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.
Charoite is unusual with strange looking spirally strands of fibrous material and chatoyancy and is named after the Charo River near where it is found in the Murun Mountains, Yakutia, Russia. This the only known location for this rare mineral.
The colours range from bright lavender, violet and lilac to dark purple with swirling patterns of black Augite, transparent crystals of microcline feldspar, and/or orange Tinaksite.
Charoite is beleived to be an incredible stone of the Violet Ray with an almost tangible movement of energy flowing in magnificent swirls and eddies of violet, lavender and purple. It is rare and complex, one of nature’s best dream stones and illuminators, allowing access to lessons learned in past lives, healing emotional fears to live in the present, and opening to spiritual guidance for the future.
Jet is not actually a stone but the fossilised remains of the water logged monkey puzzle tree. It is 3-4 on the Mohs scale. It is said that Jet can be used for removal of negative energies of any kind, including negative thoughts and fears, and for protection against illness or violence. This particular Jet came from an archeological dig the Middle East some 80 years ago.
