The Septarian Nodule beads were formed between 50 to 70 million years ago. As a result of volcanic eruptions, dead sea life was chemically attracted to the sediment around them, forming mud balls. As the ocean receded, the balls dried and cracked. Due to their bentonite content they also shrank in size, creating the cracks inside. As decomposed shells seeped down into the cracks in the mud balls, calcite crystals formed. The outer thin walls of calcite then transformed into aragonite.
The name Septarian comes from the Latin word "septem", meaning seven, because the mud balls had a tendency to crack in 7 points in every direction, thereby creating the distinctive pattern these nodules exhibit. Septarians are composed of Calcite (The Yellow Centres), Aragonite (The Brown Lines), and the outer grey rock is Limestone.
Chrysoberyl is the third hardest mineral on the Mohs scale of hardness. Ordinary chrysoberyl is yellowish-green and transparent to translucent. When the mineral exhibits good pale green to yellow color and is transparent, then it is used as a gemstone. There are three main varieties of Chrysoberyl: ordinary yellow-to-green Chrysoberyl (which was referred to as "chrysolite" during the Victorian and Edwardian eras), Cat's Eye or Cymophane, and Alexandrite...
Top quality Alexandrite is very rare and hardly ever used in modern jewellery. In antique Russian jewellery you may come across it with a little luck, since Russian master jewellers loved this stone. It was named after Russian tsar Alexander II (1818-1881), the very first crystals having been discovered in April 1834 in the emerald mines near the Tokovaya River in the Urals. The discovery was made on the day the future tsar came of age. Although alexandrite is a relatively young gemstone, it certainly has a noble history. Since it shows both red and green, the principal colours of old Imperial Russia, it inevitably became the national stone of tsarist Russia.
Diamond has many unequaled qualities and is very unique among minerals.
It is the hardest known substance being a 10 on the Mohs scale, and is 40 times harder than Corundum, which is number 9 on the Mohs scale.
It is the greatest conductor of heat, it has the highest melting point of any substance (7362° F/4090° C). Because of heat conduction, Diamonds are cold to the feel at or below room temperature. When heated, a Diamond will remain hot long after the heat source is removed.
A Diamond has the highest refractive index of any natural mineral. It also has the most dense atomical configuration of any mineral, and is transparent over the greatest number of wavelengths.
Sodalite is a dark blue stone with interspersed white calcite. It is sometimes confused with lapis lazuli as it also has small specks of pyrite in it. The largest deposit of sodalite is in Brazil.
Sodalite is said to bring inner peace. Keep sodalite in your pockets and in every room of your house, so its peaceful properties will flow all around you.
Sodalite folklore suggests that it is the stone of athletics, as it stimulates endurance. It is said sodalite will harmonise the inner being or the conscious and subconscious mind. Sodalite promotes peace and harmony. Sodalite is extra lucky for writers.
