This is a sparkling association of pink-orange stilbite crystals and quartz crystals. The stilbite formed as radiating fan-like crystals within the mass of both small and druzy quartz crystals. It's very possible that there is an association of apophyllite crystals, however the quartz crystals are easily identifiable in this cluster.
Stilbite is probably the most common zeolite found in these deposits. Crystals often form flowery, bowtie or hourglass shaped structures and come in a variety of colors. Some of the most beautiful colorations are the pink or peach tints.
Silicon Dioxide, also know as SiO2 or Quartz, is the second most abundant mineral in the Earth's crust. Quartz crystals generally grow in silica-rich, hot watery solutions called hydrothermal environments, at temperatures between 100°C and 450°C, and usually under very high pressure. Quartz veins are formed when open fissures are filled with hot water during the closing stages of mountains forming, and can be hundreds of millions of years old.
