Specimens from Russia are uncommon in the US, mostly thanks to Russia’s strict export laws regsrding minerals as national treasures. However, there are a few legal ways these pieces find their way into the market. Growth Interference Quartz (GIQ) is an occurrence where Quartz and Calcite compete for space in solution. The calcite changes the habit of the quartz by interfering with the normal quartz growth. When the calcite is then etched away with acid, the results are some fantastic and wild shapes and habits of Quartz!! In 2007 we bought the largest existing lot of Bor Quarry Quartz with Growth Interference from Dalnegorsk. This is a fine small cabinet example with distinguishing aesthetics, and an uncommon provenance to hold its worth for years to come.
