Quartz is the most common mineral found on the Earths surface. It is a significant component of many igneous, metamorphic and sedimentary rocks. This natural form of silicon dioxide is found in an impressive range of varieties and colours. There are many names for different varieties. Cryptocrystalline varieties of quartz are generally separated into chalcedony, which includes agate.
The main members of the quartz family are clear (rock crystal), smoky, citrine, rose, amethyst and prasiolite. There are also varieties of quartz with inclusions like rutile, tourmaline, copper and chlorite.
Jet is not actually a stone but the fossilised remains of the water logged monkey puzzle tree and occurs in black or dark brown and is a variety of coal known as lignite with the finest jet coming from England.

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.
Legend has it that Sulemani Agate comes from the mines of King Solomon with these stones being held until recently by the same Afghan family for over 400 years and once made up part of their tribal wealth. Regardless of the truth behind the legend the final look of these agate stone beads is generally man made with the contrast between the black and the white stripes, these beads are soaked in honey or sugar water. A technique that was invented by the mysterious Indus people.
Historically, Agate has been discovered with artifacts of the Neolithic people, and was used as healing amulets and ornamentation dating back to Babylon. Its medicinal uses continued through the ancient Greek and Egyptian civilizations, and spread throughout Africa and the Middle East into Russia. Agate sparked a world renowned stonecutting and polishing industry in Germany that flourished from the 15th to the 19th century, and exists today.
Agate is the name given to numerous varieties of banded Chalcedony, which is part of the Quartz family. Its name comes from the Achetes River in Sicily, where Agates were first found. Agates are usually banded in layers, stripes, or specks of colour, and some have fossilised inclusions, while others are solid.
