Amethyst

Amethyst Cathedrals from Brazil. 

£15-£570 depending on size.

A stunning Centre Piece!

Amethyst is a violet variety of quartz. The name comes from Greek Amethystos (a = not, and metho = intoxicate), a reference to the belief that the stone protected its owner from Drunkenness.

These are always a firm favourite.

We have ones brightening up old fire places in our home.

Ammonites

Ammonite halves from Madagascar - £35-£45 for each half.

The Fibonacci Fossil

 

These Cleoniceras ammonites are between 65 and 135 million years old (Cretaceous). The sutured chambers are filled with minerals ranging from Calcite to Quartz and Jaspers.

Interesting fact is the ammonites are called the Fibonacci fossil, because their chambers grow to a mathematical ratio and are a natural occurring example of the Fibonacci sequence, where you add the previous two numbers to get the next one : 0, 1, 1, 2, 3, 5, 8, 13, 21, 34 etc.

I've seen one of these for sale in a UK fossil store for £692. Ours is a bargain!

Megalodon

Megalodon teeth, polished or raw - £40-£265 each

Coming Soon! Unfortunately not in the October sale due to delivery issue

Megalodon, means “big tooth” and is an extinct species of shark that lived approximately 23 to 3.6 million years ago, during the Early Miocene to Pliocene. It was formerly thought to be a close relative of the great white shark, but then the Megalodon is twice the size.

 

These teeth are found by divers in the mud of South Carolina. Must arrange a diving trip!!

 

These must put the biggest smile and wonder on the faces of your children, grandchildren, nieces and nephews. I remember the first time I saw one.

Stone Bowls

Variety of mineral and petrified wooden stone bowls from Madagascar - £29-£350

Great Ornaments

 

Bowls are beautifully polished and are made from Kambaba Jasper, petrified wood, quartz, rose quartz, blue calcite and feldspar.

Many minerals are believed to have spiritual qualities. Rose quartz creates a sense of calmness, blue calcite aids emotional healing.

Kambaba Jasper is a green stromatolite, a Cyanobacteria, which helped create the first oxygen in the atmosphere. This stone is approximately 3 billion years old.

A gorgeous accessory for the house or office.

GEODES

Amethyst and Citrine Crusts on stands from Brazil £50 - £900

Collectors be quick!

Amethyst is formed inside igneous volcanic rocks called basalts, which are created by volcanic lava. When cavities are filled with a silica rich liquid, the well known purple crystals (due to trace amounts of iron) begin to form.

 

Most Citrine is formed by heat treating purple Amethyst.

These crusts have spectacular crystals and deep colouration to make a beautiful statement in any home

Agate Geodes from Brazil

£33-£65 each

Great Gifts!

Agate is quartz with impurities causing many different patterns. Most agates occur in the cavaties of eruptive rocks or ancient lavas forming geodes filled with quartz..

 

These pieces from Brazil are beautifully displayed on a stand and would make a great gift for a speaker at a conference or for friends and family at Christmas.

Fluorite is the mineral form of Calcium fluoride, CaF2. Is crystalizes in isometric cubic habitat, although octahedral and more complex isometric forms are not uncommon.

Polished Labradorite from Madagascar

Magical

Labradorite is a feldspar mineral, which can display an iridescent effect.It is treasured for its remarkable play of colour known as labradorescence.

 

It was first identified in Labrador, Canada and hence the name. Folklore of the Inuit people claims it fell from the frozen fire of the Aurora Borealis, an ordinary stone that similarly transforms to a shimmering mystical light.
