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.
Tanzanite was first discovered in Tanzania, East Africa and is part of the Zoisite mineral species and is only found in East Africa.
Legend says it was Masai cattle herders that first noticed Tanzanite some 30 years ago after a fire caused by lightening burned areas in Tanzania. The herders noticed that brown zoiscite crystals had turned a deep blue-purple due to the heat from the fire.
While Tanzanite is often a blue colour when first mined it is very rarely a pure blue and usually exhibits rich purple overtones. It can also be brown and is routinely heat treated to permanently draw out its exotic bluish-purple colour.
Lemon Quartz (also called green gold) is a beautiful variety of yellow quartz with shades of green that is mined in Brazil. Like Citrine, Lemon quartz is created when Amethyst is heated at extremely high temperatures. What differs is the presences iron. This heating process with iron is what gives lemon quartz its brilliant, yellow colour...
Yellow as a colour energy signifies creativity, organisation, optimism and well-being. Meditation with lemon quartz is said to enhance your focus on your goals with a clear and bright outlook to make your future the way you want it to be!
