Types of stones

Many precious and semiprecious stones are used for jewellery. Among them are:

Amber

Amber, an ancient organic gemstone, is composed of tree resin that has hardened over time. The stone must be at least one million years old to be classified as amber, and some amber can be up to 120 million years old.

Amethyst

Amethyst has historically been the most prized gemstone in the quartz family. It is treasured for its purple hue, which can range in tone from light to dark.

Emerald

Emeralds are one of the three main precious gemstones (along with rubies and sapphires) and are known for their fine green to bluish green colour. They have been treasured throughout history, and some historians report that the Egyptians mined emerald as early as 3500 BC.

Turquoise is found in only a few places on earth, and the world’s largest turquoise producing region is the southwest United States. Turquoise is prized for its attractive colour, most often an intense medium blue or a greenish blue, and its ancient heritage. Turquoise is used in a great variety of jewellery styles. It is perhaps most closely associated with southwest and Native American jewellery, but it is also used in many sleek, modern styles. Some turquoise contains a matrix of dark brown markings, which provides an interesting contrast to the gemstone’s bright blue colour.

The word jewellery itself is derived from the word jewel, which was anglizied from the Old French "jouel", and beyond that, to the Latin word "jocale", meaning plaything. In some contries is spelled jewellery, while the spelling is jewelry inAmerican English. Both are used in Canadian English, though jewelry prevails by a two to one margin. In French and a few other European languages the equivalent term,joaillerie there, may also cover decorated metalwork in precious metal such as objects the art and church items, not just objects worn on the person.
