Thenardite
A specimen of the mineral Thenardite (number 1929, 1859) held in the Natural History Museums Mineral Department

Birthstone Series: Lazurite

Gypsum is comprised of (hydrated calcium sulphate). It forms from the evaporation of highly saline waters producing massive beds

Cerussite
Aggregates of white crystals on globular crystalline baryte. Cerussite comprises of (lead carbonate). Specimen from Frank Mills mine, Christow, Devon

Gypsum crystals - A desert rose
Gypsum is comprised of (hydrated calcium sulphate). It forms from the evaporation of highly saline waters producing this ornate arrangement of crystals

Connellite
Deep-blue velvety crust of needles with some red cuprite. Connellite comprises of (hydrated copper sulphate chloride hydroxide). Specimen from Wheal Muttrell, Gwennap, Cornwall

Celestite

"Sulfate: A Journey through Geological Wonders and Natural Phenomena" Plate 1 from Histoire naturelle? (1789) unveils the captivating world of sulfates, showcasing their mesmerizing formations. Linarite, with its vibrant blue hues, captures our attention as we delve into the diverse mineral kingdom. Anglesite, discovered in Matlock, Derbyshire, England, showcases its translucent beauty. This sulfate crystal is a testament to the Earth's ability to create stunning geological wonders that leave us in awe. Baryte from Bonsall Dale in Derbyshire enchants us with its delicate structure and shimmering appearance. Its presence reminds us of the intricate processes that shape our planet over millions of years. Gypsum found in Cumberland Mine at Matlock Bath reveals itself as an ethereal masterpiece. The interplay between light and shadow on this sulfate specimen evokes a sense of tranquility and harmony within nature's creations. As we travel further north to Iceland's Reykjahlid region during summer or winter, we encounter breathtaking landscapes along the road to Myvatn. These picturesque scenes showcase sulfur-rich geothermal areas like Hverir and Krafla craters—reminders of how sulfates contribute to Iceland's unique volcanic activity. The Productions of the Solfaterra depicted on plate 9 from Campi Phlegraei transport us back in time to Naples' volcanic region. Witnessing these sulfurous emissions firsthand would have been both thrilling and humbling—a reminder of Earth's raw power beneath our feet. Sulfate minerals continue to captivate scientists and enthusiasts alike with their remarkable diversity and aesthetic appeal. From ancient history documented by Histoire naturelle? (1789) to present-day discoveries across various locations worldwide—such as those captured by EyeUbiquitous_20104754 & EyeUbiquitous_20104753—the allure of sulfates remains ever-present.
