larimar is one of the newest and rarest gem stone . It was formed million of years ago by volcanic activity and occurs now in just one sq. kilometer of a remote mountain range on the island of Hispaniola in dominican republic. The extra ordinary colour of the stone comes from the unique composition of the minerals including copper and vanadium The name LARIMAR was orginated by Miguel Mendez who named the gem after her daughter ‘LARIssa’ and ‘MAR’,the Spanish word for the sea, together. This is also known as Dolphin stone. LARIMAR is a powerful throat chakra stone. LARIMAR helps women who wear it to awaken the divine feminine within .
Pietersite Also known as Tempeststone in the Pagan community, was discovered by Sid Pieters in 1962 while he was prospecting some farmland in Namibia, Africa. the material was named pietersite. Currently there are only two known sources of pietersite; China and Africa. These two forms of pietersite are similar but still somewhat different from each other. The Chinese pietersite''s fibrous mineral is a magnesium-rich alkalic amphibole. The African (Namibian) variety is mainly crocidolite.
In order to best bring out the play of color in a Fine Opal, the stones are cut and polished to round or oval cabochons, or any other softly domed shape, depending on the raw material. Only the best qualities of Fire Opal, however, are suited to faceting.
Opal is often found as flat lenses, or thin layers, bigger pieces are rather rare. If you leave a thin but supporting layer of the harder mother rock, you will receive a pre-stage of the Opal-doublets which are frequently used today for mass produced jewellery. These are gemstone combinations consisting of a surface from millimeter-thin Opal plates, which have been mounted on Onyx, Obsidian, artificial black glass, or Potch-Opal.
Triplets have been developed from this design; here the Opal layer receives an additional cover from Rock Crystal, Plastic, Hard Glass or Lead Glass for protection.
Black Opal or Opal with a dark grey body shows the most brilliant play of colors imaginable.Crystal opal, which comes immediately after Black Opal in the hit list, should be more transparent with a deep play of colors. White or milky Opals show more diffuse colors and are the least expensive Opals.
The most important criterion for determining the price of an Opal, however, is the play of color, the colors as such and their pattern. If the color red appears when looking through the stone, all the other colors will appear also. For evaluating Opals the thickness of the Opal layer is considered, the beauty of the patterning, the cut, weight and finish. Finally the total impression will be decisive, and of course offer and demand will determine ho much you will have to pay for “your” Opal. If you are interested in a really valuable specimen, get an Opal expert to advise you, because it takes a real expert to know about the many criteria which determine the price.
malachite is a carbonate mineral normally known as "copper carbonate"
kyanite, whose name derives from the greek word kyanos, meaning blue, is a typically blue silicate mineral, commonly found in aluminium-rich metamorphic pegmatites and/or sedimentary rock. Kyanite is a diagnostic mineral of the blueschist facies of metamorphic rocks.
kyanite is used primarily in refractory and ceramic products, including porcelain plumbing fixtures and dinnerware. It is also used in electrical insulators and abrasives. An interesting property of kyanite is that it undergoes an irreversible expansion when fired at high temperature. 
kyanite has also been used as a gemstone, though this use is limited by its anisotropism and perfect cleavage. Kyanite is one of the index minerals that are used to estimate the temperature, depth, and pressure at which a rock undergoes metamorphism. Finally, as with most minerals, kyanite is a collector's mineral
grow around a nucleus that is manually inserted into an oyster or mussel. Modern techniques place the nucleus within the soft body of the oyster, away from the shell, allowing it to grow freely. Older techniques place the nucleus between the mantle and the shell of the oyster, where the pearl develops as a “blister” attached to the inner shell.
Blister pearls are left attached to the shell backing and the shell is polished to a smooth surface. Blister pearls are often cut into lovely freeform shapes, showing both the inner shell and the pearl. They can also be cut so that just the round pearl is left. These are in essence “half-pearls” and are often used in earrings, rings, and pins where a flat back is desirable.
Some people call blister pearls “mabe (ma-bay) pearls”. This is only accurate if the blister pearl was grown in a Mabe oyster.
The Mabe oyster is a penquin wing oyster that produces blister pearls with better luster, iridescence, and color than other species. Mabe Blister Pearls have a rainbow spectrum of colors on their brilliant nacre, hence they are also called Rainbow Pearls.
Mabe pearl is also used to refer to the process of creating a half-pearl – even when the pearl was not grown in a Mabe oyster. These half-pearls are manufactured by a specific method – the cultured blister pearl is cut off the shell, the manually planted nucleus is extracted, the inside of the nacre coating is painted, the void left by the nucleus is filled with an epoxy, and the pearl is finished by covering the bottom with a polished piece of mother-of-pearl.

The fine branches of the coral sometimes look like small figures. Corals live at depths of between three and 300 metres in the waters around Japan, Taiwan and in the Malaysian Archipelago, in the Red Sea, in the Bay of Biscay and around the Canary Islands.
Corals are the product of tiny living beings which settled in enormous colonies in the
depths of warm seas long before our time.the corals grow like trees and branches. These can attain a height of sixteen inches (40 cm), though the actual branches seldom exceed one and a half inches (4 cm). At the forks, they are somewhat thicker. It is from these parts that the precious raw material for jewellery items, large coral beads or carvings is obtained.
Unprocessed, coral is matt. It is not until it has been polished that it takes on that beautiful shine. It is often porous, full of holes or cracked. Coral of that kind is sometimes filled with coloured wax to improve its appearance. High-quality coral is of an even colour and free of cracks and holes. Since genuine untreated coral is rare, it does fetch good prices.
Corals do not necessarily have to be red, even if red is thought of as their typical colour. Corals grow in Nature in a wide range of colours from red to white and from blue and brown to black. The most popular are the red hues such as pale pink or salmon, all the way out to a deep dark red. Black corals and gold corals are very much in fashion, whilst the blue ones are extremely rare.
