It typically has a dark gray to black host rock (basalt) filled with small, colorful mineral \"bubbles\" (amygdules) that resemble stars or swirling galaxies. \n\nKey Characteristics\nHost Rock: Usually a dense, dark basalt, but it can also be found in reddish-brown rhyolite.\nThe \"Stars\" (Inclusions): These are gas bubbles (vesicles) from ancient lava flows that were later filled with secondary minerals such as:\nNative Copper: Gives the stone a metallic sparkle.\nQuartz and Agate: Often white, clear, or banded.\nEpidote and Chlorite: Provide green tones.\nPrehnite or Feldspar: Can appear as pink or white spots.\nOther \"Galaxy\" Rocks: Some collectors also use the term to describe Yooperlites (syenite rich in fluorescent sodalite) because their glow under UV light resembles a star field.","brand":"Earth's Sparkles","offers":[{"title":"Default Title","offer_id":48007870316765,"sku":null,"price":30.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0834\/5115\/0557\/files\/2c797e0f-il_fullxfull.7857610496_ledo.jpg?v=1780935600","url":"https:\/\/earthssparkles.com\/products\/galaxy-stone-bracelet","provider":"Earth's Sparkles","version":"1.0","type":"link"}
