{"product_id":"calcite-butterfly-twins","title":"CALCITE BUTTERFLY TWINS","description":"Beautiful butterfly twinned crystals of Calcite are delightfully scattered over a sparkling creamy druse of Dolomite with associated well-formed prismatic Quartz crystals.  From Ametista do Sul in the Alto Uruguai region of Rio Grande do Sul, Brazil, the colourless Calcite crystals are gemmy to translucent with a strong tinge of milky white.  Butterfly twins are richly distributed all over the display surface, averaging around 2.1 cm across.  If this were my specimen I would tend to call these 'heart' twins, but 'butterfly' is what they named at Ametista do Sul.  Elegant single prismatic Quartz crystals to over 1 cm tall are richly scattered between the Calcite twins and are of a similar colourless to milky white to that of the Calcite.  By contrast, the carpet of micro-crystallised buttermilk cream Dolomite crystals forms a good contrast to the display crystals.  A fine specimen showing off many fine examples of twinning.","brand":"Crystal Classics","offers":[{"title":"Default Title","offer_id":46540865634479,"sku":"CC6697","price":4500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/8516\/2671\/files\/CC6697.png?v=1770208633","url":"https:\/\/crystalclassics.com\/products\/calcite-butterfly-twins","provider":"Crystal Classics","version":"1.0","type":"link"}
