PRODUCT INFORMATION

General Description

Blue Calcite from Madagascar has variable colour intensity from light blue to gemmy intense blue. The material can have complex patterns or an internal cracked like pattern. Material is graded according to intensity and consistency of the colour as well as the solidity of the piece itself (i.e. no cracking, etc). Each piece is hand selected and beautifully polished .

Septarian Nodule, affectionately known as Dragon Eggs, is a tri-colour concretion comprised of Aragonite (brown), Calcite (yellow), and Limestone (grey). The name "Septarian" originates from the word "Septaria," typically associated with concretions that exhibit internal cavities or cracks. This extraordinary mineral traces its origins back 50 to 70 million years ago, during Earth's Cretaceous Period, in a fascinating geological tale. At that time, an abundance of marine life was irresistibly drawn to the molten sediment produced by massive volcanic eruptions. As these prehistoric sea creatures perished, their chemical composition became integrated into the surrounding sedimentary rock, gradually forming the unique nodules we admire today. As global oceans receded, the water contained within these concretions evaporated, giving rise to extensive internal cracks. Over time, the chemicals within the remnants of these ancient sea creatures crystallized, forming distinctive Aragonite "crusts" and drusy Calcite crystals, a process that accounts for the striking patterns found within Septarian Nodules. Most Septarian Nodules originate from regions such as Utah or Madagascar, which experienced similar geological conditions during that ancient period.
