Geological History

This beautiful Rhodolite was formed several hundred million years ago in a pegmatitic vein in Tanzania, East Africa. Heated ground waters circulated through rock fractures, dissolving minerals from the surrounding rocks and redepositing them in open spaces like fractures. Amongst these chemicals was one very important component iron. It is this which makes Rhodolite red. It is an impurity that was formed within the garnet crystal and without it the gem would have had no colour. As the rock folded with time, the heat and pressure grew to a level where it was possible for this Rhodolite crystal to form. This remained constant for the many millions of years between that time and the time it was discovered by man. Hundreds of millions of years later this garnet crystal was chiseled from the crevice within which it had lain for so long and carried to the surface by miners in the Kangala area of Tanzania, in East Africa. From there it found its way to Nairobi where it was presented in the offices of Lapigems Gem Company. It was identified as a fine Rhodolite Garnet and cut by Lapigems master cutters into what you see today. A journey of 550 million years has paused here.
