AI-assisted summary
Description from the seller
Rough ruby in combination with tourmaline crystals weighing 47.83 grams corresponding to 239.15 ct.
It has a hexagonal shape due to its crystallization in the trigonal system, forming structures in hexagonal prisms.
Its natural formation occurs under extreme geological conditions in igneous and metamorphic processes.
The ruby belongs to the corundum family. It is one of the hardest and most durable gemstones, reaching 9 on the Mohs scale. Its name comes from the Latin "ruber" meaning "red". This characteristic red color comes from chromium, which appears as an impurity in the chemical composition of corundum (aluminum oxide). Chromium, furthermore, is responsible for the ruby’s fluorescence under ultraviolet light.
Tourmaline is a complex boron-aluminum silicate with a hardness of 7–7.5 on the Mohs scale. They appear as black prismatic crystals associated with the ruby.
The joint formation of these two very different minerals is due to very specific pressure and temperature conditions, such as those in contact metamorphic rocks or in complex pegmatites.
The ruby is associated with vitality, courage, and passion. It is considered a fire stone that energizes the body and mind, protecting against negative energies. All this, together with the protective and healing power of tourmaline, makes this jewel a powerful amulet against negative energies.
An exclusive gem for any mineral enthusiast.
