Delve into the Top 10 Rare Agates

# # Deep Drill 10 Ultimate Rare Agave: Mineralogical Value and Gemstone Science of Deposition

In mineralogy and gemology, the "Agate" is classified as a Cryptocrystalline Quartz, also known as the Chalcedony Group, with a chemical formula of SiO2. The highlight that distinguishes the agate from the common Chalcedony is the "Banding" caused by the precipitation of silica solutions in volcanic rock cavities with changing temperature and pressure over time. However, the step up to "the level of agate needed by collectors" is more intricate than just the pattern.
