Real Aragonite Crystal Cluster 3-4″ Large Crystal Specimen

• Aragonite is the main component of many organic substances, such as pearl and coral. The iridescent surface of Pearl and mother-of-pearl is actually a layer of Aragonite secreted by mollusks and related invertebrates • Most large Aragonite crystals are twinned growths of three individual crystals that form pseudohexagonal trillings. Aragonite crystallizes in the orthorhombic system (crystals that have three axes that are all unequal in length and 90° to each other), but because of these twinned growths most prismatic [...]

Aragonite Crystal Cluster 2-3″ Hexagonal Crystal Specimen

• Aragonite forms orthorhombic crystals which have three axes of different lengths intersecting at right angles • Although Aragonite crystallizes in the orthorhombic system, virtually all its crystals are hexagonal shaped • It forms by biological and physical processes, including precipitation from marine and freshwater environments • These are real mineral specimens, variations in size, shape, and color as well as minor imperfections should be expected • This listing is for one aragonite mineral similar to reference specimens

Mini Septarian Dragon’s Egg Palmstone | Calcite Aragonite 1.5-2″ Smooth Limestone Rock | 1 piece

• Septarian Dragon Eggs, also known as Septarian nodules, were formed around 50 to 70 million years ago as a result of volcanic eruptions. Dead sea life was chemically attracted to the sediment around it forming mud balls which, when the ocean receded, dried up. Due to their bentonite content they also shrank in size, creating the cracks inside • They are composed of Calcite, which makes up the yellow portion, aragonite which make up the brown lines, and limestone [...]
