving it a very one-of-a-kind appearance. The largest Datolite crystal measures 8.2 cm across, which is very good sized for this locality. Ex. Richard Kosnar Collection.
