Dangerous Plants

The English Yew is native to Europe, Northern Africa and South West Asia. It is a small to medium tree that has seeds enclosed in a soft, red, berry like armor. The berry armor is the only part of the fruit that is not poisonous and this allows birds to eat the fruit and spread the seeds without ill effect. It takes a dose of about 50g to be fatal to a human.

Symptoms include difficulty breathing, muscle tremors, convulsion, collapse and finally cardiac arrest. In cases of severe poisoning, death can occur so fast that the other symptoms are missed.
Water hemlock, or poison parsnip, is a group of highly poisonous plants that is native to the temperate regions of the northern hemisphere. The plants all have very distinctive small white or green flowers, arranged in an umbrella shape. Water hemlock is considered to be North America’s most poisonous plant as it is incredibly poisonous to humans. The plants contain a toxin named cicutoxin which causes seizures.

This poison is found in all parts of the plant but is most concentrated in the roots, which is most potent in the spring. Besides the almost immediate seizures, other symptoms include nausea, vomiting, abdominal pains, tremors and confusion. Death is usually caused by respiratory failure or ventricular fibrillation and can occur just a few hours after ingestion.
Wolfsbane, also known as leopard’s bane, or devils helmet, is a plant belonging to the buttercup family. These perennial plants are native to mountainous regions of the northern hemisphere. The plant contains very large quantities of a poison called alkaloid pseudaconitine. In cases of ingestion, symptoms include burning in the limbs and abdomen and sets in immediately.

In cases of large doses, death can occur within 2-6 hours and 20ml is enough to kill an adult human.

Wolfsbane is mentioned in mythology and werewolf lore as being able to either repel the werewolves/lycanthropes, or to induce the wolf state regardless of the moon phase. Hence the name.
The Rosary Pea, also known as Crab’s eye or Jumbie bead, is a slender perennial climber that twines around trees, shrubs and hedges. The plant is native to Indonesia, but grows in most parts of the world. It is best known for its seeds, which are used as beads, and have a bright red to arrange color with a single black spot.

The poison contained in the plant (abrin) is very similar to the poison ricin, found in some other poisonous plants. There is one main difference between these poisons, and that is that abrin is about 75 times stronger than ricin. This concludes that the lethal dose is much less, and in some cases as little as 3 micrograms can kill an adult human.
Belladonna, also known as Devils berries, death cherries or deadly nightshade, is native to Europe, North Africa and Western Asia. It is also one of the world’s most poisonous plants as it contains Tropane alkaloids, some of which cause delirium and hallucinations. Other symptoms of Belladonna poisoning include loss of voice, dry mouth, headaches, breathing difficulty and convulsions.

The whole plant is poisonous, but berries usually play the greatest risk, as they are sweet and tend to attract children. 10 – 20 berries can kill an adult, but it only takes 1 leaf (in which the poisons are much more concentrated) to kill an adult man.
Castor plants are indigenous to the Mediterranean basin, eastern Africa and India, but are widely grown as an ornamental plant. A toxin called ricin is found throughout the plant, but is concentrated in the seeds/beans (which castor oil is made from). One raw seed is enough to kill a human in 2 days, which makes for a long, agonizing and unstoppable death. The first symptoms will be experienced within a few hours and will include a burning sensation in the throat & mouth, abdominal pain, bloody diarrhea and vomiting. The process is unstoppable and the final cause of death will be dehydration.

Strangely, humans are the most sensitive to these seeds, as it takes 1-4 to kill a full grown human, 11 to kill a dog and a whopping 80 seeds to kill a duck. The castor plant currently holds the Guinness World Record for most poisonous plant.

US Gemstones

Arizona is the top gem producer in the United States. Arizona is a producer of turquoise, peridot and petrified wood. Gemstones like azurite, chrysocolla and malachite are associated with Arizona's copper deposits. Agate, amethyst, garnet, jade, jasper, obsidian, onyx, and opal have all been found in Arizona.
Rubies, sapphires and emeralds can be found in North Carolina although not concentrated enough to support a large gemstone industry.

Gem materials in North Carolina include aquamarine, beryl, citrine, emerald, garnet, moonstone, rose quartz, ruby, sapphire, smokey quartz, staurolite, topaz, and tourmaline.
Oregon produces some of the best feldspars in the world. Small mining operations have become famous for producing "Oregon Sunstone," a transparent feldspar that contains tiny copper platelets aligned in a common orientation. As a sunstone is tilted in the light, these platelets simultaneously reflect a flash of light.

Oregon produces other gem materials including the famous "thunderegg" a geode that is ugly on the outside but often filled with chalcedonly, opal or crystals that can be cut into gemstones.
Utah produces a wide variety of gemstones. Amethyst, garnet, jasper, agate and opals are found at numerous locations in Utah.

Although topaz is Utah's state gemstone, the gemstone that is getting a lot of attention is the very rare red beryl, also known as bixbyite.
California is widely known for its tourmaline and turquoise production. Native Americans were the first to treasure these minerals, and a commercial gemstone industry was active by the late 1800s. The tourmaline deposits of Riverdale and San Diego Counties have supplied more tourmaline for cutting and mineral specimens than any other tourmaline deposits in the northern hemisphere.

California gemstones also include many varieties of agate, jasper, jade, garnet and quartz. The state is one of the world's only sources of benitoite, a blue barium titanium silicate, and it has been named the state gemstone.
Montana's most popular gemstone product is sapphire. Yogo Gulch sapphires have been famous for over 100 years, and the production of sapphire continues today. Sapphires are produced from both rock and alluvial deposits. They occur in a wide range of colors which include blue, blue-green, green, pink, pale red, purple, yellow, and orange.

Many parts of Montana boast agate and jasper. One of the most popular is 'Montana Moss Agate'

Gold Rush in Rajasthan

An abandoned stone quarry in Rajasthan’s Tonk district has become the destination of thousands of villagers from far and wide. Locals reported finding 4th and 5th century gold coins, prompting the police to clamp prohibitory orders and mount a round-the-clock vigil at the site.
After two coins were recovered from a jeweller on December 7, the police contacted the Archaeological Survey of India, which sent two archaeologists to determine the value of the coins. Their finding was that the coins were both genuine and priceless. “Two types of coins belonging to the times of Samudragupta (335-380AD) and Kumaragupta I (414-485 AD) have been found."

Police believe the villagers have taken away nearly 2,000 coins from the quarry. Police now stand guard and surrounding villages have been raided, recovering nine coins.
